It is not a private property since we are able to hold, sell, buy, earn, and invest them.  If it is a private property then it was regulated by a company or some people and the supply or the bitcoin would be really low.  And its price is truly so high because it was being regulated by a company.  They got hold of the price of it.  Its price is stable.  Maybe if it was a private property only some people have the capacity to have a bitcoin.
