In the end of this March, I was pulled into a QQ group, in which teachers gave analysis on market. I followed the guidance and made some profits. Then the teacher advised us to make diversified investment, suggesting that we trade commodities. He guaranteed that as long as we followed his guidance strictly, there would be a monthly above 90% income. Members all responded warmly and got registered. Albeit unfamiliar with it, I was motivated. I deposited 800 thousand to join in. At first, there was 1 to 2 thousand income. I thought the luck is coming. Later, he told me to transfer all fund to T+0 platform since the momentum is good. After I did so, the teacher began giving adverse recommendation, causing all my money gone. The teacher shirked the onus on the broker, claiming to take to recover losses and asking me to add fund. I deposited the only 20 thousand. But the withdrawal is yet to arrive, and the service kept hold off time.
