The FTX collapse make many people lost their assets in the cryptocurrency exchange in one way or the other, which most future trader's was liquidated on the position as the market bleed heavily.
Actually, it's not just with the FTX collapse but also with other exchanges that have fallen.
Base on that, keep your crypto exchange is not really safe because anything can happen at anytime, if FTX can collapse, which other crypto platform can do that one day, and for holding a coin is good to spread your asset for a better position.
It's not advisable to keep your funds on exchanges. With FTX and other collapse, this gives the idea that we shouldn't be too confident trusting them our funds. If you're a regular user of an exchange and of course, it's no longer with FTX even if they have comeback as said in the news. You only need to deposit with the amount that you're fairly okay to lose with. But if you're an active daily trader, you know that everything can happen with your fund so, it's either you lose more or earn more. But never ever entrust them if you're thinking of keeping it in the long term.
