Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network
Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value? So let's have a short history of various payment channel techs!
Generation 0: Satoshi's Broken nSequence Channels
Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product. Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger. Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore. In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction. So what you'd do would be something like this:
You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
Eventually you have to stop drinking. It comes down to one of two possibilities:
You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time. Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
I think I got sidetracked here.
Bears are bad news.
You can't reasonably invoke "Satoshi's Vision" and simultaneously reject the Lightning Network because it's not onchain. Satoshi's Vision included a half-assed implementation of payment channels with nSequence, where the onchain transaction represented multiple logical payments, exactly what modern offchain techniques do (except modern offchain techniques actually work). nSequence (the field, but not its modern meaning) has been in Bitcoin since BitCoin For Windows Alpha 0.1.0. And its original intent was payment channels. You can't get nearer to Satoshi's Vision than being a field that Satoshi personally added to transactions on the very first public release of the BitCoin software, like srsly.
Miners can totally bypass mempool rules. In fact, the reason why nSequence has been repurposed to indicate "optional" replace-by-fee is because miners are already incentivized by the nSequence system to always follow replace-by-fee anyway. I mean, what do you think those drinks you passed to Jihan Wu are, other than the fee you pay him to mine a specific version of your transaction?
Satoshi made mistakes. The original design for nSequence is one of them. Today, we no longer use nSequence in this way. So diverging from Satoshi's original design is part and parcel of Bitcoin development, because over time, we learn new lessons that Satoshi never knew about. Satoshi was an important landmark in this technology. He will not be the last, or most important, that we will remember in the future: he will only be the first.
Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is). Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender. Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender. First, you and the bartender perform this ritual:
You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds. So now you start ordering in this way:
For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
You sign the transaction and pass it to the bartender, who serves your first drink.
For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
At the end:
If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen. So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx... Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly. "I'm refusing service to you," the bartender says. "Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!" "Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed." "What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer. What you see shocks you. "What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!" "Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW." Lesson learned?
Payback's a bitch.
Transaction malleability is a bitchier bitch. It's why we needed to fix the bug in SegWit. Sure, MtGox claimed they were attacked this way because someone kept messing with their transaction signatures and thus they lost track of where their funds went, but really, the bigger impetus for fixing transaction malleability was to support payment channels.
Yes, including the signatures in the hash that ultimately defines the txid was a mistake. Satoshi made a lot of those. So we're just reiterating the lesson "Satoshi was not an infinite being of infinite wisdom" here. Satoshi just gets a pass because of how awesome Bitcoin is.
CLTV-protected Spilman Channels
Using CLTV for the backoff branch. This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015. Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed. This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction. With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to. Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time". With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.
Todd Micropayment Networks
The old hub-spoke model (that isn't how LN today actually works). One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel. Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable. So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user). In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today. Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy. Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.
Poon-Dryja Lightning Network
Bidirectional two-participant channels. The Poon-Dryja channel mechanism has two important properties:
No time limit.
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel. The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online. Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want. Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening. With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow. I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere. There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
You have to store all the revocation keys of a channel. This implies you are storing 1 revocation key for every channel update, so if you perform millions of updates over your entire lifetime, you'd be storing several megabytes of keys, for only a single channel. RustyReddit fixed this by requiring that the revocation keys be generated from a "Seed" revocation key, and every key is just the application of SHA256 on that key, repeatedly. For example, suppose I tell you that my first revocation key is SHA256(SHA256(seed)). You can store that in O(1) space. Then for the next revocation, I tell you SHA256(seed). From SHA256(key), you yourself can compute SHA256(SHA256(seed)) (i.e. the previous revocation key). So you can remember just the most recent revocation key, and from there you'd be able to compute every previous revocation key. When you start a channel, you perform SHA256 on your seed for several million times, then use the result as the first revocation key, removing one layer of SHA256 for every revocation key you need to generate. RustyReddit not only came up with this, but also suggested an efficient O(log n) storage structure, the shachain, so that you can quickly look up any revocation key in the past in case of a breach. People no longer really talk about this O(n) revocation storage problem anymore because it was solved very very well by this mechanism.
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network. Lessons learned?
We can decentralize if we try hard enough!
"Hubs bad" can be made "hubs good" if everybody is a hub.
Smart people can solve problems. It's kinda why they're smart.
After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time. The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory). Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough. Lessons learned?
Bitcoin offchain scaling is more powerful than you ever thought.
Investigating the $1B Bitcoins on the move from a SilkRoad related wallet
2 days ago, I reported that a SilkRoad related wallet containing about $1B worth of Bitcoins (111,114 $BTC and the same amount of $BCH and of other Bitcoin forks) was on the move after 4 years and 5 months of inactivity : https://www.reddit.com/Bitcoin/comments/9bfnff/near_1b_are_currently_on_the_move_from_a_silkroad/ Today, I will dig a little bit more into this wallet activity. Below you will find a graph representation of the transactions sent over time from the original 111,114-BTC wallet to the most recent wallets which have received some of the coins. Each branch represent a sequence of transactions sent through several wallets. Red nodes indicate the most recent transactions (< 1 month), blue nodes indicate quite recent ones (<1 year) and green nodes are the older ones ( > 1 year).
Picture 2: original coins are currently transferred on Binance wallet, in fact it is a major end-point/aggregate of transactions originated from the 111,114-BTC wallet (1NDyJtNTjmwk5xPNhjgAMu4HDHigtobu1s).
Picture 4: funds are currently actively mixed, you can see a chain of red nodes with no other purpose than transferring n time the coins and splitting/mixing it a bit (3Ah15skNb8R1teRWs6h2Q2vRywkLJWUhhb).
Hi Bitcoiners! I’m back with the fifteenth monthly Bitcoin news recap. For those unfamiliar, each day I pick out the most popularelevant/interesting stories in Bitcoin and save them. At the end of the month I release them in one batch, to give you a quick (but not necessarily the best) overview of what happened in bitcoin over the past month. And a lot has happened. It's easy to forget with so much focus on the price. Take a moment and scroll through the list below. You'll find an incredibly eventful month. You can see recaps of the previous months on Bitcoinsnippets.com A recap of Bitcoin in March 2018
$1B bitcoins on the move: MtGox vs SilkRoad origin and BTC price impact discussed
Preamble: it seems that my post was censored and removed on bitcoin... from now I will only publish my articles on btc and crosspost it. Freedom and freespeech matter to me. -- This is the 4th post of a series of articles dedicated to investigate $1B worth of bitcoins (111,114 BTC/BCH/... BXX) that were dormant since 2014 and started moving actively. The BTC coins were originally located at this address (1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a).
The facts that part of this funds (>13%) have been transferred in the past month to Bitfinex, Binance and Bitmex exchanges is discussed here.
The origin of the bitcoins was originally discussed here.
A deep-dive into the wallet activity was discussed here.
Today I am writing a short update to discuss the origin of the funds and some events that could be related both to this wallet and yesterday's price crash. Wallet's origin This question has been discussed a lot by the crypto community in the past year. Here is a summary of the most probable hypothesis for the 1933p wallet's origin:
Wizsec, a prominent Bitcoin security expert, seems to be pretty sure that the wallet belongs to a MtGox hodler and early investor, who is not a DPR or a SilkRoad user, per his Twitter post: https://twitter.com/wizsecurity/status/1037030003068653569 Finally, Wizsec and I agree that this wallet is not CSW`'s wallet despite it is mentioned in several court documents. Wizsec spent a lot of time debunking CSW's ownership claims earlier this year: https://twitter.com/wizsecurity/status/968337084837781504 What do you think about this wallet origin? ` BTC price crash Also, I wanted to report some events that could be related to this 1933p wallet activity:
$100M USDT were transferred (reported by u/whalecheetah) while the 1933f wallet owner was in the process of transferring approximately the same amount to several exchanges.
10,000 BTC buy order was filed last night on Bitmex with 8,030 BTC transferred from a Bitfinex user wallet while the 1933p wallet owner transferred approximately the same amount of BTC to Bitfinex since August, 24th.
Binance's deposit problems on 2019 arise from an known, age-old, property of cryptocurrencies, generally known as "malleability". On Feb 5, 2019, Binance was reported to credit, for a second time, some Nano user deposits that had already been credited months before. The presumed reason is that they were upgrading nodes and replaying the block chain, and didn't turn off the deposit engine for this replay. When the new blocks were replayed, they somehow generated new block identifiers on Binance's internal servers (that is, these blocks were not relayed to Binance from outside Binance). These new block identifiers (for old blocks) triggered the deposit processor to create new internal deposits for user accounts, causing these accounts to get unduly credited with extra funds. This general crypto issue has been known for ages and it is surprising that Binance was susceptible to it. For example, the standard bitcoin transaction ID can be changed in a variety of ways without invalidating the transaction. This is called transaction ID malleability. If an exchange considers transactions with new transaction IDs as new deposits, they are susceptible to double deposits. The reason exchanges don't get caught by transaction malleability is that they judge new deposits by the transaction details and not the transaction ID, which can be changed. They also don't credit a user until the transaction has been confirmed a few times. While going down, MtGox famously blamed their problems on bitcoin transaction malleability (even though no one could ever verify these claims). Even though exchanges have adopted workarounds, the general property is potentially problematic enough that bitcoin introduced a new type of transaction identifier with the segwit fork to address this general issue of malleability. The nano protocol doesn't include the concept of confirmations, so counting confirmations to validate deposits can't apply. However, this dissimilarity doesn't mean that the basic problem of transaction malleability isn't known. And it underscores that the general practice of checking transaction details is much better than relying on protocol identifiers (like block or transaction IDs). My understanding is that nano 17.1 fixed the underlying source of malleability that caught Binance, but in upgrading to the fix Binance's deposit processor was running the old protocol and processed a few second deposits.
A word of caution. All major exchanges are not even fiat gateways. The actual fiat in the system is likely grossly overestimated. Crypto is decoupled from USD. Implications.
