No exchange can guarantee security, and if they say that, then they are either stupid or deliberately trying to deceive you.
So, no crypto exchange in the world can guarantee their user data? And what I ever heard about their promise to keep KYC data safety is fake only?
If it is true, even Binance cannot guarantee our data? I am starting to be a bit afraid about my KYC data on Binance. I never imagine that even Binance can risk our data. This probably becomes a big problem if one day all centralized exchanges are investigated because of risking people's data around the world.
Yes, there's no guarantee that exchange can give full security of our data and avoid possible data breaches. A big exchange might also have data breaches even though big companies like Microsoft and Wattpad have experienced a disclosed data breach and even the big exchange like Binance was experienced before a data KYC breacH, AFAIK, that was way back in 2019.
However, if you really have paranoid feelings about your personal information that shouldn't expose and must your personal information private, find a decentralized exchange that is better for p2p transactions.
