Don't waste time on airdrops, less than 1% of airdrops give you money. You will face a lot of risk when doing the airdrops, my Exchange account was attacked when I was not careful using the same mail to join some airdrop.
I know a lot of airdrop can get you some money, but it's not much. Only about $ 1 and it will take us a lot of time. It is best to join a bounty to help make our income higher