First of all i should disclose i'm fully out of crypto since last Sunday, i'm just waiting for my EUR wire from Bitstamp as that has been my gateway since 2014. I would like to thank bitcoinmarkets for the good times, i've been around for a long time but not really participating that much, and even when I did i used throwaways. I decided to make this topic as a warning and to explain why I got out and why I think you should be very careful. So we have a situation in which: 1) 80% or more of trading is in USDT (tether) 2) Coinmarket cap is an accomplice to Bitfinex which implies USDT-USD parity. To which degree this is intentional, irresponsibility or just incompetence I would not know. Basically conimarketplace lumps all USDT trades and prices with actual USD trades and prices. If you go there https://coinmarketcap.com/ and try to select PAIR, you get THIS. No USDT, even though most exchanges are USDT. Even if most of liquidity is USDT. Again, this is a major factor in implying parity along with what Bitfinex/Tether try to do. As if this wasn't enough, they also willingly or stupidly inflate USDT price itself. I have to remind you Coinmarketcap is THE point of reference for all cryptosphere. It's oscilating Alexa rank is 100-400. Betfair (real life gambling company) for example uses coinmarket price average for their own system. etc. 3) If/when tethebitfinex crashes, not only does bitfinex crash, it will crash all crypto pairings using USDT on all exchanges using USDT. 4) There are very few fiat gateways. Until recently I assumed the major(top) exchanges have some kind of fiat pairing. I mean.. any respectable exchange would have some way of actually getting money in and out, right? I didn't even think to check. Well, they don't. Literally all the major exchanges are USDT (and/or another stablecoin or proprietary coin) and nothing else. No USD, no EUR, no fiat whatsoever. https://coinmarketcap.com/rankings/exchanges/ . Only the 11th one has actual USD pairing. Didn't check lower but most exchanges don't have fiat. I did a full check on Binance myself as it's the biggest exchange and I had an account there for lulz. There is no fiat. What does this mean? It means that an allegedly 200 BILLION market cap of all crypto has a fiat gateway of only a couple of exchanges. Most exchanges not using any fiat are not only immune to the risk, they offload risk on the much smaller exchanges that are fiat gateways. And on clients, of course. The cash side of the actual exchanges would need to have to siphon even a fraction of this are unimaginable. If any of these exchanges use crypto to evaluate their own fiat balance (it is illegal but crypto is hardly regulated or audited), they're fucked. 5) If the first four points looked bad, this one is by far the worst. The system is running on a presumed liquidity provided by Tether and on presumed USD capital. Even if tether was legit it's just 2b USD rolling 200b USD. And that 200b USD is just presumed quantity of USD that is in. We don't know how much USD is in the system, there could be and there probably is way less, as over the past 8 years or so crypto ran mostly on funny exchanges that could "provide" whatever USD value they wanted. More so, even if they went bust, people would usually get to withdraw crypto and store it on some other exchange. Even when an exchange was slowly withering, people just pulled out crypto and the exchange actual liquidity was hardly tested out. Or btc-e crashing or MtGox crashing. Their cash side crashed but "crypto" side did not crash. It was bailed out so to speak. So we have crypto running around that should've been worth 1/10 or 1/100 of it's price but it's instead running on par value with crypto on legit exchanges. This grossly inflates price. Even if tether (or other stablecoin) is legit, it can be drained in a couple of hours. What happens to the pairings of crypto/USDT? People just trade one bitcoin at the presumable price of 6k for 6k USDT that are 100% backed but have no value because there's no USD in the treasury? Who is stupid enough to deposit USD there to get stuck waiting for another fool to bail him out by getting himself stuck? edit: [Even if tether is 1%, it holds much more assumed/created value, which is the actual issue. Look at it this way. It only adds 1 cent to a real dollar market buy order for example. Each buy order made in a system that implies USDT:USD parity is now worth 1% more than a true USD purchase. Now repeat that buy order millions of times. It's not 1.01+1.01 times 1 million. It's more like 1.01$1.000.000 Each added value comes from USDT injection and USDT has to be liquid on the way down as well. It's added value to the market value is NOT it's market cap. That's a shitfest all "stablecoins" inject into the market, no matter how backed or audited they are.] As I was saying, all the exchanges that are not holding any fiat are immune to any crash or actual liability. If/when cryptos fail, they'll give you back any number of cryptos/stablecoins you had, even if they're worthless. It's just entries in a database. If/when USDT fails, all it's corresponding crypto prices will go to infinity. If you're holding any USDT, you can't get out of the exchange because 1 btc will cost infinity. If you're in any margin position, no matter where your stops are you'll get margin called instead, as stops are just suggestions in high/extreme volatility. You can't get out through fiat cause there's no fiat. Your only hope is you were actually holding crypto and they don't block withdrawals. Best case scenario you move your crypto to a fiat gateway exchange and hope to cash out there as fast as possible because it will have had become evident that cryptos were overvalued because of USDT (and even hypothetical USD in the system). Will most likely be too late as people that were already in fiat gateway exchanges already sold/cashed out. There will be enormous sell pressure. And no buyers. The whole stablecoin issuance is idiotic and I just hope it crashes now and we won't see another bubble built on presumed capital, cause that will hurt way more people. All of this is a mess. Crypto is completely decoupled from real fiat now. The potential money that are in the crypto sphere is exponentially greater than available money to trade out of. Or maybe we should be grateful for stablecoins for finally crashing a system that would've crashed anyway in the long run.
Diversifying your 2018 investment portfolio with high risk and low risk coins
After months of thorough research I put together the best portfolio in crypto in my opinion. The portfolio is divided into high risk, high return (100x) bets, medium risk medium return (10x) and low risk, low return (3x-10x). If you want to put $30k into crypto, here is what I recommend to get the best outcome.
1. $10k into high risk high return coins XSPEC, SUMO, ECC, ODN, BNTY, SNOV.
XSPEC and SUMO are 2 are privacy coins that are currently at a tiny market cap of $9M and $4M. 3 months ago, when Bitcoin was at its All-time-high, their market caps were at $113M and $32M respectively. In case, Bitcoin goes up to its ATH of $20,000 again, those 2 coins will go back to their ATH again, too. The thing is, altcoins behave the same as Bitcoin, only that they move at a much higher percentage than the big one, Bitcoin. For example, if Bitcoin goes up 30%, all small altcoins with a market cap under $10M, such as XSPEC, will go up by around 90%. Privacy coins such as Monero are one of the most sought after cryptocurrencies currently and experts expect a big rise of privacy coins 2018. XSPEC and SUMO are very similar in technology to Monero, maybe even superior though their market cap is 100 times less, since they are less than 1 year old. ODN, BNTY and SNOV are the small market cap coins with the biggest expected commercial use of the blockchain as a messenger (ODN), Bug-Bounty platform (BNTY), lead-generation (SNOV) and decentralized file storage (ECC). There already exists a file storage coin Siacoin at 20x the market cap of ECC without much reason for the big gap due to ECC's solid technology. There are a also a few more very small cap coins that I considered, such as DNA in the medical field, and ELIX, though I found their potential less convincing than that of the above mentioned cryptocurrencies.
2. $15k into medium risk medium return (10x) coins, COSS, POE, PRL, DBC, ENJ.
COSS is the platform coin of the COSS crypto exchange. It is an exchange like Binance, but it is seen as one of the best small and innovative exchanges that currently exist. They will also release their mainnet in a few weeks, which will give them another boost. DBC is one of the few cryptos that make use of artificial intelligence. They have a very strong team and are one of the few cryptos in the AI space. ENJ, this is probably the coin with the most real-world usage of all cryptos. There are already a few gaming coins out there, such as FUN and MobileGo, however, ENJ is one of the few that real numbers behind them. With more than 18 million users and 250,000 gaming-based communities, **Enjin* is among the world’s largest social gaming platforms. Recently, Enjin launched its cryptocurrency—Enjin coin—an Ethereum-based token to be used on a platform that allows for the development, distribution, organization, and trading of virtual goods. As of 2 weeks ago, they closed a partnerships with one of the biggest games, Minecraft and will be used as a currency within Minecraft. POE is a decentralized platform that allows publishers to license, identify, and monetize digital content such as blog posts, news articles, YouTube videos, audio/music, e-books and more. Here is a very good article about them. https://www.reddit.com/CryptoCurrency/comments/7oubqm/my_thoughts_on_poe_and_why_2018_could_be_big_fo PRL is a very interesting one. It gives website owners the ability to generate revenue from their visitors without having to feature pushy advertising by storing encrypted data, but by mining PRL. https://www.reddit.com/CryptoCurrency/comments/7t4o95/oyster_prl_is_going_to_change_the_internet_heres/
Ok let's get to the juggernauts. If you are rather conservative, Bitcoin and Ethereum will make you a good profit in the coming years, maybe even 10x if you're lucky. However, if Bitcoin goes 10x, all smaller altcoins go 100x, so it is worth diversifying a little. The thing is, Bitcoin's technology is very outdated. It cannot handle more than 20 transactions per second, it uses as much energy as a small country and with increased usage their fees will skyrocket again. This is the problem of 1st generation blockchains. Bitcoin cash has the same problem and while they can handle double as many transactions as Bitcoin due to their block size being twice as big, it's only a drop in the ocean, since they need to be able to handle 1000x as many transactions as now if they want to be used as a payment processor. A good comparison to get an idea for transaction volume is VISA, which handles a couple of thousand transactions per second and is able to handle 60,000 transactions /second at peak times. A crypto payment processor needs to be as good as that. However, 60,000 transactions (tx)/second isn’t even a good benchmark. It’s the same as comparing the number of faxes sent with the number of emails sent. If you want to surpass old technology, you should go for 100x the amount of usage. More on that in the paragraph about IOTA. I personally won't put anything in Bitcoin and Ether, because they are rather outdated cryptocurrencies now and they can only grow another 10x maximum within the next year or 2, while there are many other coins that can grow 100x or more within the same time frame. Now we have VeChain, a supply chain cryptotechnology. VeChain is already very mature and it is the most popular and loved altcoin next to Nano. It is a safe bet. Let’s get to IOTA. They have built a very exciting new technology. They are not using a blockchain, but a Tangle. It is a 3rd generation blockchain that has zero fees and instant transaction times. IOTA’s real world application is in IoT, Internet of Things. They are using their tangle to connect to and make transactions between millions of small devices, be it temperature regulator, heating, car, lights. Now you can see why a high transaction volume is so important, because these devices communicate multiple times every second with one another through these transactions. It is estimated that in 10 years time, 80 billion IoT devices will exist worldwide, which probably create 80 billion tx/second or more. IOTA is designed to do exactly that. Bitcoin can only do 10 tx/second. Currently, 8 billion IoT devices are connected to the internet. However, IOTA has not been stress tested at this volume. It is not yet clear that transactions will remain instant at this volume, nor is it clear if the Internet of Things will ever take off. Maybe there will only be 500 million Internet of Things devices ever, this is not sure. However, IOTA has the biggest potential for me. Let’s get to BNB. BNB has the same purpose as COSS. It is used on the Binance exchange to reduce your trading fees. That means, the value of BNB rises and falls with the success of Binance and Binance is now the second largest, most loved exchange. They currently process 10% of all crypto trades. Among the sea of scammy and unprofessional exchanges, Binance stands out as very professional, intelligent, fair, with excellent customer service. They will also soon release the first decentralized CryptoCurrency exchange in a month. I believe BNB will be among the top 10 cryptocurrencies within 1 year. Let’s get to the final one Nano. It is my personal overall favourite. It is what Bitcoin always wanted to be, only a lot better. While Bitcoin is still struggling with high energy use, extremely low transaction volume and high fees upon increased usage, Nano has all that figured out already. Similar to IOTA, they are also a 3rd generation blockchain technology. They have zero fees, instant transactions and one millionth the energy usage of Bitcoin. Furthermore, they have been proven to work flawlessly while maintaining a 1000 tx/second volume. They are a payment processor. Furthermore, it looks like Nano could replace BCH as a trading pair soon, since BCH trading pairs get little traffic, KuCoin has removed BCH trading pairs yesterday and there is already an exchange with that trades all of his currencies with Nano, called Nanex. All in all, NANO and IOTA are on par for me while IOTA has more potential but also more risk, since it still has some security issues that haven’t been ironed out yet and they are somewhat reliant on the success of the Internet of Things. However, if the internet of things, really permeates our lives as described above, IOTA will replace Bitcoin and become the one most used cryptocurrency. Here is an excellent article about IOTA vs. Nano https://hackernoon.com/iota-vs-raiblocks-413679bb4c3e
Having said all this, if you believe that Bitcoin has now reached its full potential already and will never ever be worth more than now, don't invest in crypto anymore. If you think that Bitcoin can potentially go to $20k again or to $40k or that cryptocurrencies will replace FIAT in 5 years, then you can look at 10x returns. Many people fall victim to the cognitive bias of thinking Bitcoin is too risky, while the maximum risk is losing everything they invested, which can be $2,000. Sure, it is annoying to lose $2,000, but I put the possibility of Bitcoin never going to more than $7,500 at maybe 1%, while I put the likelhood of it going up to $20,000 or $30,000 at 60%. So, the odds are in your favor. All in all, it's a large upside to a small downside. If you are very sceptical of Bitcoin, but you are looking to diversify your portfolio, $2,000 is a sane investment amount that yes, is annoying to lose, but won't change your life. If Bitcoin goes up again significantly, you will simply make a large amount of money. Small downside, large upside. If you already have a significant amount of money in crypto, it's better to shift away from Bitcoin. Yes, you will probably make a 2x to 3x on Bitcoin as well, but you can make 50x from the best altcoins in the same time. EDIT: I didn't include
NEM, because their market cap is too high for average uniqueness and potential
XRP, because they are centralised. It's too risky to say they will grow with BTC, since they are going against the philosophy of crypto.
