I also got two certificates. You can choose a good securities company. Generally, their subsidiaries are futures companies, and then your double certificate is useful. My personal suggestion is to do securities, because the stock market is the mainstream and the salary is quite good. If you are a futures trader, you can't do it. It's hard to do it. Many people don't like to play with it. I am a broker of a securities company, and sometimes I do some futures business by the way. The above is my personal experience, and I hope it can help you.
