hi guys!
im a rly noob in this game
where can i see, how much points i need to achieve the next belt?
when fights are over, there is shown always, how much tc the player earns and how much games he has to play till the next belt.
but i never see these things at my own wins

There is a belt guide in the second post of this thread - http://forum.toribash.com/showthread.php?t=105823 that will tell you how many fights you need to get to the next belt

and your qi is shown in the shop page here - http://forum.toribash.com/tori.php

I assume you need to win 20 battles to get the yellow belt, right?

Nope. Games played is enough.

yup see i suck at this game but im still a blackbelt

mosier that link only tells me, how much fights i need generally.
but i wanna know, how much i have/need at the moment.
where do i see my personal stats with belt and rank?

No. The link that Mosier gave you - http://forum.toribash.com/tori.php - shows how much fights you have at the moment. Your Qi: xxxx

And how do i earn TC from fights?

ur personal stats just click on shop u'll see ur qi and tc then find stats while ur there

By winning the fights ash
