This is important, because bitcoin is a bigger threat to a weakening fiat currency than to a strengthening one. China is still a long ways to go before their monetary and fiscal policy isn't as loose as a 13 year old Thai prostitute's vagina, but they are "tightening" and the U.S. is still "loosening." China's CB is also buying massive quantities of gold, and they encourage their citizens to purchase gold. So in some ways, Bitcoin is less of a threat to them and more of a threat to the dollar. They may not mind it so much since it may hurt their "enemy" more than it hurts them.
The enemy of my enemy is my friend.
