And then on top of that the exchange itself is working against you. I repeat, do not throw away your hard-earned money this way!
Not your keys, not your coins. It's that simple. Exchanges are massive targets for hackers, and even the best ones have been breached, often with no clear explanation of how. We have seen alot of them in the past and more to happen in the future.. so Relying on an exchange means trusting them not only with security of your funds but also with your access, which can be arbitrarily frozen by KYC/AML requests.
why then should one take the risk of leaving their money in the hands of some people that can't even what their own back? It sounds ridiculous...
