The interesting thing is encouraging. But we're even earning if the value of bitcoin goes up.
Go with your interest but security is what matters most for someone like me. I don't think that exchanges will even give you a refund if they are hacked unless they are generous like Binance.
Even banks don't refund everything when they get bankrupt. In my country, account holders can only recover up to 500K no matter how much balance they have when their bank collapses. Exchanges probably have a worse policy when it comes to refund.
