And before that, the Spanish Real.
Those are the latest 3 world currencies. We're about to enter the fourth one, Bitcoin.
It will take some time, but it will happen.
bitcoin wont replace the institutional reserves of the world government collective..

however china's GDP increased due to covid threatening throwing US off the top spot which is why US done the QE to add in fresh printed money to bump up the GDP to stay at top.
US wont want to lose the top spot even it if means inflating the dollar and then tweaking the FOREX rate of yuan to look like china is less each time.
these next 5 years will be interesting though.
in the end it wont matter if its UK, US china or some syndicate of numerous nations using a whole new metric.
bitcoin wil remain as a extra option away from that game