LTC, because they are just as bad as BTC and BCH
EOS, because they have too many red flags
Cardano, because they don't have a product yet, too much hype
Stellar, because one of the founders was a MtGox founder and a large portion of Lumens are owned by the foundation/founders. Not worth the risk.
NEO, I almost included them, but they didn't make the cut. Good coin though.
Tron, because they can't write a proper white paper
Monero, because there are good alternatives at a fraction of the price.
DASH, because they are an ok coin, but nothing outstanding that convinced me
ETC, because they are the same as ETH
QTUM, ICON, OMG because their market cap is too high for average uniqueness and potential
Lisk, I almost included them, but they didn't make the cut. Good coin though.
Bitcoin gold, cheap copycat
Zcash, I almost included them, but they didn't make the cut. Good coin though.
Verge, shill factory, hype, bad vibe
DGD, because their market cap is too high for average uniqueness and potential
There are several good coins in the top 100 still, Waves, Ziliqa, WTC, PIVX, Bat, REQ, ENG, SKY, LINK, though all of the high risk coins I mentioned do the same or have a bigger or equal potential as them 20x smaller market cap. These top 100 coins aren't 20x better than the high risk coins, even if they were 5x times better, it would be better to invest in the high risk coins, because you would still make 4x more profit. That's why the medium risk coins are only starting at number 133, 140 and 202. This makes them are undervalued for being the best utility coins currently.
$1B bitcoins on the move: MtGox vs SilkRoad origin and BTC crash discussed
This is the 4th post of a series of articles dedicated to investigate $1B worth of bitcoins (111,114 BTC/BCH/... BXX) that were dormant since 2014 and started moving actively. The BTC coins were originally located at this address (1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a).
The facts that part of this funds (>13%) have been transferred in the past month to Bitfinex, Binance and Bitmex exchanges is discussed here.
The origin of the bitcoins was originally discussed here.
A deep-dive into the wallet activity was discussed here.
Today I am writing a short update to discuss the origin of the funds and some events that could be related both to this wallet and yesterday's price crash. Wallet's origin This question has been discussed a lot by the crypto community in the past year. Here is a summary of the most probable hypothesis for the wallet's origin:
Wizsec, a prominent Bitcoin security expert, seems to be pretty sure that the wallet belongs to a MtGox hodler and early investor, who is not a DPR or a SilkRoad user, per his Twitter post: https://twitter.com/wizsecurity/status/1037030003068653569 Finally, Wizsec and I agree that this wallet is not CSW`'s wallet despite it is mentioned in several court documents. Wizsec spent a lot of time debunking CSW's ownership claims earlier this year: https://twitter.com/wizsecurity/status/968337084837781504 What do you think about this wallet origin? ` BTC price crash Also, I wanted to report some events that could be related to this 1933f wallet activity:
$100M USDT were transferred (reported by u/whalecheetah) while the 1933f wallet owner was in the process of transferring approximately the same amount to several exchanges;
a 10,000 BTC buy order was filed last night on Bitmex with 8,030 BTC transferred from a Bitfinex user wallet while the 1933f wallet owner transferred approximately the same amount of BTC to Bitfinex since August, 24th. Was this deal prepared or was the buyer a bitcoin angel?
Want to relay my recent experience to help other canucks entering the cryptocurrency scene. I wanted to invest 100K in both main coins and some alt coins. Depositing that amount can’t be done using ETF/bank-transfeetc. – the only reasonably quick way is to wire funds. For wires, most exchanges have a percentage based deposit fee – something that makes absolutely no sense to me. Whether you wire 1K or 1MM, the amount of work for the exchange is identical, so it should be a flat fee. Deciding on an exchange is more complicated than that though: each one has their own rules for minimums/maximums, trading fees, supported coins, holding periods, and withdrawal fees. They also can vary greatly on the amount of time verification takes. One thing to note is that pretty much all exchanges don’t charge a fee for inbound crypto transfers. 2 months ago I signed up for 10 exchanges (Coinbase/GDAX, Binance, Coinsquare, Kraken, ezBTC, QuadrigaCX, Bitfinex, Gemeni, Bittrex, Poloniex) and was verified on 7 of them (I’m still in queue for Gemeni, Bittrex, and Poloniex). Verification times gave me what I thought was a decent indicator of the level and quality of support I would receive. Of these exchanges, some have what I believe to be relatively high trading fees (Gemeni .25%, Bittrex, .25%, ezBTC .30%, QuadrigaCX .50%) vs lower maketaker fees (GDAX 0/.3%, Binance .1/.1%, Gitfinex .1/.2%, Coinsquare .1/.2%, Kraken .16/.26%). Still others have high percentage based wire fees. And finally, there’s a big disparity between withdrawal fees: free on some exchanes, vs fixed rate based on the coin for others, vs Coinsquare’s insane fixed 0.0025 BTC regardless of what coin or the amount being withdrawn. So here are some observations on the exchanges. Please note that the below is not a reflection on any of the people who work at the exchanges. I’m sure they are working as hard as they can and are doing their best. It’s just my experience. It’s also not financial advice. Also, I’m only human so feel free to offer corrections or better advice. Coinsquare: amazingly fast verification time, and for very large deposits seems to likely be the best option as they will let you speak to a human being by phone and will waive the deposit fee (I didn’t know this until later though). I excluded them because of their high 0.5% percentage based deposit fee and their crazy high withdrawal fee. They also only have support for 6 coins. QuadrigaCX: I had a terrible initial experience with QuadrigaCX’s support, so I immediately excluded them. They have high trading fees and there are many complaints of support tickets being ignored or having extremely lengthy wait times. They have a crazy high 1% percentage based CAD wire fee, but offer free USD wires. Note that they only support wires for large amounts. GDAX/Coinbase: Loads of good reviews, but only has support for 4 coins. Seems like they also don’t have a fee for crypto withdrawals. You also can’t seem to wire CAD or USD funds directly to GDAX. I think you may have to wire USD funds to Coinbase and then transfer them over to GDAX (for free). Kraken: I created an account but the verification page just appeared blank for me. After a few days, their support team got back to me telling me that they had a bug and that I needed to create a new account using a different email address and try again. That worked. I decided to use them as they seemed like the best all-around alternative. I was impressed with their support response (they gave me an answer that worked and responded in days as opposed to weeks), they offer a no-fee inbound CAD wire, support 16 coins, and have low (though not free) crypto withdrawal fees. They have also been around a while and have a good reputation (They were picked to handle MtGox claims). Wiring funds to them was a hair-raising experience though. You basically need to send your funds to an unknown bank in Tokyo, Japan. Kraken also has two slightly different sets of wire instructions: one that is on their website, and the other that their support folks send out. Only one of them mentions that you should tell your bank not to use an intermediary that will convert your currency. If you do things properly, and are lucky, you end up only paying ~$40 in fees. But chances are, you don’t, and end up paying 4%! (see https://www.reddit.com/BitcoinCA/comments/7rd6k8/fees_when_sending_to_krakencom/). You also have no idea how much the fees will be until the money finally shows up in your account. That’s tremendously unsettling. Luckily my bank branch manager was familiar with crypto currency wires and helped me do things properly. But, the wire took over 2 weeks to show up (Jan 18th), and Kraken support is so overloaded that they didn’t’ respond, despite me escalating my support ticket several times. I eventually had to resort to a reddit post to get a response to my support ticket. I gave support my wire receipt and answered lots of additional questions to help them try to “locate” it. Perhaps the worst part of my entire experience was that while my wire was being located, the entire crypto market tanked by 50%...and no one would respond to my support ticket…I felt helpless. A Kraken support rep a few days ago said that they are handing >50K new user registrations per day and have >20K new support tickets per day. I feel they should turn off new user registrations until they are capable of servicing existing customers. This is what their competitors have done. I found it disheartening to learn that the only way to get a response to my support ticket was to complain via social media --- many others have found the same. While I was waiting for my wire to appear Kraken had a >48h outage. Prior to the outage, the site was almost unusable as you’d receive constant 50x errors (I found this out prior to wiring my funds). After the outage, I find that their site is still barely usable. Pages take 10-15 seconds to load and when they do load many times they display errors so you have to continually retry until things work. At the end of the day though, they did come through for me: my wire arrived safely. So with my funds in Kraken, I tried to use them to purchase crypto. But no matter what I tried, none of the CAD dollar trading pairs would appear. I logged out and back in a few times and 15 minutes later, it suddenly started appearing. With the flakiness in Kraken’s platform, I had no choice but to transfer everything to a more stable and faster exchange: Binance: These guys have their shit in order. Super simple site navigation once you get used to it, fast verification times, blazingly fast website and trading engine, more than 50 coins supported, etc. But, they don’t support fiat – you must use one of the other exchanges to buy crypto with fiat and then transfer in your crypto. Gotta say it again: everything is super fast. Not just the page loads, but also trading, email confirmations, and withdrawals. Trading takes a bit of getting used to as you aren’t really buying or selling crypto…you are instead “trading” one crypto coin for another. Depending on the coin you want to purchase, you might have to trade your coin for BNB (binance’s own coin) and then trade BNB for the coin you desire. Be Your Own Bank: One final word of advice. Binance is awesome, but don’t trust anyone as despite everyone’s best intentions: no matter how secure a platform is, it can and will be hacked. As soon as you have done your shopping, transfer your coins off to your own wallet. This is why withdrawal fees are important. You might be asking: in hindsight, if I had to do it all over again, what would I do differently? To wire CAD funds I would try to use Coinsquare if it’s a big amount (after re-reading other people’s recent reviews). For USD wires, I might try using Gemeni, but I still haven’t been verified by them and have been waiting for almost 2 months. Before using either I would re-test how long it takes for a support ticket to be responded to. If you do wire funds, don't wire an exact round amount like "10,000.00", instead I would wire "10,070.45" so that it's easier to locate if things go wrong. Once the account has been funded I wouldn’t hesitate to transfer everything to another exchange if I wasn’t happy with the platform, the number of coin offerings, or quality of service I was receiving: you can always come back when things improve. Things change so quickly so not sure how helpful this will be…just wished I had known some of the above before starting.
