When I see to it that most of the time when everyone has the knowledge in trading, you keep in trusting him and give your ETH and Private Key to hold the wallet. I was being fooled already and it seems that the coins are in the wallet already. It is a biggest decision that I've ever made and the biggest lesson that I've ever learned.
My experience is not on one but there are several coins which i used to trade to increase my amount of btc i make profit but the mistake i made was selling it immediately after reaching my goal , what i realised now is it's better to put stop loss rather than selling it away because you could easily make more profit or control your loss.
