I think most people have misunderstood that the world currency means the single currency in the world. However, I believe that Bitcoin has the potential to become one of the dominant currencies in the fund transfer industry but that does not mean that Bitcoin will be the only currency. At this stage, no 10% of the global population uses Bitcoin so it has the ability to grow at an exponential rate in the coming years. I don't expect bitcoin to change the country's currency immediately. When the world migrates from Manuel to digital we also need digital currencies that will eliminate third party interference. I think bitcoin will be used together with our traditional fiat. The choice will depend on the individual.
