Most nations are still monetarily and militarily subservient tribute states to the US. There is however a growing alliance of nations increasingly openly challenging US military and monetary hegemony. Since Roman times if not before monetary and military hegemony have usually gone together...along with dominance in trade. The US gained global dominance post WW2 and after the fall of the Berlin Wall that dominance transformed into unopposed global hegemony.

But today China is now challenging US monetary and military hegemony- building up a stronger military and increasingly aligning with nationed sanctioned out of the USD SWIFT trade payments system. China is now too important in global trade for the US to sanction or exclude directly- when the US tried to impose tariffs China responded by cutting off the supply of rare earths that the US needs for its military and high tech manufacturing.

There is a widespread and tragic denial in the west of the powerful position China now occupies in global trade. It is hard for US Exceptionalists to understand let alone accept how China has come to enjoy such a dominant position because they do not understand the central importance of governments in the creation of the wealth of nations...they seem blind to the repeated, numerous and continued projections of power the US government has orchestrated during its time of global dominance.

China is very unlikely to adopt Bitcoin for trade payments- it has already built its CBDC and the CIPS and mBridge digital trade payments platforms which provide trade payments outside of the USD/SWIFT network. As the USD/SWIFT protocol declines the Chinese protocols become increasingly important.

No major nation can now afford not to trade with China- including the US. The era of US hegemony is waning.

As the US empire declines Bitcoin is likely to be a useful neutral safe haven asset but international trade is now so strongly dominated by China it is hard to see Bitcoin being used for trade payments in a major way. Bitcoin might be more useful as a reserve for central banks wanting neutrality from US and Chinese spheres and protocols and if enough neutral nations central banks come to hold Bitcoin it could possibly be used for trade payments between them.
