I want to know how to find airdrop or ICO project...how to check scam or real and how much profit airdrop can make...and if u have experience about airdrop or ico things can u share this exp in here:

You could actually find different threads about promising ICOs and airdrops here in the forum. It's better to look for good projects here in Bitcointalk so you'll have an idea about their legitimacy. We must know as early as possible if we're joining a trusted and legit project because, to be honest, scam projects are everywhere these days.
