In July, I opened two accounts, depositing 3,100 and 2,700 dollars respectively, and the bonus was both 750 dollars. The manager said that according to the rules of the platform, I can convert the bonus part into a balance and then withdraw the money. Then I made more than 300 hands in both accounts. Among them, I did not lock the order or everything in accordance with the platform rules. Finally the 1,500 USD could not be honored when the deposit is withdrawn. In this case,please reply me whether the platform is suspected of fraud.
