[ ... ] using BTCChina to crash. Volume reported by bitcoincharts is greater than Bitstamp, Bitfinex and BTC-E together, so it could be fake.
Since about Oct/10, BTC-China's volume has been comparable to what it was in Nov 2013 (~50--60 kBTC/day).
During the Nov bubble, OKCoin was ~30 kBTC/day, Huobi ~20, MtGOX ~25, Bitstamp ~20, BTC-e ~20, Bitfinex ~5.
After the december decrees, BTC-China they lost nearly all their volume, while Huobi and OKCoin grew.
The November bubble cannot have been solely a MtGOX internal mega-pump. There is a plausible explanation for it, which is the opening of the huge Chinese mainland market of amateur speculators. That demand required huge arbitrage activity, buying hundreds of thousands of coins in the "Western" exchanges (including MtGOX) and selling them to speculators and holders in China. Arbitragers (which were probably exchange owners) must have made tons of money that month. Willy was probably the buying end of an arbitrage pump at MtGOX, the selling end being perhaps at BTC-China.
No way in hell. MtGox could not absorb hundreds of thousands of coins being taken off the market without going well in to the 10000's/BTC
It was fake money buying real BTC. Most logical explanation.
