Yes, GUO FU Futures is a legitimate broker. With a regulatory license from CFFEX (License Number 0315), it operates under the supervision of one of China's leading financial regulatory bodies. This ensures the firm follows legal guidelines and protects client interests, which is vital when considering a broker to trade with. However, I have noted that the firm doesn’t offer demo accounts, which could be a challenge for new traders wanting to practice before committing real funds. Despite this, the CFFEX regulation ensures that the company adheres to a high level of accountability and integrity.
