Guys, how often do you join airdrop?
Are you taking part in any of them?
What is more, you can get tokens for testing a project's beta. For example, KickCity. You can get reward for testing this platform

You are right, I agree with you ! Now It have to alot of scam projects. Those airdrop just need your info or something like that to scam you ! Do not fill in any information when you don't know about the project
