I think yes
because we know KYC's safe use because we know before you can make KYC lots of valid IDs. so do not worry about giving the wallet address because hackers can not open it.
wait what? did you say that it's safe to send KYC to some random ICO? An airdrop usually to gather attention like some sort of ads and it's for a new emerging ICO, do you want to gamble your identity for a chance to score 5$? , I'm not saying that airdrop was bad but the requirement is ridiculous
As many stated before above, it's not worth it for an airdrop. Maybe if you participate in some ICO and they need it for regulation.
