Decentralized exchanges need to take over centralized exchanges in the future, going fully decentralized is what makes more sense around crypto, centralized exchanges can be controlled by the law and government, I heard court is asking users data from centralized exchanges too, just imagine if all exchanges in crypto space are all DEXs, I know that DEX has its flaws too but it's safer than centralized exchanges
as long as transaction fees are still high it is difficult to get people to switch to DEX. just look at how much to pay just to transfer ERC20 tokens, the amount is sometimes not worth what you will get. this is a problem that must be resolved, and added to the many blockchain networks that exist today. it is difficult to create a DEX platform that supports all networks.
so CEX remains the best choice today, and DEX is only used as an alternative even in the future.
