It's simply untrue. Why you do not want to admit you charge ~5%?
Just talking about mystic "business model" and try to hide the fact that you charge 5%
because we DON'T. Would show you the formulas and the code, had it not been confidential information. Don't know how else to convince you, how does one convince someone who's refusing to listen?..
gosha, I don't care what kind of forumulas you use on your site.
The fact is that your bitcoin sell rates are ~5% lower than on exchanges Kraken, Bitstam , itbit.. That means YOU CHARGE 5% fees.
You did not provide any proof that you do not charge ~5% fee. Please provide PROOF. For example, sales screenshot at your exchange you use.
Most of your users sell bitcoins that means you sell these bitcoins on exchanges. The other part you sell to your users with some low fee, but that means you earn even more! YOU CHEATERS!
