China takes too much credit for bitcoin moves. At one time 98% of the trades were done on exchanges in China. This was due to no fees and wash trading. They made it look as though everything was done in China when it was false.

Now that there's a trading fee in China, real stats are available. The most trades occur on Bitfinex (10.41%). The highest in China is OKCoin (8.12%)

In order: Bitfinex, OKCoin, Kraken, BTC-e, Bitstamp, GDAX, BTCC, Poloniex.
