The perfect theft in crypto is claiming that a project or an exchange is hacked when its all an inside job, the reason why I think about this is I have never heard about other top exchanges helping a exchange that just got hacked to track their funds and get some back at least but if it's a sole hacker from outside they will track him or them down, why is that?.
It is hard to determine which is a true hack or which was a planned / coordinated / man made hack by which separate exchange platform use as excuse to exit scam. Either true or fake, this lay more emphasis on why you should not keep or store your assets on centralized platforms. Get yourself a paper wallet; move your funds, trade, take profits, move them back to wallet after trade, rinse and repeat. The blockchain has zero emotions, so ensure you do the right things
I agreed with you, we shouldn’t hold any tokens in the centralized exchanges (even if which is top exchanges), because cex can be hacked at any time and exchange will not able to refund your money, though after a few big exchanges hacked they refunded their users money from their own fund as like Binance but mostly exchanges aren’t able to recover.
