I think it is wrong to call bitcoin a "private" currency.
On the contrary, imo bitcoin is much more of a public currency that any national currency is.
I agree with this, but to think that it was independently running without the aide of government people seems to interchange bitcoin with a private currency, and clearly it was okay, but in reality Bitcoin is separated with government and should always be in the way that it will not be controlled by government but mainly be by the local people, which may be better since there would be no center of power here in this community.
