I think it depends as for me as they are many scams as well just getting your information. In some instances, we can be blind sometimes, mkay? I really do not join airdrops if it requires too needy to get your personal information.
I believe some people are not cautious as long as they can join airdrops. How about you? What are your thoughts about KYC in ICOS?
There is one airdrop that I joined in that requires KYC. I did not completed the process because I don't want to give my full private information. Cryptocurrency is to keep your privacy as investor and customer, and ye they are getting your info. This may lead to identity theft or further damage if the ICO doesn't take good care and confidentiality on your information . Just be cautious on those ICOs that are not legit.
