Currencies have their little local monopolies. Globally traded goods like commodities, gold, bitcoin, and that sort of stuff is mostly priced in the largest and most liquid global currency: USD. Unless or until something grows large enough to flip it.

Our little currency is globally traded just fine.

Would love to see any place anywhere -- real or virtual -- where Bitcoin has the tiniest local monopoly. It would at least be a very interesting scientific curiosity to study. The only place I can see is zaps on nostr. Spend says earn sats. What's the transaction volume on that.
