I think that KYC is necessary for ICOs but it should be optional. We can't make passing KYC obligatorily. Many people want to stay anonym in crypto.

If the ICO project in which I invest will require to pass the KYC, then I will do it, since I chose this particular project. Providing your data to airdrop and bounty companies is complete nonsense. Okay, I'm ready to take the KYC with the bounty companies, but airdrop???
