I prefer and agree if bitcoin does not become my currency prefer it as an investment commodity like gold / silver but in digital form, and I think if bitcoin remains an investment commodity it will be very good for economic development in all countries because it will not exist FIAT currency is replaced by bitcoin
You do not understand anything, gold and silver are a form of money and for thousands of years were the dominant form of money through the world, most people have no historic memory but this experiment in which all the currencies of the world are not backed by anything and are just a fiat currency has only existed since the seventies, that is right, this experiment has been live for a very short amount of time and it is already showing signs that it will fail.
