And that medium of exchange will be bitcoin, I really think that cryptocurrencies and fiat are going to coexist in the future, some people are very stubborn and are going to keep using the currency printed by the government even if that means that they lose everything but people like us who knows very well what is happening will only use bitcoin as a medium of exchange, in fact even right now I am avoiding using fiat as much as I can and I'm sure that in less than a decade I will be able to avoid fiat completely.
