The issue of KYC always raises questions whose answers are mostly not very discerning to the ears. It is quite unfortunate, I know most crypto enthusiasts are not comfortable giving out their personal information for KYC but there is little we can do about the situation at the moment. Most of these projects claim they are under a legal jurisdiction where KYC is very important for many business projects. The new trend is increasingly becoming worrisome as many airdrops are even requiring KYC verification from participants.
Not even only to be under a legal jurisdiction but most people now are very greedy, opening many account for the same project to have more tokens dubiously. The only avenue to curb this is to do KYC, with this it is impractically impossible to claim for more than an account. This will ensure that only legit users are rewarded and token does not get into wrong hands that will be dumped immediately. Most genuine projects nowadays required KYC before distributing their token.
