The somewhat ironic part is that one of the core concepts of Bitcoin is that you can't counterfeit it. You can mathematically prove how many coins you own, if somebody sends you 3 BTC then once it's been validated on the blockchain you know that the money is now yours, they can't have lied, it can't bounce like a cheque Except this Bitfinex thing shows that while an amount of bitcoin can't be manipulated or counterfe…
> They're literally making up money as they see fit. I'm playing devil's advocate here (I agree that the whole Tether situation is concerning), but also genuinely curious - is this any different than what banks have been doing for forever with fractional reserve? Even if Bitfinex is overcommitted and there's more USDT in circulation than they have in USD reserves, is there a problem unless a lot of people try to conv…
In a bank with fractional reserves, the assets and the liabilities all add up. If I deposit $100, and the bank lends $80 of that out to someone else, the bank has liability to me of $100 and assets of $20 cash + $80 loan (a loan is an asset on a bank balance sheet). I can't immediately withdraw all $100, but it all exists.
The bitfinex thing is more akin to the Federal Reserve, which actually can just make up money out of thin air. The big difference between bitfinex and the Fed is that the Fed is a federal agency, created through a legislative process and operated with clear public policy goals. Whereas bitfinex is just some random people somewhere claiming they have $billions in the bank.
