Competition between local currencies Vs crypto currencies are in peak now. Crypto currencies have occupied currency market causing local currencies enforce (banks) banning of crypto currencies. We can see number of investors have turned towards to bitcoin and other crypto currencies with large scale. Will there be a chance / time bitcoin and other crypto currencies rule over currency market and local currencies get disappear slowly in a decade or two?
That depends on the people themselves. If they patronize crypto or bitcoins and they are practicing cashless trades or transactions then yes it can make paper money disappear; however, if these same people are imbecile crying out loud that they are neglecting paper money or local currencies, then their government will surely do something to stop them. Worst is, making bitcoin transactions a crime.
