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?
I think not, local currency will not disappear and still be used for daily transactions so easy. And for cryptocurrency is better to use for investment.