Okay, so when the issue about suspended XLM withdrawal from Binance arose, I don't think much about it. After all, just last month Polo has the exact same issue and they fix it in about a week. Since nearly all exchange use only 1 wallet for ALL their users, you can check their XLM balance and most of the time there'll be millions if not billions of XLM sitting there, easing yourself from worry of being mt goxed. So, just today out of curiosity I decided to check binance stellar wallet...Now, there's only about 100K XLM sitting on their wallet. You can check it by yourself, and compare it with other exchange wallet:
Now, I know that this doesn't mean that binance is mtgoxing us. A lot of possible scenario that I can think of is that they have another wallet to store XLM safely, or that they decided to create a new wallet and move the fund there. Or maybe they decided to apply 1 wallet per user policy, and begin redistributing user's XLM to each their own wallet (ala how XRP wallet works in Polo). It'll be nice though if someone from Binance can confirm what exactly happened, and whether our funds is still safe there or not, since the low amount of XLM on their public address kinda make me worried. There's no way an exhange with more that $100 million of XLM volume only has around 100K XLM on their wallet. EDIT: Apparently they have another wallet here and been transferring all of our deposit to that wallet. Why they decided to use separate wallet, I don't know though

Major Exchanges In finance, an exchange is a forum or platform for trading commodities, derivatives, securities or other financial instruments. The principle concern of an exchange is to allow trading between parties to take place in a fair and legally compliant manner, as well as to ensure that pricing information for any instrument traded on the exchange is reliable and coherently delivered to exchange participants. In the cryptocurrency space exchanges are online platforms that allow users to trade cryptocurrencies or digital currencies for fiat money or other cryptocurrencies. They can be centralized exchanges such a Binance, or decentralized exchanges such as IDEX. Most cryptocurrency exchanges allow users to trade different crypto assets with BTC or ETH after having already exchanged fiat currency for one of those cryptocurrencies. Coinbase and Kraken are the main avenue for fiat money to enter into the cryptocurrency ecosystem. Function and History Crypto exchanges can be market-makers that take bid/ask spreads as a commission on the transaction for facilitating the trade, or more often charge a small percentage fee for operating the forum in which the trade was made. Most crypto exchanges operate outside of Western countries, enabling them to avoid stringent financial regulations and the potential for costly and lengthy legal proceedings. These entities will often maintain bank accounts in multiple jurisdictions, allowing the exchange to accept fiat currency and process transactions from customers all over the globe. The concept of a digital asset exchange has been around since the late 2000s and the following initial attempts at running digital asset exchanges foreshadows the trouble involved in attempting to disrupt the operation of the fiat currency baking system. The trading of digital or electronic assets predate Bitcoin’s creation by several years, with the first electronic trading entities running afoul of the Australian Securities and Investments Commission (ASIC) in late 2004. Companies such as Goldex, SydneyGoldSales, and Ozzigold, shut down voluntarily after ASIC found that they were operating without an Australian Financial Services License. E-Gold, which exchanged fiat USD for grams of precious metals in digital form, was possibly the first digital currency exchange as we know it, allowing users to make instant transfers to the accounts of other E-Gold members. At its peak in 2006 E-Gold processed $2 billion worth of transactions and boasted a user base of over 5 million people. Popular Exchanges Here we will give a brief overview of the features and operational history of the more popular and higher volume exchanges because these are the platforms to which newer traders will be exposed. These exchanges are recommended to use because they are the industry standard and they inspire the most confidence. Bitfinex Owned and operated by iFinex Inc, the cryptocurrency trading platform Bitfinex was the largest Bitcoin exchange on the planet until late 2017. Headquartered in Hong Kong and based in the US Virgin Island, Bitfinex was one of the first exchanges to offer leveraged trading (“Margin trading allows a trader to open a position with leverage. For example — we opened a margin position with 2X leverage. Our base assets had increased by 10%. Our position yielded 20% because of the 2X leverage. Standard trades are traded with leverage of 1:1”) and also pioneered the use of the somewhat controversial, so-called “stable coin” Tether (USDT). Binance Binance is an international multi-language cryptocurrency exchange that rose from the mid-rank of cryptocurrency exchanges to become the market dominating behemoth we see today. At the height of the late 2017/early 2018 bull run, Binance was adding around 2 million new users per week! The exchange had to temporarily disallow new registrations because its servers simply could not keep up with that volume of business. After the temporary ban on new users was lifted the exchange added 240,000 new accounts within two hours. Have you ever thought whats the role of the cypto exchanges? The answer is simple! There are several different types of exchanges that cater to different needs within the ecosystem, but their functions can be described by one or more of the following: To allow users to convert fiat currency into cryptocurrency. To trade BTC or ETH for alt coins. To facilitate the setting of prices for all crypto assets through an auction market mechanism. Simply put, you can either mine cryptocurrencies or purchase them, and seeing as the mining process requires the purchase of expensive mining equipment, Cryptocurrency exchanges can be loosely grouped into one of the 3 following exchange types, each with a slightly different role or combination of roles. Have you ever thought about what are the types of Crypto exchanges?
Traditional Cryptocurrency Exchange: These are the type that most closely mimic traditional stock exchanges where buyers and sellers trade at the current market price of whichever asset they want, with the exchange acting as the intermediary and charging a small fee for facilitating the trade. Kraken and GDAX are examples of this kind of cryptocurrency exchange. Fully peer-to-peer exchanges that operate without a middleman include EtherDelta, and IDEX, which are also examples of decentralized exchanges.
Cryptocurrency Brokers: These are website or app based exchanges that act like a Travelex or other bureau-de-change. They allow customers to buy or sell crypto assets at a price set by the broker (usually market price plus a small premium). Coinbase is an example of this kind of exchange.
Direct Trading Platform: These platforms offer direct peer-to-peer trading between buyers and sellers, but don’t use an exchange platform in doing so. These types of exchanges do not use a set market rate; rather, sellers set their own rates. This is a highly risky form of trading, from which new users should shy away.
