Waxy is busy trading mstu and other stuff, seems to be doing well, with recent upturn in the bitcoin market
When was the last time a true Exchange hacked and people lost the ASSET? Sure brokers have gone belly up but there is SIPC or in UK FCA
Your argument doesn't hold weight. An exchange trading stocks is nothing like trading real currency. Why don't you tell us the last time a bank was robbed? That is what crypto is similar to.
It's pointless to even try to hack or steal stock assets and is not the same as trying to hack someone's funds or money. Nobody even wants to do that. Completely different things you are comparing.
