Bitcoin users largely shrug off latest $69m Bitcoin exchange heist

Hong Kong Bitcoin exchange Bitfinex announced that it had been hacked and 119,756 Bitcoins stolen which at current prices represents nearly US $69 million. Bitcoin prices dropped 20% after word of the hack became public but the price has since recovered.

It is not clear how the hackers were able to get hold of the cryptographic keys that protected the stolen Bitcoins. Bitfinex had instituted a new way of protecting its accounts that involved multiple signatures, one of which was held by BitGo, the creators of the system that was supposed to keep the Bitcoin accounts safe from exactly this type of hack.

The hack is the second largest in a long line of hacks that have targeted Bitcoin. The biggest hack was that of Mt Gox in which 744,408 Bitcoin were stolen over a 2 year period. All of the hacks have essentially targeted Bitcoin's main weakness which is how to store the details of the Bitcoin accounts safely.

A Bitcoin account is actually a cryptographic which links back to transactions on Bitcoin's blockchain. If the private key is lost, so are the Bitcoins that were associated with it. Likewise, if someone steals the private key, they have access to all of the Bitcoin that are associated with it.

Keeping the private key associated with Bitcoin safe has proved a challenge. The safest place for a private key is in "cold storage" somewhere that is not attached to the Internet. This means potentially on a USB drive or in specialised encrypted devices called hardware wallets. The simplest way is to simply write the number down on a piece of paper.

With all of these solutions, keeping them safe from being lost or damaged is still an issue. Devices and USB drives can also fail raising the possibility of losing the information stored on them. There is also the issue that at some point, they have to be connected to a network to access the Bitcoin and at that point, they could be compromised.

For exchanges, the issue with storing Bitcoin in cold wallets is that it limits their customers' access to funds and so exchanges always keep a certain quantity of Bitcoin in "hot wallets". Bitfinex and BitGo had trumpeted the security of their multi-signature protection of customers' wallets but according to other exchanges that are also using multi-signature mechanisms, it might have been the way Bitfinex had implemented their specific version of the system that was at fault.

What is remarkable is that despite the magnitude of the hack, the Bitcoin price has started recovering and everyone not directly involved in the loss of Bitcoins have carried on as if nothing had happened. It is possibly a testament to the completely decentralised nature of Bitcoin that problems like this are considered to be isolated issues and not systemic problems. Loss of Bitcoins is treated in the same way as the potential loss in value of the currency that occur on a daily basis through its ongoing volatility.

It also indicates that the demand for Bitcoin is still robust because not only has it shrugged off hacks of this type but it seemingly has not reacted negatively to the "halving" of the reward given to Bitcoin miners that occurred in July. There was an expectation (including my own), that the halving would have made the economics of mining even more unfavourable. In the past few months however, Bitcoin's price has rallied partially mitigating this effect.

It is worth stressing that the vulnerability exploited by the hackers was not associated with Bitcoin's underlying blockchain technology as some seem to have suggested. At the time of preparing this article, Bitfinex was still offline with no indication of what the problems were that led to the hack. Whether customers flee the site when they are allowed to access funds or not is yet to be seen. To everyone else though, this is just another day in the never dull world of cryptocurrencies.

That's because bitcoin is a pyramid scam, and it operates by the belief of people that the value has to go up eventually or else their investment is lost - a psychological bias. It's about selling something fundamentally worthless - a string of bits - to a bigger fool, who thinks they'll find an even bigger fool in turn, which leads to boom-bust cycles and naturally the recovery from a bust is just another boom.

Another point that leads to boom and bust bitcoin cycles is the fact that it's designed to undergo constant deflation as the ultimate number of coins is limited, wallets and coins are continuously lost, and people hoard the coins to make their value rise before selling.

Losing 20% of value overnight is just business as usual.

you hit the nail on the head. die hard bitcoiners will fight tooth and nail to prove otherwise though. i think its early adopters who have 50000 bitcoins that do the pumping and dumping. its just like a cycle, they keep using the same bitcoins over and over to pull the fiat out of the market. like right now, price went from $780 down to $465. THis was the group pulling all the fiat out of the system and at the low they buy back in again and keep the difference bewteen the various prices the sold and bought back in at. So now their cost average is $500 say, so when the price gets to $800, they sell the same bitcoins down to $600 buy back again and just keep recycling the same bitcoins. wall street money will never get in to the coins, they may use the blockchain , but not the coins. wall street is into sure ways to make money

The early adopters have something on the order of 6 million BTC because the first ones cost less than a penny a pop to mine or buy. The people who started it are basically laughing all the way to the bank, because they have so many coins they can crash the market whenever they want.

The Bitcoin Blockchain, will eventually be found to be the only usable, open, reliable and simple trust engine on the planet. No other Blockchains can be trusted to such level. What would something like that be worth?

It has all the marks.

1. you don't sell anything
2. it works by introducing ever-more new people into the scheme to bring money
3. when the people stop coming, the "economy" collapses

Bitcoin is literally like inventing a company that does nothing, and calling for people to invest on it on the basis that the more people invest the higher the price, and therefore they can sell it for profit later.

Bitcoin has fundamentally no value. It isn't based on a debt obligation like fiat money, and it isn't based on a material value like gold standard. It's literally nothing. Nothing makes the original creator to take bitcoin back as payment, which means its not even money.

Point being, if I write on a slip of paper "I owe you for 10 potatoes" and recieve 10 potatoes from you, we've created a fiat currency. You can then pass that slip of paper around as money and it retains value because someone else can bring it back to me and I have to respect it as payment because I now have a debt obligation.

If I give you a hunk of metal in exchange for potatoes, that's a material standard. I don't actually have to give you the metal right there, I can write a paper that says you own it, and that's money.

What Bitcoin does is, people do a bunch of arbitrary make-work on mining coins, simply wasting electricity. Like carrying water from a well to a lake. This creates neither material value nor a debt obligation, and the people who create the coins never need to accept them back in exchange. That means I get potatoes, you get BTC, and when you try to offer me the BTC back later I can say "don't need em".

And that's the scam.
