Since many states are new technologies and there is no regulation, they want to avoid cryptocurrencies. In fact, it would not be enough to stay away from their country of use with certain prohibitions to prevent the use of wants. Although this technology has reached a much better point in the states, although they will accept the use of these money are not suitable for the moment they are saying. Of course, although not in the near future, each state will create its own cryptocurrencies and these cryptocurrencies will be available to be regulated. Just like exchange rates, prices under state control will change digitally.
