We must agree that the cryptocurrency originated as a social movement and its main purpose was an alternative circulation in society to the official currencies established by the states, which were used as a means of payment. In addition, decentralized cryptocurrency, in fact, is not needed by states and their institutions. It is an invention of people and for people. But it seems to me that any add-on over the cryptocurrency will harm its decentralization. Such add-ons will pretend to establish some general rules of behavior for users, and this is not necessary for cryptocurrency.
