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.
Most of the whole humanity still does not even know that cryptocurrencies exists or for others who heard about it does not really understand how it really works in the first place. Some big nations like the America and Russia uses it but it really does not make any big effect on the other parts of the globe because they don't understand it's importance and the benefits it can give to the whole world.