To understand how an exchange functions we need only look as far as a traditional stock exchange. Most all the features of a cryptocurrency exchange are analogous to features of trading on a traditional stock exchange. In the simplest terms, the exchanges fulfil their role as the main marketplace for crypto assets of all kinds by catering to buyers or sellers. These are some definitions for the basic functions and features to know: Market Orders: Orders that are executed instantly at the current market price. Limit Order: This is an order that will only be executed if and when the price has risen to or dropped to that price specified by the trader and is also within the specified period of time. Transaction fees: Exchanges will charge transactions fees, usually levied on both the buyer and the seller, but sometimes only the seller is charged a fee. Fees vary on different exchanges though the norm is usually below 0.75%. Transfer charges: The exchange is in effect acting as a sort of escrow agent, to ensure there is no foul play, so it might also charge a small fee when you want to withdraw cryptocurrency to your own wallet. Regulatory Environment and Evolution Cryptocurrency has come a long way since the closing down of the Silk Road darknet market. The idea of crypto currency being primarily for criminals, has largely been seen as totally inaccurate and outdated. In this section we focus on the developing regulations surrounding the cryptocurrency asset class by region, and we also look at what the future may hold. The United States of America A coherent uniform approach at Federal or State level has yet to be implemented in the United States. The Financial Crimes Enforcement Network published guidelines as early as 2013 suggesting that BTC and other cryptos may fall under the label of “money transmitters” and thus would be required to take part in the same Anti-money Laundering (AML) and Know your Client (KYC) procedures as other money service businesses. At the state level, Texas applies its existing finance laws. And New York has instituted an entirely new licensing system. The European Union The EU’s approach to cryptocurrency has generally been far more accommodating overall than the United States, partly due to the adaptable nature of pre-existing laws governing electronic money that predated the creation of Bitcoin. As with the USA, the EU’s main fear is money laundering and criminality. The European Central Bank (ECB) categorized BTC as a “convertible decentralized currency” and advised all central banks in the EU to refrain from trading any cryptocurrencies until the proper regulatory framework was put in place. A task force was then set up by the European Parliament in order to prevent and investigate any potential money laundering that was making use of the new technology. Likely future regulations for cryptocurrency traders within the European Union and North America will probably consist of the following proposals: The initiation of full KYC procedures so that users cannot remain fully anonymous, in order to prevent tax evasion and curtail money laundering. Caps on payments that can be made in cryptocurrency, similar to caps on traditional cash transactions. A set of rules governing tax obligations regarding cryptocurrencies Regulation by the ECB of any companies that offer exchanges between cryptocurrencies and fiat currencies It is less likely for other countries to follow the Chinese approach and completely ban certain aspects of cryptocurrency trading. It is widely considered more progressive and wiser to allow the technology to grow within a balanced accommodative regulatory framework that takes all interests and factors into consideration. It is probable that the most severe form of regulation will be the formation of new governmental bodies specifically to form laws and exercise regulatory control over the cryptocurrency space. But perhaps that is easier said than done. It may, in certain cases, be incredibly difficult to implement particular regulations due to the anonymous and decentralized nature of crypto. Behavior of Cryptocurrency Investors by Demographic Due to the fact that cryptocurrency has its roots firmly planted in the cryptography community, the vast majority of early adopters are representative of that group. In this section we cover the basic structure of the cryptocurrency market cycle and the makeup of the community at large, as well as the reasons behind different trading decisions. The Cryptocurrency Market Cycle Bitcoin leads the bull rally. FOMO (Fear of missing out) occurs, the price surge is a constant topic of mainstream news, business programs cover the story, and social media is abuzz with cryptocurrency chatter. Bitcoin reaches new All Timehigh (ATH) Market euphoria is fueled with even more hype and the cycle is in full force. There is a constant stream of news articles and commentary on the meteoric, seemingly unstoppable rise of Bitcoin. Bitcoin’s price “stabilizes”, In the 2017 bull run this was at or around $14,000. A number of solid, large market cap altcoins rise along with Bitcoin; ETH & LTC leading the altcoins at this time. FOMO comes into play, as the new ATH in market cap is reached by pumping of a huge number of alt coins. Top altcoins “somewhat” stabilize, after reaching new all-time highs. The frenzy continues with crypto success stories, notable figures and famous people in the news. A majority of lesser known cryptocurrencies follow along on the upward momentum. Newcomers are drawn deeper into crypto and sign up for exchanges other than the main entry points like Coinbase and Kraken. In 2017 this saw Binance inundated with new registrations. Some of the cheapest coins are subject to massive pumping, such as Tron TRX which saw a rise in market cap from $150 million at the start of December 2017 to a peak of $16 billion! At this stage, even dead coins or known scams will get pumped. The price of the majority of cryptocurrencies stabilize, and some begin to retract. When the hype is subsiding after a huge crypto bull run, it is a massive sell signal. Traditional investors will begin to give interviews about how people need to be careful putting money into such a highly volatile asset class. Massive violent correction begins and the market starts to collapse. BTC begins to fall consistently on a daily basis, wiping out the insane gains of many medium to small cap cryptos with it. Panic selling sweeps through the market. Depression sets in, both in the markets, and in the minds of individual investors who failed to take profits, or heed the signs of imminent collapse. The price stagnation can last for months, or even years. The Influence of Age upon Trading Did you know? Cryptocurrencies have been called “stocks for millennials” According to a survey conducted by the Global Blockchain Business Council, only 5% of the American public own any bitcoin, but of those that do, an overwhelming majority of 71% are men, 58% of them are between the ages of 18 and 35, and over half of them are minorities. The same survey gauged public attitude toward the high risk/high return nature of cryptocurrency, in comparison to more secure guaranteed small percentage gains offered by government bonds or stocks, and found that 30% would rather invest $1,000 in crypto. Over 42% of millennials were aware of cryptocurrencies as opposed to only 15% of those ages 65 and over. In George M. Korniotis and Alok Kumar’s study into the effects of aging on portfolio management and the quality of decisions made by older investors, they found “that older and experienced investors are more likely to follow “rules of thumb” that reflect greater investment knowledge. However, older investors are less effective in applying their investment knowledge and exhibit worse investment skill, especially if they are less educated and earn lower income.” Geographic Influence upon Trading One of the main drivers of the apparent seasonal ebb and flow of cryptocurrency prices is the tax situation in the various territories that have the highest concentrations of cryptocurrency holders. Every year we see an overall market pull back beginning in mid to late January, with a recovery beginning usually after April. This is because “Tax Season” is roughly the same across Europe and the United States, with the deadline for Income tax returns being April 15th in the United States, and the tax year officially ending the UK on the 6th of April. All capital gains must be declared before the window closes or an American trader will face the powerful and long arm of the IRS with the consequent legal proceedings and possible jail time. Capital gains taxes around the world vary from jurisdiction to jurisdiction but there are often incentives for cryptocurrency holders to refrain from trading for over a year to qualify their profits as long term gain when they finally sell. In the US and Australia, for example, capital gains are reduced if you bought cryptocurrency for investment purposes and held it for over a year. In Germany if crypto assets are held for over a year then the gains derived from their sale are not taxed. Advantages like this apply to individual tax returns, on a case by case basis, and it is up to the investor to keep up to date with the tax codes of the territory in which they reside. 2013 Bull run vs 2017 Bull run price Analysis In late 2016 cryptocurrency traders were faced with the task of distinguishing between the beginnings of a genuine bull run and what might colorfully be called a “dead cat bounce” (in traditional market terminology). Stagnation had gripped the market since the pull-back of early 2014. The meteoric rise of Bitcoin’s price in 2013 peaked with a price of $1,100 in November 2013, after a year of fantastic news on the adoption front with both Microsoft and PayPal offering BTC payment options. It is easy to look at a line going up on a chart and speak after the fact, but at the time, it is exceeding difficult to say whether the cat is actually climbing up the wall, or just bouncing off the ground. Here, we will discuss the factors that gave savvy investors clues as to why the 2017 bull run was going to outstrip the 2013 rally. Hopefully this will help give insight into how to differentiate between the signs of a small price increase and the start of a full scale bull run. Most importantly, Volume was far higher in 2017. As we can see in the graphic below, the 2017 volume far exceeds the volume of BTC trading during the 2013 price increase. The stranglehold MtGox held on trading made a huge bull run very difficult and unlikely. Fraud & Immoral Activity in the Private Market Ponzi Schemes Cryptocurrency Ponzi schemes will be covered in greater detail in Lesson 7, but we need to get a quick overview of the main features of Ponzi schemes and how to spot them at this point in our discussion. Here are some key indicators of a Ponzi scheme, both in cryptocurrencies and traditional investments: A guaranteed promise of high returns with little risk. Consistentflow of returns regardless of market conditions. Investments that have not been registered with the Securities and Exchange Commission (SEC). Investment strategies that are a secret, or described as too complex. Clients not allowed to view official paperwork for their investment. Clients have difficulties trying to get their money back. The initial members of the scheme, most likely unbeknownst to the later investors, are paid their “dividends” or “profits” with new investor cash. The most famous modern-day example of a Ponzi scheme in the traditional world, is Bernie Madoff’s $100 billion fraudulent enterprise, officially titled Bernard L. Madoff Investment Securities LLC. And in the crypto world, BitConnect is the most infamous case of an entirely fraudulent project which boasted a market cap of $2 billion at its peak. What are the Exchange Hacks? The history of cryptocurrency is littered with examples of hacked exchanges, some of them so severe that the operation had to be wound up forever. As we have already discussed, incredibly tech savvy and intelligent computer hackers led by Alexander Vinnik stole 850000 BTC from the MtGox exchange over a period from 2012–2014 resulting in the collapse of the exchange and a near-crippling hammer blow to the emerging asset class that is still being felt to this day. The BitGrail exchange suffered a similar style of attack in late 2017 and early 2018, in which Nano (XRB) was stolen that was at one point was worth almost $195 million. Even Bitfinex, one of the most famous and prestigious exchanges, has suffered a hack in 2016 where $72 million worth of BTC was stolen directly from customer accounts. Hardware Wallet Scam Case Study In late 2017, an unfortunate character on Reddit, going