The Bitcoin official site has informed you that you can buy BTC via exchanges listed on the Howtobuybitcoins.info website.
And there are 7 exchanges listed for you to buy BTC in China, but among them, only three are Chinese, and the one Asia Nexgen has less than 100 BTC volume (per day?), out of date, right?
In fact, China has the most BTC exchanges in the world, among which, the following 10 listed in the table are the best with most trading volumes:
|Exchanges||24-hr Trade Volume||English Support||Mobile Friendly||RMB Deposit||LTC||Other Altcoins||Notes|
|Bter||4,927.40||Yes||No||Yes||Yes||Doge, NMC, XMP, etc.||Volume only for BTC/CNY.|
|BTC38||851.80||No||No||Yes||Yes||ANC, XPM, PTS, etc.|
|796||Unknown||Yes||No||No (USD, HKD & EUR)||Yes||No||It treats BTC like stock.|
|1. Excluding 796, the total trading volume of BTC was 212,219.63 in the last 24 hours.|
|2. All the above data were collected from the 10 exchanges' official websites, at about 9:30 pm, on Dec. 27, 2013 (Beijing Time).|
Among the above 10 Chinese BTC exchanges, BTCChina and OKCoin are mobile friendly, Huobi has the most trading volume, Bter and BTC38 are available for you to deal with altcoins like BTC-E, while 796 is weird.
Excluding some other smaller exchanges which are not listed in the above table, these 10 has over 200,000 trading volume per day, more than the sum of Mtgox, Bitstamp, BTC-E and even more.
So, it's no doubt that the whole BTC market trend will be affected by these 10 Chinese exchanges deeply.
