Hello scammer... uhmm (cough cough) I meant bitcoin mixer, so let me understand the modus operandi: you want people here to load bitcoins to your mixing system and then they get a Unitaco voucher which they exchange for "clean" bitcoins.
So which escrow do you use on this forum? Obviously if someone wants to mix or "clean" 5 BTC (for example) then you should deposit a refundable escrow of 5 BTC to one of the reputable mods here which they can hold until you deliver the mixed coins, right? Or do you really really really think people should simply send you unescrowed coins and wait for you to mix them? In your dreams.
