With the fees they charge, and the volume on the exchange, I don't see how they couldn't be making a profit? Of course I'm not a business guy, might be something I'm not thinking of.
If they were making profit, I'd assume they would make a press release. They would want the business world know.
No. If they're making a killing and released it to the public, there would be a clamor for lower fees.
Privately owned profitable businesses don't usually go trumpeting to the world how wildly profitable they are. That is just inviting competition. Kind of dumb.
