I have joined a number of airdrops and only 1 airdrop has paid until now and still does not have an exchange and I have never produced anything from airdrops, so I have never joined airdrops and assume that most of the airdro scams
Maybe you should join Airdrop discussion channel in telegram. if you don't want to waste your time by joined airdrop, pick carefully and make a research about the project first, it's work for me since 2 years ago.. and i earn so much money from it.
