Then the bigger ones are Jintai, Nanzheng and Daotong.
The bigger the futures company, the higher the handling fee, but the service and channels are also good, at least there will be no card bill problem.
I recommend you to go to a large regular futures company that cooperates with futures companies, such as Jiangsu Xinjinhong Investment Company. You can open an account in a large futures company like Hongye with a lower handling fee and enjoy the same services and channels, as well as trading advice and first-hand information.
