Probably some VIP API for whale clients who are running bots. I doubt BTCChina is faking its data, it's the most legit Chinese exchange.
How did you come to this conclusion?
I'm a chinese, and i can tell you that there is no legit Bitcoin Exchange in China. The so-called legitimate that is only on the surface of illusion by people, this is why china ban bitcoin everyday, in fact that the gov is going to ban bitcoin exchange not bitcoin self.
I dont think the trading volume is fake, china people are rich and a lot of investors..
You are wrong, all trading volume of CNY markets are not true.
There is more speculators than investors in chinese bitcoiner
