If you have the time, patience and energy for the requirements, why not? But know that it's not all airdrops that worth it, some will waste your time as they are particular about their marketing and earnings, and they will use you and dumb you. While some would have good intentions, when the project is listed, the asset will fall and the airdrop will be worthless. And in some cases too, you might be so lucky that you make a huge money from airdrops. This calls for dedication and participation in multiple airdrops programs. I believe that if you carefully select about 10 of them, you should be able to be happy with 2-4 of them in the worst-case scenario.
