Youbit Shuts Down Cryptocurrency Exchange After Second Hack, Files For Bankruptcy (bbc.com)

phalse phace writes: After experiencing another hack, South Korean crypto-currency exchange Youbit has closed their doors and is filing for bankruptcy. BBC reports: "Youbit, which lets people buy and sell bitcoins and other virtual currencies, has filed for bankruptcy after losing 17% of its assets in the cyber-attack. It did not disclose how much the assets were worth at the time of the attack. In April, Youbit, formerly called Yapizon, lost 4,000 bitcoins now worth $73 million to cyberthieves. South Korea's Internet and Security Agency (Kisa) which investigates net crime, said it had started an enquiry into how the thieves gained access to the exchange's core systems. Kisa blamed the earlier attack on Youbit on cyber-spies working for North Korea. Separate, more recent, attacks on the Bithumb and Coinis exchanges, have also been blamed on the regime. No information has been released about who might have been behind the latest Youbit attack. In a statement, Youbit said that customers would get back about 75% of the value of the crypto-currency they have lodged with the exchange."

      That _is_ a problem with Bitcoin, because first, security requirements for normal banking are significantly lower as it is far harder to steal electronically from a normal bank. It requires deep insider knowledge, the right timing and getting the money out in some form that cannot be traced. And second, all these trading platforms are new, unregulated and hence cheaply and insecurely built. And if you do not believe that, check in a real bank what amount of security systemd, reviews, etc. they are merely doing because they are required to by law.

      Crypto-currencies are secure at a mathematical level, regarding payment which is the transfer of funds from one wallet to another.

      However payment involves compensation for the transfer of real-world assets, goods, and services, which is not covered (out-of-scope) of crypto-currencies, since regardless of how elegant the math is, there is simply no generic method to have any type of decentralized means of validating these real-world transfers. So we end up with a situation where "trusted" and "secure" 3rd party brokers are needed which act as crypto-currency intermediates between the buyer and seller, that can temporally hold the buyers purchase funds, in order to validate the transfer of real-world stuff from the seller to the buyer, before releasing the purchase funds to the seller.

      Everything falls apart at "trusted" and "secure". Any 3rd party brokers will need to hold a large pool of crypto-currencies for purchases, and will need to have some type of online presence and infrastructure, which makes it a prime target for online attackers wanting to rob it. (In the same way that thieves target banks, because that is where the money is.) However time and time again we see that these 3rd party brokers are untrustworthy or incompetent, typically without even providing the minimum of security measures.

      At the end of the day, this is where some government body (maybe from a different neutral country like Switzerland) will need to step up and implement some type of accreditation/certification of 3rd party brokers, that conform to the necessary regulation/protection and provide insurance protection, before crypto-currencies can really be trusted for transactions.

      When coins get stolen from a cryptocoin exchange it's the same thing as if hackers broken in to Goldman Sachs and stole money from your brokerage account. The difference is there are strict regulations and laws on brokers regard what they can and can't do and what they have to do. Security, privacy, managing funds, that kind of thing.

      Yes, it is telling you this kind of cryptocurrency doesn't really work.

      The most basic function of a "currency" is to settle payments, but transaction rate actually achievable (at least with the existing the Bitcoin) is so damn low that you simply cannot complete a transaction in reasonable amount of time, such as less than a minute.

      So, to actually do transactions effectively, people have to store their Bitcoins in exchanges, so any transaction within the exchange will simply result in a change of record in the exchange's accounting system, completely bypassing the use of blockchain transaction.

      Now, let that sink in for a moment.

      A supposed "currency" cannot support the most basic transaction of its users, to the extend people have to setup exchanges so they can transact that "currency" effectively. Is that not a big enough flashing sign saying Bitcoin simply doesn't work as a currency at all?

      And the people betting on Bitcoin continuing to rise? Just think about it, as the price of a Bitcoin rise to $50K, $100K, $1M, etc. Won't it eventually make more financial sense for every exchange to simply sell their coins and disappear? If they didn't get hacked first.

      Think about, if you were operating such an exchange, wouldn't YOU start secretly selling the Bitcoins you kept for your users, and just wait for the perfect moment to disappear with the money?

      Or if you are lucky, you might get hacked (so you blame all loses to the hacker) and declare bankruptcy (while hiding the money), or Bitcoin might just crash tomorrow so you can buy back all the coins with a tiny fraction of the money you took, then close off the exchange fair and square.

      Think through this, and then realize how much of a fool you need to be to bet on making money buying Bitcoins.

      People keep bitcoins in exchanges temporarily because they want to convert it to other currency.

      As if. If that's the real reason, there wouldn't be *millions* of dollars worth of Bitcoin stored in a single exchange to be stolen by hackers. The fact is people keep Bitcoins in exchanges because doing Bitcoin transactions otherwise is simply not practical.

      You are talking as if banks don't have similar problems. In fact, the main problem of the banking system (and arguably, the reason behind the bitcoin development) is exactly their breach of trust. Think about it, if you were operating a bank, with *no obligation to have an equal amount of gold in your vaults to match the credit you have outstanding*, wouldn't it make sense to lend out more money than you have? After all, it's just some numbers in a computer.

      Bank HAD the same problem, and that's exactly why banks are heavily regulated and there is this thing called FDIC. My money in the bank would be safe even if someone took all the money and ran away.

      Read up on the history of bank runs in American before banks were regulated. Bitcoin exchanges are now repeating the same mistakes people learned 100 years ago with banks.

      Some of us have vivid memories of our savings evaporating because some Icelandic bank collapsed. I think the appeal of bitcoin, for some, is the idea that we go back to having the currency under our own control. Like having a stack of bank notes under our mattress (yes, with all the associated risks and drawbacks).

      Your own fault with putting money in a bank not covered with any deposit insurance, and putting Bitcoins in any exchanges is even worse. Holding it in your wallet, your take on the risk of illiquidity instead (you can't sell them fast enough when needed). A real currency would not have the illiquidity problem.
