the airdrop for me its super profitable to gained money, even its all free but you need also to support them, what i mean is if you buy some token or coin for better,. i know they dont yet if they success the project i just suggest its get to support them, even its small money you spend in that project but soon your spend money to his project your profit make 3x income.
I think airdrop profits are completely about luck. Many of the new coins are born dead, unfortunately.
I think the best thing to do is that, not expecting great thing from the airdrops. Because the most of them are just waste of time.
