It's amazing how all of this was based on personal credibility, and a single Tweet caused the death spiral to start.

Wells Fargo isn't going to go out of business if the CEO of Bank of America insults it on Twitter. But even if it did, there is FDIC insurance for deposits, and nobody whose balances were under the insurance limits will lose a penny.

FTX succeeded solely based on the reputation and personal credibility of its founder. One tweet from the CEO of a rival exchange and the whole thing came crashing down, taking a significant bite out of the value of many cryptocurrencies. So, even people who didn't have accounts at FTX are hurt by their assets losing value.
