Definitely a scammer. I tried to trade with him, said 2x $500 transactions were approved, was waiting on a third one $1400. Allegedly, it had been declined and all the money, including the two previous ones, would be refunded. I waited the regular 1-3 business days, as per the screenshot he sent (although the payments were showing as posted the next business day). He affirmed that he never withdrew the balance, but provided no further proof. Although it was an assumed risk and I was fully aware that I may be scammed, others beware, he'll try to delay everything until 24h pass and he gets another shot to double the money (I did lock the card after some time, taking a risk is one thing, being stupid is another one).
