Apart from mt.gox (and bitcoinica) how do the other exchanges make any money?
Intersango now charge 0.6% per transaction (I think) and in GBP they've moved 255,621GBP in the last month - this is approx 1500 GBP profit. Double this for both sides of the transaction and you have 3000GBP in 1 month. This is the second most popular exchange currently.
How can any exchange survive on this or lower (shared between all staff members and covering costs)?
I could get a job as a cleaner and earn more than this.
Are they all relying on early adoption of bitcoin?
