anyway capital controls can easily be circumvented via all kinds of accounting tricks, overinvoicing, shady money exchangers, triads and etc.. if chinese currency controls were that effective you wouldn't see property bubbles mainly driven by wealthy chinese or countries granting citizenships to chinese with at least USD 1 million in cash. Illegal capital flight is unstoppable because it's the politburo itself that's corrupt to the core and needs it. Most of the middle class families too try to emigrate for better future but their amount is small to even acknowledge it as a problem. i personally don't know the exact reason but it just seems to me some kind of regulatory movement by PBOC and manipulators are simply taking advantage of that by creating more fud... it could be be a blessing in disguise since there are so many offshore places to resume trading.. look at btce that already started CNH trading pair...
also if illegal capital really went to bitcoin, we would've had ath of at least 10,000 usd or more and not 1000 since the amount of illicit money waiting to get out of china is humongous i don't think even exchange volume would've been enough to cover that... anyway that november climb to 1000 usd was purely due to clever manipulative trades that were possible due to 0 fees... if you notice dumps are only localized if this was true panic you'd see big red candles on btce and bitstamp daily... but so far all i see tall red candles mostly on local chinese exchanges so that tells me coins are staying and it's just to create illusion of panic...
Look. China has exchange controls. Exchanging yuan for currencies outside China is restricted. For a brief time last fall, Bitcoin was a safe, easy way around those restrictions. That caused the Bitcoin runup from $100 to $1000. Then the People's Bank of China (equivalent to the U.S. Treasury plus the Fed) decided to shut that down. They issued clear guidance to that effect. Some Bitcoin enthusiasts, both inside and outside China, didn't get the message. The PBOC gradually took stronger measures. Now they're issuing direct orders to individual banks not to deal with Bitcoin, directly or indirectly.
There are still some people here fantasizing that the shutdown isn't happening. Get real.
