I don't believe in today's airdrops. Out of the ten airdrops where I took part as an experiment, only 2 have a very low value. The rest are the garbage that can't be sold. It's better not to waste your time on this kind of a dumb work.
Out of curiosity, the ten you participated, did you do some background check if they put a lot of effort into this, for instance, did the have a quality website with all relevant information such as wallpaper, roadmap, team? Not a guarantee but good indicators if they are trash.
