I've been using the MRG Premiere app for a few days. It worked well until certain stocks were blocked (only in one direction) because the odds were too favorable for me. They don't mind taking your money but cheat to prevent you from winning easily. Fortunately, my full withdrawal was respected. The app has been uninstalled.

The website of MRG Premiere can no longer be opened, and there is very little information on the Internet, as if it never existed. But on the bright side, I don't see anyone claiming to be scammed.
