What is the normal volume of this exchange? I'm guessing it's something less than 1000BTC. So how could something that does a tiny volume suddenly do 80,000BTC volume? I would think it to be technically impossible. There simply wouldn't be the liquidity, deposit/withdraw processing, exchange engine, order book depth, etc to do it. I mean I could see it maybe GROWING to that amount over a month or so, but not overnight.
They were steady at 1000+, then this happened 3 days ago:https://bitcointalk.org/index.php?topic=264812.msg3237296#msg3237296
Either they are manipulating their API stream or China has discovered the BTC.
