that would be cool, I love the idea of a market for house edge...
You could also do a market for variance: Have a slider for people to choose what their own personal "maximum bet" is (in percentage of bankroll). All of that gets pooled together to be the site's max bet, and returns are proportional to that. Someone that wants low variance can choose 0.1%, someone more aggressive can choose 1% (and someone that wants to really gamble can go > house edge%). This is a way to have investors have a decentralized vote on what the minimum bet should be.
Investors would be basically running their own dice site! Investors set their personal edge AND the variance!
A big +1 to this!!!
This is a great idea. I like investor-chooses-their-max-profit than I like the market for edge. I think the 1% edge is this website's defining feature and it would be a mistake to change it.
But by implementing investor-chosen max profit we would arrive at the "optimal" max profit per roll (the sum of everyone's personal max profit setting), in the sense that it is the consensus of all the investors. This may be more or less than 1%. In fact, it would be fascinating to watch it go up and down as whale(s) come in and out.
This is the first idea I've read that seems worthy enough to change the format of the site.
