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.
not yet because until now i can say that 20 percent in all over the world are the one who knows about cryptocurrency but i think we need more years maybe 5 yesrs is more good to all people in the world will know all about cryptocurrency and what it is.
