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.
In my opinion the answer is totally no! world is far far away from being ready to integrate the cryptocurrency into its economy state, we just cannot imagine what a bunch of work needs to be done to do that and perform it.
