For someone who have spent his years buying on centralised exchanges only to have found privacy, passed countless KYC verification online, almost all their information is online, do they still have a choice at privacy?
Some people might not really know the value of their privacy early, they might have submitted their informations on exchanges before they realize they have made a great mistake, so they will want to look for a way to clean up things which is impossible, but I will say they still have choice at privacy. All what they will do is just to ignore the centralize exchanges which they submitted their details, and start making use of Decentralize exchanges, if the person doesn’t use the centralized exchange any longer, they not going to be able to monitor the person’s financial transactions.
What and what do you think they should start doing? Can such mess even get cleaned up?
Immediately you decide to submit your KYC on any exchange, then your information is already public, and there is no way you going to erase the information, so the only correction which you can make is to stop making use of those exchanges, and start using decentralized exchanges.
