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.
Man, there is no need to doing airdrop that asking for KYC to be eligible.
How much is the airdrop reward ? I don't think it will be worth to give your identity documents.
It will be better if you take a part of bounty campaign than airdrop campaign, but you need more efforts.
