I get the whole FTX issue, but if you really are into Bitcoin & crypto, then why haven't you kept your exchange wallets in check? I personally almost never used exchanges. P2P is what bitcoin is really about.
If you trade bitcoin/crypto especially with leverage, then you pretty much have no choice but to leave a chunk of your bankroll on FTX or whatever exchange. The only problem is if people leave funds on exchange unnecessarily(with funds not being actively traded).
