If true and the US embraces bitcoin, then...
China could have taken the lead.
Just think about it politically.
Not dangerous, I think. But rather short sighted. VC investment is already several times higher in the USA than in China, despite the fact that most trading, and more importantly - trading innovation, e.g. no-fee trading - is happening in China.
Unlike other countries prominent in the Bitcoin economy, China has imposed foreign exchange controls in order to prevent capital flight, which is a real danger to the developing Chinese economy.
And its not just the US embracing bitcoin, its the rest of world vs China in this regard.
