For most people, nothing other than CEXs is an option - because they are looking for simplicity and liquidity, which is often not the case with DEXs. Try to explain to the average person the advantages that Bitcoin has over fiat, and most will tell you that they don't see any advantages in it.

As for the hacking of CEXs, I think that, except for the few largest ones, all the smaller ones do not invest enough in the security of their platforms, but they obviously have no problem offering hackers millions of dollars to return some of their coins. Obviously the rule "prevention is better than cure" does not apply to them.
