The article deals with an important and relevant topic–the definition of the concept and essence of cryptocurrencies, the study of the problems of their legal regulation, the rationale for control over their turnover, as well as the analysis of ways to counter money laundering that involves cryptocurrency. The authors emphasize that measures taken exclusively at the state level are not enough to create an effective, integrated and comprehensive system for regulating the legal status of cryptocurrencies. Therefore, international cooperation and the strengthening of cooperation between various states in the field of cryptocurrency regulation is important.
