I'm conducting a survey to determine the actual profitability of the popular exchanges.
Does anyone have any idea of what the volume is for these exchanges? What these exchanges make weekly or monthly and how we could find out?
you can observe the volume on sites themselves , and on sites like bitcoinwisdom.
Judging on the fact that most of the time exchanges have multi-milion traffic, their profit is huge.
and not just huge, but large enough that they can influence the price by keeping the profits in bitcoin or selling it for fiat.
funny when u think about it.
Should be glad there are now more exchanges vs MtGox monopoly a year ago.
