Iran is now a tribute state to China. it is only with China purchasing Irans oil and providing payment in manufactured goods that Iran has been able to continue as a viable economy despite the US sanctions excluding it from the USD/SWIFT trade payments network. Chinas alternative trade payments routes are still based on fiat (Yuan) and in some cases CBDC Yuan....CIPS and mBridge. Because China is now the dominant global productive economy in manufactured goods and commodities China is developing alternatives to the legacy USD/petrodollar hegemny that the USA has execised over the world sine WW2. China is not likely to encourage Bitcoin but rather appears determined to impose its own fiat monetary hegemony similar to how the USA did. MoE dominance is the basis of fiat monetary power projection - it has been for SWIFT/petrodollar and it will likely be for the CBDC Yuan China operates. Government has always been a significant factor in wealth of nations and Bitcoin does not necessarily change that.
