Trading with an unregulated broker like Guotai Junan Futures poses several risks. The most significant is the lack of investor protection. Regulatory bodies like the CSRC, ASIC, or FCA provide oversight to ensure brokers adhere to fair trading practices, safeguard client funds, and maintain transparency in operations. Without such protections, there is a higher risk of fraud, manipulation, or unfair practices. Additionally, unregulated brokers may not offer compensation schemes, making it difficult for traders to recover funds in case of bankruptcy or fraud. Therefore, when choosing a broker, it is essential to ensure they are properly regulated to minimize these risks.
