I use a lot of website for airdrops, but the best one is https://freeairdrop.club/ there arent much projects but all of them are successful airdrops, I joined 3 of the 4 that you can see in the website and the 3 are really good projects with a lot of future, so I recommend you to join them. I think you only need a twitter account, and a discord account, that is all, good luck!
