In my opinion, now one of the worst scenarios for the development of events may be the call of states for strict regulation of the cryptocurrency. There is already information that at the next summit of the G7 countries they can again discuss this issue and, among the proposed measures for universal adoption, the issue of prohibiting citizens from having cryptocurrency wallets will be discussed. This will actually mean the beginning of a war of states with cryptocurrency. There will hardly be winners in such a war, but everyone will lose.
