with good people like you around people keep getting scammed. People that are too good for this world don't belong on this forums. This forums is full of scammers waiting for opportunities to scam people out of their money. NEVER trust someone and NEVER send them money first (except if you know them well). Always use escrow or exchange.
I'm not worried about the coins they earn in one day, I feel sorry for the man who cheated, him come punishment for this, he punished himself.
