Do I have to use the demo account? Can I just start with a real account?

As for the question you asked, we checked the official website of GemForex and found this broker providing links both for Demo Account and Real Account. But whether you can just use the Real Account while stepping over Demo Account, we recommend that you ask the official customer services directly for a more accurate answer.
