The article analyzes the correspondence of the emergence of cryptocurrencies to two important theoretical ideas of the Austrian school of economics - the regression theorem of L. von Mises and the concept of denationalization of money by F. Hayek. The analysis shows the consistency of the new economic phenomenon with the regression theorem, since the posses-sion of bitcoin as an asset confirms the presence of some value before being used as a medi-um of exchange. Cryptocurrency competition is similar to the ideas of F. Hayek, but takes place in the conditions of maintaining the state monopoly on emission. At the same time, the commodity security of stablecoins corresponds to the commodity security of private currencies.

The article analyzes the correspondence of bitcoin, most common cryptocurrency, to the concept of "money". The analysis was carried out from the point of view of the possibility of explaining the origin of bitcoin from the standpoint of competing approaches (evolutionary, charter and debt theory) and the performance of bitcoin functions of money. It is concluded that despite the partial fulfillment of monetary functions, bitcoin is not a universal medium of exchange, i.e. money. Potentially it could reach such a state in the case if the state abandoned the monopoly on money and allowed free competition of all instruments of exchange, and bitcoin would win the competition from other possible applicants for the role of money.
