Huobi's volume is +/- twice as big as the other 16 exchanges combined!
Including all the other major exchanges + smaller ones!

Almost all the Chinese are trading at Huobi!

Volume:

96,000 of traded bitcoins located on Chinese exchanges (not taking into account the Chinese traders on non-Chinese exchanges!)
41,000 outside China

+/- 60% of bitcoins are located in China.

If China dumps, the price will crash HARD!
