I'm sure that's not the case. All people have already forgotten about the FTX crash and continue to keep their funds on other CEX. If we look at their reports, there are more than 50 billion dollars stored on binance. Long before FTX there was MtGOX.
Exactly. The FTX collapse is history. People forgot all about it, and moved on with their lives. CEXs will still be around with us for quite some time, since they're the main "gateways" from both the crypto and Fiat worlds. Governments can keep track of illegal actvities involving crypto thanks to CEXs. With DEXs and privacy coins, it's almost impossible to do that. These solutions are widely unpopular due to their steep learning curve. Not everyone is willing to learn and take responsibility of securing crypto funds.
CEXs are easy to use, cheap, and fast. It's this reason why they're still afloat. I've read rumors of an "FTX comeback", so things might turn in the right direction soon. Who knows if the defunct exchange turns into a hybrid platform (centralized + decentralized) in the future?
