So, FTX was lending money just a few months ago, and now they are facing bankruptcy? sounds like a very bad joke.
All exchanges base their value/liquidity on the basis of investors' money. They borrow on that basis or even reinvest that money from their investors/customers and of course, it is a problem for liquidity when a large number of investors want to withdraw their money from there.
they should be aware of that and take care of other people's money a little more.
