I also do not believe that traditional currencies will leave our lives, but I think that the cryptocurrency will be able to work with Fiat money on a level. I think I still need some time passed people to take bitcoin as a forum of payment.
business people should be willing to buy and sell on a large scale using the future currency, if the bankers and customers get used to using bitcoin then they will enjoy some conveniences that cannot be obtained if we use fiat currency. socialization of payments using bitcoin must be intensified so that the digital era quickly spreads to all levels of society.
