How to know if the airdrop you joined is LEGit or not?
Not sure if there is a way since I fill up everything besides the donation part

Someone says that don't participate on airdrops that is asking for donation because one reason you are joining an airdrop is it is free so why donate?
Whitepaper and roadmap and team members. From my very short time in cryptos, it has done me well to do extra research before paying a dime.
Are you really paying for airdrops? As far as I know it is free so why pay? Or probably you are participating on those send 0 ETH with gas fee?
