as long as it's used correctly, I think KYC can be useful for cryptocurrency users. but the problem is if it is used incorrectly, because it involves a person's real identity. for countries that already support cryptocurrency, I think it will be safer if we do kyc, of course, it is already protected by the government. especially in Korea
many people agree to use KYC because it can reduce scammers, money laundering on an exchanger, and many more. but we also need to be careful in using our KYC. true, it is concerned with the personal data that we have, and when it falls on the wrong person or wrong place, I think it can be one of the new crimes. in fact, I heard that hackers also tried to steal KYC on the exchangers they hacked.
