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 believe some countries are ready to digital currency but others have still hesitant. For now, there are resistance because it is on its early phase of mass adoption. Adjustments are needed and system improvements must be implemented. This is to address some concerns especially the fraud cases.
