Some airdrops require personal info from their users like government approved ID proof, a selfie with it, contact number, email, address etc. Does this information really required? How to know if somebody is scamming you for asking this kind of information?
Dont join airdrops whom requiring KYC to be able to receive their coin. Dont ever risk your personal information for some shitty coin out there. I think that airdrop is a scam who just want to gather many information to sell in black market. So stay away to that kind of airdrops.
