BTC China volume
Where is Huobi?
In terms of volume for Chinese exchanges, it's OKCoin, then BTCChina, and then Huobi.
I believe they are getting their OKCoin volume purely from the international market spot exchange, which is the lowest volume of all 6 of OKCoin's BTC orderbooks. Their international exchange isn't even Chinese-based - it's a Singapore company and is meant to serve customers in every country.
If they're including Bitfinex, they need to include 796 and OKCoin futures markets.
Since when is Bittrex considered a Bitcoin exchange? They only trade altcoins.
This infographic is a joke. Whoever made it is clueless and doesn't actually know anything about any of these exchanges, besides maybe Bitstamp.
Thanks everybody for your comments, We've totally depended on the sources we mentioned at the end of the infographic, may be they have some wrong numbers and information, Please anyone sees a wrong information here, tell us and provide a source for the right one and we'll edit it in the infographic immediately.
And about the title, yes, i think it should be "Cryptocurrencies exchanges" not bitcoin, as we've mentioned some altcoins exchanges.
Here are the current 24hr volumes for the 3 most liquid exchanges (for the past 24hrs...I'm sure you can find averages, but I'm not going to look for them myself):
OKCoin.cn orderbook: 195,104 BTC
OKCoin.com orderbook: 79,953 BTC
OKCoin.com futures orderbook (leveraged): 574,920 BTC
BTCChina main orderbook: 213,614 BTC
Huobi main orderbook: 125,240 BTC
796.com also probably has nearly as much volume, but that's leveraged up to 50x. You need to make a decision whether or not to include leverage in the equation - Bitfinex offers leverage on their main orderbook, so they'd pretty much be out entirely if we're not including leveraged orderbooks.
Huobi and some of the other Chinese exchanges also have some subsidiaries like BitVC, which likely are also in the top 10. I didn't really go into detail here and some of these exchanges may have other orderbooks with extra volume, too - just trying to lead this in the right direction, not do everything myself.
