As far as I know, the countries of the European Union are quite positive about cryptocurrency. First of all, this applies to Germany, France, the Baltic countries and others. However, they are forced to introduce certain rules for its circulation, because due to the features of the cryptocurrency you have indicated, they need to fight primarily with the possible financing of terrorism. Indeed, in recent years, European countries have often been attacked by terrorists. Here we can not do anything and we only have to agree with such an attitude of states so that cryptocurrency develops and has an extensive infrastructure under the protection of the state.
