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 wonder why there're threads devoted to airdrop. I thought all clever people gave up airdrop in the middle of the previous year! It's a waste of time that won't allow you to break even. This doesn't worth it!
