As I know, most CEXs require KYC before we can use them. Only a few do not require KYC but some features will be limited and withdrawal amounts will also be limited. I am not saying that DEX is superior to CEX, DEX does not have full functionality and has many shortcomings such as fees or liquidity that you mentioned. That is why to date investors and day traders still choose CEX over DEX despite collapses like Mt.Gox or FTX. But if someone is just a pure bitcoin holder and cares about privacy then DEX is the perfect choice for them.
I think the ones that do not require KYC is even worse trouble. I have talked about this before, all governments require you to ask for KYC if you run an exchange, if an exchange doesn't ask it then they are not responding to government demands and that's even worse. People like to label places like that as "rebel" and promote them but the reality is that government is not "always" bad, sometimes it works for you and should be something that benefits you one way or another.
I believe that we are going to end up with something that should be giving you the time you deserve but that doesn't mean that you are going to end up with a greater return if you know what you are doing. The best thing to do in this case would be making sure that you are not going to end up with a bad result.
