Its largely impossible to fund "organic decentralized" prediction markets because the vast majority of money that goes into them is "dumb money" and there will always be sharp money that takes their cut, and has substantially more funds. Betting markets are zero sum, so the smarter participants is always going to absorb the entire bankroll of the dumber participants over time..
The closest thing to what you describe were BTC dice games, which is kind decentralized, but prediction markets are impossible, some smart guy is always going to be there to make a more accurate fair on a market and eat all the liquidity from the little guys.
Isn't that entirely the point? I've heard some arguments about insider trading but even there i've heard it argued that that's part of the point.
My point is that maybe federated casino where there is no casino but sort of p2p on a completely fair 50/50 dice of sorts similar to how casinos operate would be more beneficial than casinos existing with their 3% cuts and the house3% always winning.
At the very least, its possible to do so and similar to Kalshi/Polymarket I feel like its definitely possible.
I don't want to EVER touch gambling but I think its addicting and maybe it can atleast help the addicts if they are in a fair game compared to a rigged game towards the house.
