Hi everybody,
Lately I am reading a lot of posts asking: is this airdrop a scam? Is that free ICO a scam?
So I am wondering how can something that doesn't cost you a penny be a scam. Sure, they get your email adress and maybe a ETH Adress, but how can you  really be scamed with only this informations? I am not talking about airdrops that require kyc registration, that for sure can be dangerous.
Cheers,
