Bitcoin, of course, can not be called a private currency. Apparently, the one who decided to call it that way, had in mind that bitcoin is most used by private individuals, and not by the state or its structures. However, this name will be incorrect, because in this case it is understood that bitcoin was created by a private person and belongs to an individual. Most likely, it should be called a people's currency. This will indicate that bitcoin belongs to people, and not to the government and it was created by the people, since its creator Satoshi Nakamoto has not been established and has not yet stated his right to his invention.
