Last year I participated in several airdrops, got a few coins of different, from some airdrops I got nothing, those coins that I received, not all can be sold on the any exchange, unfortunately, maybe in the future I'll take part in airdrops and maybe some of my old tokens from airdrops will rise a price and i could sell them, but airdrops takes a time and not the result is known, maybe I'm not quite so lucky with them, it's like roulette.
