> I want cryptocoins to return to the days about solving financial problems in new innovative ways.

What problems other than "how to sell drugs to suburban teenager online", "how to blackmail companies", and "how to run giant global ponzi schemes" has crypto actually solved in its 13 years of existence?

13 years after the invention of the WWW, there were almost a billion users, and it was increasingly transforming the world. If any of these crypto/blockchain ideas were actually useful, they would have been widely adopted by now for more than just criminal activity. The reality is that it's an interesting idea, but it's utterly useless for any worthwhile use cases.
