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.
It may take quite a long time for the world to accept electronic money widely. I do not say it is not possible but it will take quite some time. Developed countries will be the place where crypto needs to demonstrate its ability further to ensure it has a larger development focus. If it succeeds in these markets, developing countries will soon become familiar with it.