by the name of “moody rocket” relayed his story of an intricate scam in which his newly acquired hardware wallet was compromised, and his $34,000 life savings were stolen. He bought a second hand Nano ledger into which the scammers own recover seed had already been inserted. He began using the ledger without knowing that the default seed being used was not a randomly assigned seed. After a few weeks the scammer struck, and withdrew all the poor HODLer’s XRP, Dash and Litecoin into their own wallet (likely through a few intermediary wallets to lessen the very slim chances of being identified). Hardware Wallet Scam Case Study Social Media Fraud Many gullible and hapless twitter users have fallen victim to the recent phenomenon of scammers using a combination of convincing fake celebrity twitter profiles and numerous amounts of bots to swindle them of ETH or BTC. The scammers would set up a profile with a near identical handle to a famous figure in the tech sphere, such as Vitalik Buterin or Elon Musk. And then in the tweet, immediately following a genuine message, follow up with a variation of “Bonus give away for the next 100 lucky people, send me 0.1 ETH and I will send you 1 ETH back”, followed by the scammers ether wallet address. The next 20 or so responses will be so-called sockpuppet bots, thanking the fake account for their generosity. Thus, the pot is baited and the scammers can expect to receive potentially hundreds of donations of 0.1 Ether into their wallet. Many twitter users with a large follower base such as Vitalik Buterin have taken to adding “Not giving away ETH” to their username to save careless users from being scammed. Market Manipulation It also must be recognized that market manipulation is taking place in cryptocurrency. For those with the financial means i.e. whales, there are many ways in which to control the market in a totally immoral and underhanded way for your own profit. It is especially easy to manipulate cryptos that have a very low trading volume. The manipulator places large buy orders or sell walls to discourage price action in one way or the other. Insider trading is also a significant problem in cryptocurrency, as we saw with the example of blatant insider trading when Bitcoin Cash was listed on Coinbase. Examples of ICO Fraudulent Company Behavior In the past 2 years an astronomical amount of money has been lost in fraudulent Initial Coin Offerings. The utmost care and attention must be employed before you invest. We will cover this area in greater detail with a whole lesson devoted to the topic. However, at this point, it is useful to look at the main instances of ICO fraud. Among recent instances of fraudulent ICOs resulting in exit scams, 2 of the most infamous are the Benebit and PlexCoin ICOs which raised $4 million for the former and $15 million for the latter. Perhaps the most brazen and damaging ICO scam of all time was the Vietnamese Pincoin ICO operation, where $660million was raised from 32,000 investors before the scammer disappeared with the funds. In case of smaller ICO “exit scamming” there is usually zero chance of the scammers being found. Investors must just take the hit. We will cover these as well as others in Lesson 7 “Scam Projects”. Signposts of Fraudulent Actors The following factors are considered red flags when investigating a certain project or ICO, and all of them should be considered when deciding whether or not you want to invest. Whitepaper is a buzzword Salad: If the whitepaper is nothing more than a collection of buzzwords with little clarity of purpose and not much discussion of the tech involved, it is overwhelmingly likely you are reading a scam whitepaper. Signposts of Fraudulent Actors §2 No Code Repository: With the vast majority of cryptocurrency projects employing open source code, your due diligence investigation should start at GitHub or Sourceforge. If the project has no entries, or nothing but cloned code, you should avoid it at all costs. Anonymous Team: If the team members are hard to find, or if you see they are exaggerating or lying about their experience, you should steer clear. And do not forget, in addition to taking proper precautions when investing in ICOs, you must always make sure that you are visiting authentic web pages, especially for web wallets. If, for example, you are on a spoof MyEtherWallet web page you could divulge your private key without realizing it and have your entire portfolio of Ether and ERC-20 tokens cleaned out. Methods to Avoid falling Victim Avoiding scammers and the traps they set for you is all about asking yourself the right questions, starting with: Is there a need for a Blockchain solution for the particular problem that a particular ICO is attempting to solve? The existing solution may be less costly, less time consuming, and more effective than the proposals of a team attempting to fill up their soft cap in an ICO. The following quote from Mihai Ivascu, the CEO of Modex, should be kept in mind every time you are grading an ICO’s chances of success: “I’m pretty sure that 95% of ICOswill not last, and many will go bankrupt. ….. not everything needs to be decentralized and put on an open source ledger.” Methods to Avoid falling Victim §2 Do I Trust These People with My Money, or Not? If you continue to feel uneasy about investing in the project, more due diligence is needed. The developers must be qualified and competent enough to complete the objectives that they have set out in the whitepaper. Is this too good to be true? All victims of the well-known social media scams using fake profiles of Vitalik Buterin, or Bitconnect investors for that matter, should have asked themselves this simple question, and their investment would have been saved. In the case of Bitconnect, huge guaranteed gains proportional to the amount of people you can get to sign up was a blatant pyramid scheme, obviously too good to be true. The same goes for Fake Vitalik’s offer of 1 ether in exchange for 0.1 ETH. Selling Cryptocurrencies, Several reasons for selling with the appropriate actions to take: If you are selling to buy into an ICO, or maybe believe Ether is a safer currency to hold for a certain period of time, it is likely you will want to make use of the Ether pair and receive Ether in return. Obviously if the ICO is on the NEO or WANchain blockchain for example, you will use the appropriate pair. -Trading to buy into another promising project that is listing on the exchange on which you are selling (or you think the exchange will experience a large amount of volume and become a larger exchange), you may want to trade your cryptocurrency for that exchange token. -If you believe that BTC stands a good chance of experiencing a bull run then using the BTC trading pair is the suitable choice. -If you believe that the market is about to experience a correction but you do not want to take your gains out of the market yet, selling for Tether or “tethering up” is the best play. This allows you to keep your locked-in profits on the exchange, unaffected by the price movements in the cryptocurrency markets,so that you can buy back in at the most profitable moment. -If you wish to “cash out” i.e. sell your cryptocurrency for fiat currency and have those funds in your bank account, the best pair to use is ETH or BTC because you will likely have to transfer to an exchange like Kraken or Coinbase to convert them into fiat. If the exchange offers Litecoin or Bitcoin Cash pairs it could be a good idea to use these for their fast transaction time and low fees. Selling Cryptocurrencies Knowing when and how to sell, as well as strategies to inflate the value of your trade before sale, are important skills as a trader of any product or financial instrument. If you are satisfied that the sale itself of the particular amount of a token or coin you are trading away is the right one, then you must decide at what price you are going to sell. Exchanges exercise their own discretion as to which trading “pairs” they will offer, but the most common ones are BTC, ETH, BNB for Binance, BIX for Bibox etc., and sometimes Tether (USDT) or NEO. As a trader, you decide which particular cryptocurrency to exchange depending on your reason for making that specific trade at that time. Methods of Sale Market sell/Limit sell on exchange: A limit sell is an order placed on an exchange to sell as soon as (also specifically only if and when) the price you specified has been hit within the time limit you select. A market order executes the sale immediately at the best possible price offered by the market at that exact time. OTC (or Over the Counter) selling refers to sale of securities or cryptocurrencies in any method without using an exchange to intermediate the trade and set the price. The most common way of conducting sales in this manner is through LocalBitcoins.com. This method of cryptocurrency selling is far riskier than using an exchange, for obvious reasons. The influence and value of your Trade There are a number of strategies you can use to appreciate the value of your trade and thus increase the Bitcoin or Ether value of your portfolio. It is important to disassociate yourself from the dollar value of your portfolio early on in your cryptocurrency trading career simply because the crypto market is so volatile you will end up pulling your hair out in frustration following the real dollar money value of your holdings. Once your funds have been converted into BTC and ETH they are completely in the crypto sphere. (Some crypto investors find it more appropriate to monitor the value of their portfolio in satoshi or gwei.) Certainly not limited to, but especially good for beginners, the most reliable way to increase your trading profits, and thus the overall value and health of your portfolio, is to buy into promising projects, hold them for 6 months to a year, and then reevaluate. This is called Long term holding and is the tactic that served Bitcoin HODLers quite well, from 2013 to the present day. Obviously, if something comes to light about the project that indicates a lengthy set back is likely, it is often better to cut your losses and sell. You are better off starting over and researching other projects. Also, you should set initial Price Points at which you first take out your original investment, and then later, at which you take out all your profits and exit the project. That should be after you believe the potential for growth has been exhausted for that particular project. Another method of increasing the value of your trades is ICO flipping. This is the exact opposite of long term holding. This is a technique in which you aim for fast profits taking advantage of initial enthusiasm in the market that may double or triple the value of ICO projects when they first come to market. This method requires some experience using smaller exchanges like IDEX, on which project tokens can be bought and sold before listing on mainstream exchanges. “Tethering up” means to exchange tokens or coins for the USDT stable coin, the value of which is tethered to the US Dollar. If you learn, or know how to use, technical analysis, it is possible to predict when a market retreatment is likely by looking at the price movements of BTC. If you decide a market pull back is likely, you can tether up and maintain the dollar value of your portfolio in tether while other tokens and coins decrease in value. The you wait for an opportune moment to reenter the market. Market Behavior in Different Time Periods The main descriptors used for overall market sentiment are “Bull Market” and “Bear Market”. The former describes a market where people are buying on optimism. The latter describes a market where people are selling on pessimism. Fun (or maybe not) fact: The California grizzly bear was brought to extinction by the love of bear baiting as a sport in the mid 1800s. Bears were highly sought after for their intrinsic fighting qualities, and were forced into fighting bulls as Sunday morning entertainment for Californians. What has this got to do with trading and financial markets? The downward swipe of the bear’s paws gives a “Bear market” its name and the upward thrust of a Bull’s horns give the “Bull Market” its name. Most unfortunately for traders, the bear won over 80% of the bouts. During a Bull market, optimism can sometimes grow to be seemingly boundless, volume is rising, and prices are ascending. It can be a good idea to sell or rebalance your portfolio at such a time, especially if you have a particularly large position in one holding or another. This is especially applicable if you need to sell a large amount of a relatively low-volume holding, because you can then do so without dragging the price down by the large size of your own sell order.

