From my own experience I can tell from all the airdrops that I know the top projects were only: Vite, Ontlogy, Dfinity. All others were shitcoins

Personally, I used to actively participate in various promising airdrops. After all, they regularly provided rewards. Unfortunately, over the past year the situation has changed dramatically for the worse. Therefore, I participate less and less in airdrops. I really hope that next year the situation will improve.
