But seeing the popularity of Bitcoin,it will be the world currency for a time.Only the bitcoin has been known in all the countries, which could not make any other coins.Everywhere they are Bitcoin,world Currency Will be.
I agree. Although, right now, it doesn't have the capacity to be one. I think that it has a very big potential to be a global currency because of the fact that there are so many users of it all around the world. At least, if it can reach a level where more and more people would trust it and be comfortable with using it as a means of investment and payment, then I would say that that can open a lot of doors for cryptocurrencies to be recognized as a probable candidate as a global currency. Maybe not by as a currency that would replace some traditional country-based currency, but at least, a type of currency that could be used around the world.
