Bitcoin is a currency whether you accept it or not and it was never supposed to become the "world currency" it is supposed to be a global currency which it is.
You are right. I believe this is where the problem still lies when people believe that it is only when the government accepts that Bitcoin is a currency that we will understand this. Not all local currencies around the world are globally accepted at the other end of the world and those that do not make them currency where they are accepted.
Likewise, Bitcoin as we must agree is been accepted around the world by those that have already understood this and will not necessarily need that Government acceptance, or are they still saying it is not a currency in El Salvador?
