When the fiat money getting move to digital currency I mean there is some innovation such as online shop who accept the payment with digital fiat currency then I think cryptocurrency is really deserve to be accepted as well. Even, that is the new innovation from some merchant who will aplicating the cryptocurrency can be use for such thing. I know Brazil is the most country that opens up the using of cryptocurrency recently. This is will make some countries who have a problem to ban cryptocurrency on their countries and will try to accept them although for the first step they will accept them as an asset. Sooner mass adoption will come to cryptocurrency IMO.
