Although there are a few countries who uses bitcoins and other cryptocurrencies now, I cannot help but wonder if the world is truly ready for this digital currency? It will certainly be hard to replace all currencies in the world but it could happen in a decade or so, perhaps even less? Still the question is, is the world ready? I think if this happens it might be one of the biggest changes that will happen worldwide.
i think the road is still long towards that. because not all countries accept cryptocurrency , only a few of them accept it. this will take a long time until it happens. well maybe the time will come when cryptocurrency is accepted all over the world.
