If Bitcoin became the global money standard who do you think who benefit or left

Hey Let’s play with one of these scenario I am having in my mind these is What If and who for our Economy
Hypothetically whether through by massive Bitcoin adoption or just by failing fiat currency or just somehow slow and steady change

where Bitcoin becomes the world’s main way of measuring value.

Imagine price for everything like the Gas, Groceries, Loans, even big International Deals If all listed in BTC or sats instead of our Traditional dollars or euros

Just going this out for discussion like
1)Who ends up better off in this world?
Like the Long-term HODLers?
Or the Countries that had jumped in early?
Or the Exporters?
Poorer nations that maybe got left behind before?

2) And who gets hurts the most Will it be ? Government?
Central bank? Or Countries that rely on inflation to keep things running?

3)Does these make the global economy more fair or will it widen the gap between those who got in early & those who did not?
4)What will happen to all the debt country & people already have in fiat? Could that default become the new normal ?
5) Would the government actually starting to mine the Bitcoin Just to keep up?
