Bitcoin being prepped as reserve currency.
I've now heard 2 podcasts make the case, the Whitney Webb one is particularly good.
The case they're making is that USD remains as currency while bitcoin and stablecoins serve as the underlying commodity along the same lines as the petrodollar.
Currently it's being used to gobble up US debt and treasuries as an alternative bolt-hole to export inflation, mostly across North & S American fintechs, something like $130B and climbing.
