A person named Ma Changjiang added me and told me that he could teach me the operation on stock.He pulled me into a live-broadcasting room,in which teacher Ma Changjiang,Chen Jianfeng,Wang Jianghua and Zhang Da gave lessons by turns.They led the members to trade London Gold! The alliance of 18 thousand person were guided by four teachers.They said that they were going to do the plan of the acquisition of US-funded enterprises 500%.They had 3 billion RMB and needed another 2 billion RMB.They claimed to profit the remaining 2 billion by the 3 billion.By the teachers’ urge,I opened an account in Gsgold and deposited my years of savings of 400,000 yuan.The administrator told me to follow the teacher’s instruction and send the screenshot after each operation.Following the teacher,I made a lot of profits.I asked the administrator to add fund.The teacher said that he was too tired after watching the market.The market volatility made my position closed ,causing great losses!
