You are just selling your identity on 25$ it was not free because you give your identiy to them, what if they had account breaching? what will happen to your identity? it was going to sell with someone without your consent so better choose where are you going to have a kyc if it is worth it or not.
You are right it feel's like it isn't really free since we need to do the KYC in order to receive this so called airdrop.
And for me it is not worth it, I wouldn't risk my personal information just to receive these airdrops.
We don't know what could happen to our personal information what could they do with it.
So we should really be careful about proceeding to KYC.
