Well according to http://bitcoincharts.com/markets/currency/USD.html

Their total volume transacted is about 90 mil usd.


On the top end,
90M * 0.6% = 540,000

Since they take a fee on both sides,

540,000 * 2 = 1.08M

Where did you guys get your numbers?


And when I say making money, I mean covered their fixed and variable cost!
