That depends on what kind of platform you make. Formal platforms don't give kickbacks, and those informal platforms are normal. If this is a simple rebate, I'm afraid I'll have to eat your losses, so it's basically impossible for you to make money.

Regular foreign exchange dealers, the funds invested by investors are all in the international market, and no one wants to eat your losses. But the black platform is different. What they do is the inner disk, which is the gambling disk. Funds will not flow into the market, but will only flow within their platforms. You earn, they lose. Do you think they'll let you make money?
