When I get the profit and transfer to HBC for $ 8, but when I sell HBC to withdraw the BTC is $ 5. if i receive 1000$ profit, i only withdraw 700$


?
NOT FAIR
If the transfer price is $ 8, the loan price is $ 8 or more meaningless. Because the price of the Internal exchanger is only $ 5-5.5
Transfer should be equal to the price Internal Exchanger
