Now all states will be forced to consider the issue of legalization of the crypto currency. At the same time, they must determine its status, that is, what they consider to be a crypto currency, determine the conditions for its circulation on the territory of the country, and also solve the issue of its taxation. This is an inevitable stage in the development of the crypto currency. Therefore, if in Brazil are going to consider these issues, then in general it is very good. Simply, the solution to the crypto currency, the conditions for its circulation and legalization, as well as taxation may be different, loyal to the crypto currency, or vice versa, rigid.
