Im stuck on whitebelt, it still says 20 more matches to yellow belt... I have already played like 50 matchers. I made a new account and tried again and it wont work I need help!

Are you playing with a brother or friend on the same ip? Also not to try and backseat moderate, but this is the discussion board, not the support board.

Check the turn frames of the mod you're playing, maybe it is to fast and the system is considering it as "qi-farming", so that's why you don't get qi.
Try playing mods like aikido, taekkyon, wushu, you will for sure gain qi in these.
