Typology of Digital Currencies
The goal of the present paper is to identify the main ways of use of cryptocurrencies and to clarify the place of cryptocurrencies in the system of digital currencies. Technological (use of distributed ledger) and organizational (absence of the center of emission) features of cryprocurrencies were identified. These features were used as a basis for a strategic classification matrix of digital currencies. Four main types of digital currencies were identified. It is demonstrated that cryptocurrencies can be divided into classic (decentralized) and centralized (collective) currencies. A description of specific features and prospects of development is given for each type of digital currencies. It is demonstrated that cryptocurrencies will mostly be used to increase the efficiency of payments, not as a substitute for traditional money. It is demonstrated that the refusal to use distributed ledger technology is not equal to refusal to use blockchain. Blockchain can be used to ensure high level of security for payment system with a sole emission center.
