In general, it is safe to say that this whole story with token drops has formed a bubble. 
In fact, the situation is such that drops appeared as a way to distribute tokens and build decentralization. Over time, they became just a marketing tool. The project attracts users by promising a drop, based on the indicators created by these users, attracts investments. Then, when the time comes, the project gives tokens to all participants of this scheme. 
It would seem that the scheme is perfect, but not everyone can make money from it, someone has to lose money or time.
