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?
If you have fund over the 1000 USD on coinbase wallet means it will ask you to verify the documents and self photo of yours to make the transaction to any wallet mate.
Then you need to verify the documents for most of the airdrops. Still I am not sure what is the reason for sharing the kyc details mate.
I dont know whats the connections of the things you are saying on here about coinbase, where its just normal for them to ask KYC details when you do already hit up a particular threshold which isnt really surprising and its normal for them to ask because once you do register you would able to agree to their ToS. If you do have funds then its normal for you to comply but its your choice but since we do talk about airdrops on here i dont see why an individual would need up to pass information just to get a small amount of tokens which they dont even have a sure value.
