So all on all... Nothing comes easy. Those Airdrops you think are free are actually NOT, you are trading your personal information and privacy which would be so expensive to acquire through legal ways for just a few cents in form of shit tokens.
Not at all, a lot of cheaters use fake information to join airdrops so it is free with them. I only join airdrop program if they do not ask KYC because I see the risk when you give someone your information to receive back few cents.
