This is the crux of the Yard-sale model. In a free market, one person ends up with all of the wealth – completely by chance.

Looks like the monopoly game. It is inevitable. This effect is the following:

When you lose, the maximum amount you can wager goes down. So you can't win back what you lost in one coin flip.

When you win, the maximum amount you can wager goes up. So you could potentially lose more than what you won in the first game.

Besides I like the work done on the interface to make it interactive 👍
