To be honest I would never use your exchange the fees are ridiculous, why would anyone pay $500 more for one Bitcoin if they can buy it also on another website with good reputation. Your website also shows a Btc price that does not even come close to the real price.
Your price: 6774$
Real price: 6265$
We don`t know any website where you can buy btc with real market price, Do you? Don`t forget for credit card fees, site maintenance cost, salary and profit. Why somebody should sell you btc for real price? where is profit?
