I agree that KYC should be for investors who invest in cryptocurrency projects through ICO, because governments of various countries prohibit investing in cryptocurrency projects and thats why KYC needed for ICO, well, there are also various other reasons why need KYC for ICO, but each cryptocurrency company that conduct ICO has its own views on this, but about KYC for bounty companies, this is certainly overkill, because bounty manager must check each participant and I think this will be enough, but as for KYC for aidrops, I agree, because there are always many cheaters and scammers.
