Not just bitcoin. Chinese money is buying whatever assets they can get their hands on; purchases of real estate in Canada alone last year significantly exceeded the entire market capitalization of bitcoin.

That site has some numbers as far as exchanges go but there really isn't any place you can go to see a definitive trading volume number.
You also can't rely on volume numbers for any exchange that offers trading at 0% fees. The big three exchanges in China all have inflated volume numbers.
You could also look at value of Bitcoin transacted on the blockchain itself. Transaction volume had been steadily growing until it hit the current theoretical maximum in the last half of this year. The thing to look for now is increasing total transaction value. Hopefully the blocksize gets raised soon so total transactions can continue to grow again.
The Chinese are running away from RMB and buying bitcoin, Venezuelans are running away from Bolivares into Bitcoin. And to a lesser extent some Indians are escaping the Rupee.
It'll be really interesting to see how governments try to deal with decentralized currencies if they really take off. Governments lose a lot of control when they can't control money.
