I risk creating a duplicate question. But I'll try.

A huge number of crypto assets are discussed here. In the neighboring sections, new projects appear every day. But these are all false, far-fetched and almost always unsuccessful undertakings. New “projects” absorb the incoming money flow, which does not benefit the industry, but enriches individuals.
All this created for some cunning rogue?

Yes, some projects look interesting and potentially. I like the idea of ​​global currencies for various use and applications. W/o traditional money. W/o state control.
Is it not better to leave the opportunity to develop what is, than to continue to spray funds on scoundrels?

I do not know how this works and is managed. If all this is basically without control, then the future of the cryptocurrency world looks vague. However, this is interesting, because in addition to the expected collapse, there may be unexpected surprises.
