Bitcoin Gets a Cautious Nod From China’s Central Bank

If someone buys $1M in bitcoin, that money could easily leave the country forever, without the knowledge or control of the government.
Given that China has very strict rules on capital flow - wiring funds out of the country, currency conversion, etc - I'd be very surprised if they are not considering shutting down bitcoin exchanges in China and banning the use of bitcoin for purchases.
If China does not clamp down on bitcoin, that would be a major policy change I'm not sure China is prepared for. And I'm not sure why they would choose to change their policy in this way for bitcoin, rather than continuing to capital markets in a measured pace as they are now.
I think there's also the matter of the public ledger. An anonymized public ledger is still more information than they currently have with even the yuan about when currency is changing hands and where it is going. I think BitCoin libertarians are fooling themselves if they think the public ledger isn't a major asset to the government, who can now track money from point A to point B if it enters and leaves the BitCoin economy at an exchange endpoint.
