Its complex. As China grows the number of nation states explicitly operating under its monetary hegemony- ie N.Korea, Iran, Russia already are and other non 'liberal western democracies' join them there will be some more neutral territories where Bitcoin may continue to operate. But if a US originating ban occurs the number of territories where a free market in Bitcoin can exist could become increasingly small. The EU, Britain, Canada, Australiasia and Japan and S.Korea would probably be the last to accept trade payments in CBDC Yuan and would continue to support USD hegemony, and a very likely part of such a contest would be the imposition of increasing restrictions on Bitcoin- especially private custody. If a US based ban could capture 80% plus of the Bitcoin market cap not much is left for those in the middle ground between China and 'the west'. IMO the downfall of the west is increasingly the capture of our governments by rentseeking fiat bankers- so Bitcoin could reverse that, but it seems an outside chance at best.
