I don't agree with you on this, centralized exchanges are still as risky as they have always been. Data, personal info and funds have never been safe with them, and isn't still safe with them right now. Hacks still happen and centralized exchanges are still going bankrupt with many people losing all their money they kept with them and their private data is also published to the public. We may think this or that centralized exchange is reputable until something goes quickly wrong, and their users now have to worry not only about their lost funds, but their safety because their personal data could then be in the hands of anyone.
