1st - they are still buggy, today lost 10k points cuz bets just dissapeared after lots of votes on a some guy's stream with 500+ viewers. Bet on win 10k points, he won but I lost my points like anyone else no matter the amount of points they beted.

Awesome idea!
but.. If nobody bets on the opposite you will never win points.
If you are a small streamer its hard to get your (for example) 10 viewers to activate their points and start betting + you are punished for being good player :D
I maen.. I played on Hardcore to find challenge so my battles are not 1 sided and ppl will have reason to bet for win and lose but... couldnt find such challange.
Had less than 20 loses for the whole game when I did every possible fight (Ultimate club fully passed).

So... I guess you should consider adding some points in the prize pool. Like if there are atlest 5 bets or more idk... (keep in mind the game doesnt really have much viewers in some random guy's stream like me :D) for only 1 of the possibilities and they predict correctly - give them like between 1 and 10% bonus points just to encourag them :)

Or if its possible... create "pool" of lost points on the current stream for all the time. So when all bets are on win but the streamer actually loses the fight or vice versa those point are added to the " stream pool" And then after having points in this pool (maybe above some number) give them as rewards like explained above.

I feel I need to say it one more time. Viewers in small streams dont really like to bet on the losing vote expecially when its obvious. And all of them being correct all the time is still leading to no rewards and so no fun with this interaction for the chat (viewers).
