The current legislation (which is constantly being amended) defines 4 types of tokens. We would like to emphasize that only one type is a digital currency, therefore it is not absolutely correct to call all tokens like that. They are: 1) Security tokens. They certify ownership and, in fact, are a digital (virtual) analog of traditional securities – shares, bonds, debentures, etc. 2) Digital currency. You can use it as a basis for exchange, any transactions, storage and accounting limits. 3) Secured tokens. They are secured by any real assets (securities, fiat money, gold, etc.). 4) Service tokens. These are designed to work with projects based on distributed registry technologies (blockchain).
