My answer for this question 30% yes and 70 % no! The reason is whenever i fill KYC for any airdrop, only 30% time it will passed and rest 70 % time i will not get any answer or fail. So according to me, KYC for airdrops are useless. But if we think about it, then it is the best way to track fraudster. I think only bounties should have to apply KYC for participants where KYC for airdrops are not good!
Giving our identity for a small portion of airdrop is completely wrong. Why? because you are risking your identity who knows that the airdrop campaign is just created to gather information of it's participants then later on sell it online. I don't like too bounty campaigns asking their participants to pass the kyc. As much as i know KYC is required only for those people who wants to invest and not for their promoters. Think before we pass some documents online so we can avoid some necessary conflict.
