I used to think that airdrops were just gimmicks until I participated in Gate's CandyDrop. Their activity is designed quite reasonably; the rewards are not given out all at once, but rather in stages and tasks. The more you do, the more you get. A few frens around me also participated, and we reminded each other to complete tasks, which was quite fun. Moreover, their prize pool for each round is transparent; you can see roughly how much you can get, unlike some platforms where you end up with nothing. I think if this kind of activity can continue long-term, it would really help with user retention. Many platforms are doing airdrops now, but there are not many like CandyDrop that can continuously attract participation.
