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.
At the present time, I don't think the world is ready for cryptocurrencies. People have yet to understand how the market fluctuates and if people start investing without them knowing it works, they may lose their investments. I guess the world will be ready in the next 5-10 years when the market is sure to have bigger values.
