Why do people lose money in derivatives?

Why do individuals often end up losing money when investing in derivatives? Could it be due to a lack of understanding about the complexities and risks involved? Or is it perhaps because they are too greedy, hoping to make quick profits without properly researching or managing their investments? Is it possible that some investors are influenced by false promises or misleading information from brokers or financial advisors? Additionally, could market volatility and unexpected events also contribute to these losses? Understanding these factors might help investors avoid similar pitfalls in the future.
