Via this experience, I'm sure you now know that the above is not enough reason to trade with someone without taking necessary precautions such as an escrow or other whatnots. People can successfully trasact with others for quite a while, before actually carrying out a big exit scam, they use the first few smooth transactions to build trust and after that is done, they can now pick they victim and perpetuate their exit scam, so going forward learn to take responsibility of your funds.
