To what extent will the economic war (between the US and China) affect its future impact on the bitcoin?
Will these countries resort to bitcoin to maintain their economic strength? And avoid economic sanctions among them?
Will Bitcoin succeed in maintaining its strength and stability as it is not under central authority?
I really don't see a favourable direct correlation between economic war and bitcoin price.
Bitcoin in its current form is still too small to be used as an economic weapon between such big economies as China and the U.S.
As both trade blows, international investors would divert their portfolio to low volatility (perceived) safe assets, such as gold, Japanese Yen and the Swiss Franc.
A portion of that might actually be diverted away from BTC, diminishing liquidity, but as a marginal fraction.
Bitcoin's lack of central authority is what gives it its resilience, but at the same time prevents its stability. Nothing to do with adoption or externalities. Its pure supply and demand.
