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.
for this case it is not as fast or as easy as we imagine, but this hope can occur. see some developed countries have begun to legalize bitcoin in their respective countries. there is nothing wrong for us to expect more and help realize that all this can happen. because in the future all will turn to the digital world including virtual payments.
