It's a very reckless behavior from FTX team, mishandling customers fund, this has damaged their reputation. With this FTX failure, people will now be very much afraid of CEX. I personally hold significant of my fund on on my private wallets. DEX has made a lot simple.
It will become a trend that everyone will have to keep their assets through their hands now and wallets that they hold the private keys. Yeah, there might be a demand for the DEX for now and people would have turn their money from CEX to DEX and that's why they don't trust it anymore.
As a matter of fact, the event that has come to FTX is really their fault and they can't blame the people if most of their customers are now going away from them and not just them and to other the same exchanges that's also existing.
