In general, the regulation of the cryptocurrency market by states should have a very positive effect on its development. Regulation of cryptocurrency does not directly mean violation of its principle of decentralization. As a rule, it is only the establishment of the legal status of cryptocurrency, the determination of the order and conditions of its circulation within the state and, of course, the solution of the question of its taxation. Yes, it should be recognized that the level of our confidentiality and anonymity in the regulation of cryptocurrency will inevitably decrease. In any case, this requires the solution of tax issues. However, instead of a cryptocurrency can quickly grow and bypass ordinary people. Without legalization of cryptocurrency, it will not be distributed as a means of payment.
