As I know, this is not the first time the exchange or other platform hold customer money in their pocket. it's obvious de facto, it's our money but they can't give to us.
You know, exchanges are just like banks, most of them are centralised and so they call the shorts, just like banks. You might have an account number which is synonymous to an account number and a password just like you've got on exchanges too.
True, but the exchanges are not made to bank our funds. They are made to exchange cryptocurrencies and we must use it according to its function .. to trade and not to bank our fund and keep it on the exchange. We will see how devastating it is if we keep on using exchanges as bank when the exchange got bankrupt or hacked (FTX the recent example).
It's truly centralized and you don't have access so, you've got to tread carefully. Try not to leave large amounts on an exchange. You identify the advantage you wish to benefit from, make use of it and your out.
Yeah, since they(exchange) own the key where we keep our funds(if we keep our funds on exchanges), they have all the power and authority to use our funds and we can't do anything about that.
