You said you didn't see any difference from a bank getting robbed. In the case of a bank getting robbed. The FDIC will give the people the money that was stolen and the insurance will cover the bank. In the case of Crypto exchange getting robbed the company as well as the people lose all their money with no return.
The people who steal the money get the money in both cases.
People have to store a portion of their crypto on exchanges. Anyone making a sell order has to put the money on there until it sells. Anyone with a sell order on an exchange when it gets hacked loses that money. Most people learned from MT GOX to not store money on an exchange unless you are buying and selling. This way you only lose what you were selling.
Sigh, that explains why stupid people lose faith in cryptos I suppose -_-
