In recent years, cryptocurrencies have become increasingly present on the public and economic scene. The fact is that many new digital money are being born every day, and that the lives of many of them are too short and they fail to establish themselves as a reliable means of payment. In this regard, in order to maintain, validate and preserve their value, many of them try to link their value with both payment systems and other resources. The aim of this study is to analyze the world practice in the world of cryptocurrencies as a new financial instrument. The world practice in the world of cryptocurrencies and digital technologies shows that the subject of discussions is the status of cryptocurrencies at national and supranational level, as there are many positions of state institutions and the private sector on their status as a means of payment and trade.
