This case will be long.
If you are talking about the security of your personal data, then I do not trust exchanges.
Well if that the case yes, we cannot trust any exchange although they say in their term of use that they will not abuse or sell our data bla bla bla hehehehe
and I hear about an app that said can remove our personal information but I dont think really know how the app works

Centralized exchangers have no future due to the many risks of working for them. You need to sell assets because prices are falling and the exchange is blocking your funds and asking you to submit tax returns.
If you have transferred your data on the Internet at least once, more than one service will not delete them from there.No matter how the exchanges resist, they will transfer all the trading data of clients over the past 6 years to the US tax and other services.