Find the answer after reading this article. Public/Private Key The public key is the digital code you give to someone that wants to transfer ownership of a unit of cryptocurrency to you; and a private key is what you need to be able to unlock your own wallet to transfer a unit of a cryptocurrency to someone else. The encoding of information within a wallet is done by the private and public keys. That is the main component of the encryption that maintains the security of the wallet. Both keys function in simultaneous encryption systems called symmetric and asymmetric encryption. The former, alternatively known as private key encryption, makes use of the same key for encryption and decryption. The latter, asymmetric encryption, utilizes two keys, the public and private key, wherein a message-sender encrypts the message with the public key, and the recipient decodes it with their private key. The public key uses asymmetric algorithms that convert messages into an unreadable format. A person who possesses a public key can encrypt the message for a specific receiver. Accessing wallets Methods of wallet access vary depending on the type of wallet being used. Various types of currency wallets on an exchange will normally be accessed via the exchange’s entrance portal, normally involving a combination of a username/password and optionally, 2FA (Two factor authentication, which we explain in more detail later). Whereas hardware wallets need to be connected to an internet enabled device, and then have a pin code entered manually by the user in possession of the hardware wallet in order for access to be gained. Phone wallets are accessed through the device on which the wallet application has been downloaded. Ordinarily, a passcode and/or security pattern must be entered before entry is granted, in addition to 2FA for withdrawals. Satoshi Nakamoto built the Satoshi client which evolved into Bitcoin in 2009. This software allowed users to create wallets and send money to other addresses. However, it proved to be a nightmarish user experience, with many transactions being sent to incorrect addresses and private keys being lost. The MtGox (Magic the Gathering Online exchange, named after the original intended use of the exchange) incident, which will be covered in greater detail later, serves as a reminder of the dangers present in the cryptosphere regarding security, and the need to constantly upgrade your defenses against all potential hacks. The resulting loss of 850k BTC is a still unresolved problem, weighing heavily on the victims and the markets at large. This caused a huge push for a constantly evolving and improving focus on security. Exchanges that developed later, and are thus considered more legitimate and secure, such as Gemini and Coinbase, put a much greater emphasis on vigilance as a direct result of the MtGox hacking incident. We also saw the evolution of wallet security into the physical realm with the creation of hardware wallets, most notable among them the Ledger and Trezor wallets. Types of Wallets & Storage Methods The simplest way to sift through the dozens of cryptocurrency storage methods available today, is to divide them up into digital and non-digital, software and hardware wallets. There are also less commonly used methods of storage of private keys, like paper wallets and brain wallets. We will examine them all at least briefly, because in the course of your interaction with cryptocurrencies and Blockchain technology, it is essential to master all the different types of hardware and software wallets. Another distinction must be made between hot wallets and cold wallets. A hot wallet is one that is connected to the internet, and a cold wallet is one that is not. Fun fact: The level below cold storage, deep cold storage has just recently been implemented by the Regal RA DMCC, a subsidiary of an internationally renowned gold trading company licensed in the Middle East. After having been granted a crypto trading license, Regal RA launched their “deep cold” storage solution for traders and investors, which offers the ability to store crypto assets in vaults deep below the Almas Tower in Dubai. This storage method is so secure that at no point is the vault connected to a network or the internet; meaning the owners of the assets can be sure that the private keys are known only to the rightful owners. Lets take a quick look at specific features and functionality of varieties of crypto wallets. Software wallets: wallet applications installed on a laptop, desktop, phone or tablet. Web Wallets: A hot wallet by definition. Web Wallets are accessible through the web browser on your phone or computer. The most important feature to recognize about any kind of web wallet, is that the private keys are held and managed by a trusted third party. MyEtherWallet is the most commonly used non-exchange web wallet, but it can only be used to store Ethereum and ERC-20 tokens. Though the avenue of access to MEW is through the web, it is not strictly speaking a web wallet, though this label will suffice for the time being. The MEW site gives you the ability to create a new wallet so you can store your ETH yourself. All the data is created and stored on your CPU rather than their servers. This makes MEW a hybrid kind of web wallet and desktop wallet. Exchange Wallets: A form of Web Wallet contained within an exchange. An exchange will hold a wallet for each individual variety of cryptocurrency you hold on that exchange. Desktop Wallets: A software program downloaded onto your computer or tablet hard drive that usually holds only one kind of cryptocurrency. The Nano Wallet (Formerly Raiwallet) and Neon wallet for storage of NEO and NEP-5 tokens are notable examples of desktop wallets Phone Wallets: These are apps downloaded onto a mobile phone that function in the same manner as a desktop wallet, but actually can hold many different kinds of cryptocurrency. The Eidoo Wallet for storing Ethereum and its associated tokens and Blockchain Wallet which currently is configured to hold BTC, ETH and Bitcoin Cash, are some of the most widely used examples. Hardware wallets — LedgeTrezoAlternatives Hardware wallets are basically physical pathways and keys to the unique location of your crypto assets on the Blockchain. These are thought to be more secure than any variety of web wallet because the private key is stored within your own hard wallet, an actual physical device. This forcibly removes the risk your online wallet, or your exchange counter party, might be hacked in the same manner as MtGox. In hardware wallet transactions, the wallet’s API creates the transaction when a user requests a payment. An API is a set of functions that facilitates the creation of applications that interact and access features or data of an operating system. The hardware then signs the transaction, and produces a public key, which is given to the network. This means the signing keys never leave the hardware wallet. The user must both enter a personal identification number and physically press buttons on the hardware wallet in order to gain access to their Blockchain wallet address through this method, and do the same to initiate transfers. Paper Wallets Possibly the safest form of cryptocurrency storage in terms of avoiding hacking, Paper Wallets are an offline form of crypto storage that is free to set up, and probably the most secure way for users, from beginners to experts, to hold on to their crypto assets. To say it simply, paper wallets are an offline cold storage method of storing cryptocurrency. This includes actually printing out your public and private keys on a piece of paper, which you then store and save in a secure place. The keys are printed in the form of QR codes which you can scan in the future for all your transactions. The reason why it is so safe is that it gives complete control to you, the user. You do not need to worry about the security or condition of a piece of hardware, nor do you have to worry about hackers on the net, or any other piece of malware. You just need to take care of one piece of paper! Real World Historical Examples of Different Wallet Types Web Wallet: Blockchain.info Brief mechanism & Security Blockchain.info is both a cryptocurrency wallet, supporting Bitcoin, Ethereum and Bitcoin cash, and also a block explorer service. The wallet service provided by blockchain.info has both a Web Wallet, and mobile phone application wallet, both of which involve signing up with an email address, and both have downloadable private keys. Two Factor Authentication is enabled for transfers from the web and mobile wallets, as well as email confirmation (as with most withdrawals from exchanges). Phone Wallet: Eidoo The Eidoo wallet is a multi-currency mobile phone app wallet for storage of Ethereum and ERC-20 tokens. The security level is the standard phone wallet level of email registration, confirmation, password login, and 2 factor authentication used in all transfers out. You may find small volumes of different varieties of cryptocurrencies randomly turning up in your Eidoo wallet address. Certain projects have deals with individual wallets to allow for “airdrops” to take place of a particular token into the wallet, without the consent of the wallet holder. There is no need to be alarmed, and the security of the wallet is not in any way compromised by these airdrops. Neon Wallet The NEON wallet sets the standard for web wallets in terms of security and user-friendly functionality. This wallet is only designed for storing NEO, Gas, and NEP-5 tokens (Ontology, Deep Brain Chain, RPX etc.). As with all single-currency wallets, be forewarned, if you send the wrong cryptocurrency type to a wallet for which it is not designed, you will probably lose your tokens or coins. MyEtherWallet My Ether Wallet, often referred to as MEW, is the most widely used and highly regarded wallet for Ethereum and its related ERC-20 tokens. You can access your MEW account with a hardware wallet, or a different program. Or you can also get access by typing or copying in your private key. However, you should understand this method is the least safe way possible,and therefore is the most likely to result in a hack. Hardware: TrezoLedger Brief History Mechanism and Security A hardware wallet is a physical key to your on-chain wallet location, with the private keys contained within a secure sector of the device. Your private key never leaves your hardware wallet. This is one of the safest possible methods of access to your crypto assets. Many people feel like the hardware wallet strikes the right balance between security, peace of mind, and convenience. Paper Wallet Paper wallets can be generated at various websites, such as https://bitcoinpaperwallet.com/ and https://walletgenerator.net/. They enable wallet holders to store their private keys totally offline, in as secure a manner as is possible. Real World Example — Poor Practices MtGox Hack history effects and security considerations MtGox was the largest cryptocurrency exchange in the world before it was hacked in 2014. They were handling over 70% of BTC transactions before they were forced to liquidate their business. The biggest theft of cryptocurrency in history began when the private keys for the hot wallets were stolen in 2011 from a wallet.dat file, possibly by hacking, possibly by a rogue employee. Over the course of the next 3 years the hot wallets were emptied of approximately 650000 BTC. The hacker only needed wallet.dat file to access and make transfers from the hot wallet, as wallet encryption was only in operation from the time of the Bitcoin 0.4.0 release on Sept 23rd 2011. Even as the wallets were being emptied, the employees at Mt Gox were apparently oblivious to what was taking place. It seems that Mt Gox workers were interpreting these withdrawals as large transfers being made to more secure wallets. The former CEO of the exchange, Mark Karpeles, is currently on trial for embezzlement and faces up to 5 years in prison if found guilty. The Mt Gox hack precipitated the acceleration of security improvements on other exchanges, for wallets, and the architecture of bitcoin itself. As a rule of thumb, no small-to-medium scale crypto holders should use exchange wallets as a long-term storage solution. Investors and experienced traders may do this to take advantage of market fluctuations, but exchange wallets are perhaps the most prone to hacking, and storing assets on exchanges for an extended time is one of the riskiest ways to hold your assets. In a case strikingly similar to the MtGox of 2011–2014, the operators of the BitGrail exchange “discovered” that approximately 17 million XRB ($195 million worth in early 2018) were missing. The operators of the exchange were inexplicably still accepting deposits, long after they knew about the hack. Then they proceeded to block withdrawals from non-EU users. And then they even requested a hard fork of the code to restore the funds. This would have meant the entire XRB Blockchain would have had to accept all transactions from their first “invalid” transaction that were invalid, and rollback the ledger. The BitGrailexchange attempted to open operations in May 2018 but was immediately forced to close by order of the Italian courts. BitGrail did not institute mandatory KYC (Know your customer) procedures for their clients until after the theft had been reported, and allegedly months after the hack was visible. They also did not have 2 factor authentication mandatory for withdrawals. All big, and very costly mistakes. Case Study: Good Practice Binance, the Attempted Hack During the 2017 bull run, China-based exchange Binance quickly rose to the status of biggest altcoin exchange in the world, boasting daily volumes that surged to over $4 billion per day in late December. Unfortunately, this success attracted the attention of some crafty hackers. These hackers purchased domain names that were confusingly similar to “binance.com”. And then they created sufficiently convincing replica websites so they could phish traders for their login information. After obtaining this vital info, the scammers created API keys to place large buy orders for VIAcoin, an obscure, low volume digital currency. Those large buy orders spiked VIA’s price. Within minutes they traded the artificially high-priced VIA for BTC. Then they immediately made withdrawal requests from the hacked BTC wallets to wallets outside of the exchange. Almost a perfect fait accompli! But, Binance’s “automating risk management system” kicked in, as it should, and all withdrawals were temporarily suspended, resulting in a foiled hacking