In March 2024, Vietnamese customer service sent me daily "2024 Commodity Data Backtesting Reports," claiming, "The platform backtested a certain agricultural product trading strategy using the past three years of data, showing a 95% win rate and 20% monthly returns." They even included detailed backtesting curves and profit data. I believed them and invested 100,000 yuan, which I had saved for expanding my business. However, after just two weeks of trading, I suffered losses on five consecutive trades due to "erroneous data signals" from the platform, resulting in a total loss of 70,000 yuan! I confronted customer service, and they said, "Backtesting data only reflects the past. Market volatility in 2024 exceeded expectations, and losses are a normal risk." It was clear they were using fake backtesting reports to trick me into depositing money!
