I feel like the premise of using your entire worth mimics an anime i once saw in the 2010s.
It had a second world wore you had an avatar and youd fight people to gain their worth, this in turn will affect the real world. So, if a owner of a pharmaceutical company lost big time then everything he owned would go down the drain in the real world and the winner gets giant ups in whatever gives them the wealth they own.
It had 12 episodes and ended quite well from what I could remember.
