In October,a stranger added me and pulled me into a stock exchange chatting group named “Jian Ping Exchange group”,in which teacher taught lessons and analyzed stock market.Since I also invested in stock,I bought some shares recommended and earned a little. About 3 days later, Yang Jianping said that he had been joining in the competition for 3 month and entered the top several. He also set up a livestreaming room. But we needed to get the ticket by registering accounts. After half of month later, saying that the market was volatile, he recommended us the crude oil trading on FuTong . I followed and withdrew 300000 RMB form stock market to trade. At first, I did make some profits, but not as exaggerated as expected. But since November 5, I have made continuous losses. I deposited 300000 RMB in total and there was only 20000 RMB left in the account. I wanted to make a withdrawal, while the customer service refused by the reason of upgrading and told me to follow the teacher, which I felt queer.