attempt. Software Wallets Web/Desktop/Phone/Exchange Advantages and Limitations As we said before, it is inadvisable to store crypto assets in exchange wallets, and, to a lesser extent, Web Wallets. The specific reason we say that is because you need to deliver your private keys into the hands of another party, and rely on that website or exchange to keep your private key, and thus your assets, safe. The advantages of the less-secure exchange or web wallets, are the speed at which you can transfer assets into another currency, or into another exchange for sale or for arbitrage purposes. Despite the convenience factor, all software wallets will at some point have been connected to the internet or a network. So, you can never be 100% sure that your system has not been infected with malware, or some kind of keylogging software, that will allow a third party to record your passwords or private keys. How well the type of storage method limits your contact with such hazards is a good way to rate the security of said variety of wallet. Of all the software wallets, desktop and mobile wallets are the most secure because you download and store your own private key, preferably on a different system. By taking the responsibility of private key storage you can be sure that only one person has possession of it, and that is you! Thereby greatly increasing the security of your crypto assets. By having their assets in a desktop wallet, traders can guard their private key and enjoy the associated heightened security levels, as well keep their assets just one swift transfer away from an exchange. Hardware Wallets Advantages and Limitations We briefly touched on the features and operation of the two most popular hardware wallets currently on the market, the Ledger and Trezor wallets. Now it will be helpful to take a closer look into the pros and cons of the hardware wallet storage method. With hardware wallets, the private keys are stored within a protected area of the microcontroller, and they are prevented from being exported out of the device in plain text. They are fortified with state-of-the-art cryptography that makes them immune to computer viruses and malware. And much of the time, the software is open source, which allows user validation of the entire performance of the device. The advantages of a hardware wallet over the perhaps more secure paper wallet method of crypto storage is the interactive user experience, and also the fact that the private key must at some stage be downloaded in order to use the paper wallet. The main disadvantage of a hardware wallet is the time-consuming extra steps needed to transfer funds out of this mode of storage to an exchange, which could conceivably result in some traders missing out on profits. But with security being the main concern of the vast majority of holders, investors and traders too, this slight drawback is largely inconsequential in most situations. Paper Wallets Advantages and Limitations Paper wallets are thought by some to be the safest way to store your crypto assets, or more specifically, the best method of guarding the pathways to your assets on the Blockchain. By printing out your private key information, the route to your assets on the Blockchain is stored 100% offline (apart from the act of printing the private key out, the entire process is totally offline). This means that you will not run the risk of being infected with malware or become the victim of keylogging scams. The main drawback of using paper wallets is that you are in effect putting all your eggs in one basket, and if the physical document is destroyed, you will lose access to your crypto assets forever. Key things to keep in mind about your Wallet Security: Recovery Phrases/Private Key Storage/2FA/Email Security Recovery phrases are used to recover the on-chain location for your wallet with your assets for hardware wallets like ledgers and Trezors that have been lost. When you purchase a new ledger for example, you just have to set it up again by entering the recovery phrase into the display and the lost wallets will appear with your assets intact. Private key storage is of paramount importance to maintain the safety of your on-chain assets! This should be done in paper wallet form, or stored offline on a different computer, or USB device, from the one you would typically use to connect to the 2 Factor Authentication (2FA) sometimes known as “two step authentication”. This feature offers an extra security layer when withdrawing funds from cryptocurrency wallets. A specialized app, most commonly Google Authenticator, is synced up to the exchange to provide a constantly changing code. This code must be entered within a short time window to initiate transfers, or to log into an exchange, if it has also been enabled for that purpose. You must always consider the level of fees, or the amount of Gas, that will be needed to carry out the transaction. In times of high network activity Gas prices can be quite high. In fact, in December 2017 network fees became so high that some Bitcoin transactions became absolutely unfeasible. But that was basically due to the anomalous network congestion caused by frantic trading of Bitcoin as it was skyrocketing in value. When copying wallet addresses, double check and triple check that they are correct. If you make a mistake and enter an incorrect address, it is most likely your funds will be irretrievably lost; you will never see those particular assets again. Also check that you haven’t input the address of another one of your wallets that is designed to hold a different variety of cryptocurrency. You would similarly run the very great risk of losing your funds forever. Or, at the very least, if you have sent the wrong crypto to a large exchange wallet, for example on Coinbase, maybe you could eventually get those funds back, but it would still entail a long and unenjoyable wait. How to Monitor Funds There are two ways to monitor you funds and your wallets. The first is by searching for individual wallet addresses on websites specifically designed to let you view all the transactions on a particular Blockchain. The other is to store a copy of your wallet contents on an application that tracks the prices of all cryptocurrencies. Blockchain.info is the block explorer for Bitcoin, and it allows you to track all wallet movements so you can view your holdings and all the historical transactions within the wallet. The Ethereum blockchain’s block explorer is called Ether scanner, and it functions in the same way. There is a rival to Ether scanner produced by the Jibrel Network, called JSearch which will be released soon. JSearch will aim to offer a more streamlined and faster search method for Ethereum blockchain transactions. There are many different kinds of block explorer for each individual crypto currency, including nanoexplorer.io for Nano (formerly Rai Blocks) and Neotracker for NEO. If you simply want to view the value of your portfolio, the Delta and Blockfolio apps allow you to easily do that. But they are not actually linked to your specific wallet address, they just show price movements and total value of the coins you want to monitor. That’s not all! You can learn how to transfer and monitor the funds in and out of your wallet by clicking on the link. To be continued!

The first centralized cryptocurrency exchanges had two main pre-historical roots of origin. Ideologically, they originated from the e-commerce exchange services of the early 2000s. Digital Currency Exchanges, or DCEs, were particularly popular in the U.S. and Australia. GoldAge Inc., E-Gold Inc., Liberty Reserve were frequently seen in the headlines mostly due to legal issues, as the U.S. SEC, as well as the Australian ASIC failed many times over to figure out whether the e-gold exchange was a form of banking, money laundering, non-licensed remittances or illegal entrepreneurship. These services exchanged fiat money on different digital currencies (1MDC, E-Gold, eCache etc.) and, in a way, fulfilled the demand of New World and EU citizens for anonymous transactions of digital and fiat money. But, in fact, the first significant cryptocurrency exchange arose from a surprising source… The website of the online game “Magic: The Gathering Online”. This game’s name refers to a magical world, where the currency system is represented in the form of cards. Jed McCaleb, the programmer from San Francisco and future contributor for Ripple and Stellar, developed the Mt.Gox project with the purpose of trading these cards like traditional stocks. In January 2007, he purchased the domain name mtgox.com, but in 2008, he abandoned the project as a premature venture. One year later, he used this domain to advertise his own online game. In the year of 2010, he read about the concept of Bitcoin and decided to launch the Mt.Gox exchange and exchange rate service allowing to trade Bitcoin freely. The project was released on July 18, 2010. Rapid commercial growth started when the product was sold to the French-Japanese developer Mark Karpeles in January 2011. It was the year 2011 when Mt.Gox demonstrated the main security challenges that traditional centralized exchanges will encounter all along their development path in the future. These included direct thefts from the platform’s wallets, attacks with multiple ‘ask’ orders, malefactor invasions resulting in price drops (one day, in the spring of 2011, 1 BTC was worth less than 0.01 USD) etc. By the way, the dramatic collapse of February 2014, with more than 750K BTC lost and the $65M civil suit in Tokyo court were still to come. During the years 2012–2013, every 3 of 4 Bitcoins in the world was sold via Mt.Gox, and it was a real success story. The years 2011–2012 gave birth to the bulk of top centralized cryptocurrency exchanges. BTCC was founded in June 2011 as the first exchange for the Chinese market. At the same time, American developer Jesse Powell had spent a month visiting Mt.Gox offices to offer assistance in the aftermath of the first hack. He was unsatisfied with the level of business organization, and that was how Kraken was founded in July 2011. The infamous BTC-e platform for exchanging rubles for BTC was also launched in July 2011. In late 2011, the largest American exchange BitInstant was founded and started selling Bitcoin via WalMart and Walgreen. 2012 became the year of origin for Bitfinex, Coinbase (first Ethereum marketplace) and LocalBitcoins.
Pros and Cons of Centralized Exchanges
We are now six or seven years away of those days. Today, hundreds of centralized exchanges are offering the services of exchanging BTC, ERC-20 and another cryptos. We can even hardly classify them. Usually, specialists speak about three mainstream types of centralized exchanges. Trading platforms. They connect buyers and sellers to each other, allowing them to publish trading orders and take some transactional fees (most commonly 0,3 per cent from the taker of the liquidity). For example, Cex.io, BitFinex, BitStamp belong to this group. Usually, these platforms are characterized by a complicated interface, which is not suitable for newbies. Cryptocurrency brokers. If a trading platform is a local market where you buy goods from their producers, the broker is a small player on the market. They sell coins at definite prices while setting high fees, but allow acquiring cryptos in a simpler manner. Moreover, most of them support a broad range of payment tools. Coinbase, Coinmama, Coinhouse are among the most popular brokers. Peer-to-peer-services. They simply allow their users to publish announcements about operations with cryptos. The buyer and the seller directly negotiate the prices. It is even possible to find one selling crypto for cash in your neighborhood. The most remarkable example here is LocalBitcoins. As one can see, now the range of services offered is truly broad. By the way, there is a list of common complaints regarding centralized exchanges both from traders and crypto theoreticians. Safety. Even a single point of centralization can lead to the massive theft of users’ funds and keys. More than a million BTCs have been stolen by the time of writing of this article. Regulation. If the center (or even one of the centers) of a CEX is physically located in some country, the position of this country’s government on ICOs and crypto related issues becomes crucial for the future of the project. Legal restrictions in this sector are now imposed in the U.S., China, South Korea, India etc. When your exchange is centralized, the officials can arrest your cryptos for no reason. Moreover, the administration of the exchange can be involved in fraud with your private information and money. Speed. We have conducted some particular research on the speed of popular CEXs (Binance, Huobi, Poloniex, see p. 11). The results are sad: you can wait dozens of minutes waiting for the pending of your transaction. KYC/AML. There is nothing to talk about in this regard, we suppose. If you must send someone your photo, a scanned copy of your ID or even proof of income wanting nothing in return but to withdraw your own funds, it is not OK.
Decentralization: The Solution
Decentralization, as the initial meaning and internal essence of blockchain, smart-contracts and cryptocurrencies, was first italicized by Satoshi Nakamoto and even Nick Szabo in 1990–2000-s. The rise of CEXs resulted in an obvious contradiction, because blockchain-based currencies are being operated via centralized mechanisms just like Visa or MasterCard, but much slowly. Is it normal? Where is the next stage of evolution or, does it even exist in the first place? The answer was the main point of arguments in the crypto community during the year of 2017. In February, Vitalik came out with the suggestion about the nature of blockchain’s decentralization: “Blockchains are politically decentralized (no one controls them) and architecturally decentralized (no infrastructural central point of failure), but they are logically centralized (there is one commonly agreed state and the system behaves like a single computer)”. The only possible expression in the commercial implementation of ‘architectural decentralization’ is the decentralized exchange of cryptocurrencies. And the most advanced technology in this case is that of the Atomic Swaps — the direct peer-to-peer instant cross-chain transaction. CEXs were the natural and inevitable stage of development for cryptocurrency exchanges. By the way, the DEXs are coming: we found them (namely IDEX, EtherDelta and Waves DEX) on the list of the top-100 exchanges on Coinmarketcap. So, the Swap.Online team is on the right track.
