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'd be lying if i said the world is ready for cryptocurrency, maybe technically they are. But, in fact there are some country that still can not accept bitcoin and banned bitcoin. I think the world will be ready at least 5 years from now.
