US Central Bank has to resolve a dying economy with a hyperinflationary monetary policy (cf cryptohayes.medium.com/pumping-iron-a…)
Or risk international confidence via a sovereign default.
2/
China wants CNY to be the world's choice currency so it doesn't have to yield to US's monetary policy. BRI, and institutionalising CNY denominated debt - recall USD war debt funding that entrenched USD as the world reserve currency.

Where then does BTC come into play? Forget the role of governing bodies, but look international trade and project financing. Corporates like tesla, apple, microsoft hold massive import/export shares.
