That is why you make the deal on-site so we can validate that the product was received if a dispute is opened.
Are you telling me we should believe that someone used your BTCMiddleMan website for transacting 28 Bitcoins last week, like it is written in one single TrustPilot review by some anon guy Matt H.?
Sorry but I find that hard to believe and it looks like a fake review to me, and I guess you can't prove this transaction even happened using your website.
Did a 28 BTC transaction through BTCMiddleMan.com and had no issues! Thank you!
