Wow 50% how stupid or desperate are these people in those countries? Even people buying btc with hacked paypal accounts wont pay that much.
Why stupid? The price in IRR is higher than price in Europe (EUR/GBP) or in USA (USD). So my offer is simple: I can sell them BTC cheaper, 50% discount but in IRR.
So if BTC costs 600,000,000.00 IRR I'm willing to sell it for 300,000,000.00 IRR.
Then they can sell it with localbitcoins and earn 50%.
So I earn 50% and they earn 50%.
No one is stupid, this is a business.
