We can imagine a future, when the US, China, Japan, India all have 1 BTC reserves as a national asset, when the price of BTC has stabilized at about $1M. Perhaps then we can still use BTC as a means of payment daily, by 1 satoshi = 1 cent...
However, this means that the war of money printing will end, instead, it is possible that countries will actively manipulate mining. Gold reserves store will become the nation's centralized BTC mining factories ^^
And ... 1 country has just been lent 1,000 BTC by the World Bank to recover the economy after the COVID-x9 pandemic
