That can happen, because decentralized exchanges have features that are easier, faster, and without complexity.
Today, centralized exchange has a rather complicated system to ensure the security of user accounts with the KYC system. Of course this can be a plus and minus point. While decentralized exchange does not have that system, but they use a peer-to-peer system and we don't need to worry about the data we enter because they don't store it in the database.
So, let's see in the future. What's better? to be honestly, I still like to use both because they have their advantages and disadvantages.
