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
Yes, now the DEX has grown and improved a lot over itself 3 years ago. However, it can only pass CEX if the problem of fees and transaction speed improves, and it is possible that the coming ETH 2.0 will solve this problem.
