I just joined a fitness challenge betting game, You bet 40$ that you will hit your walking goals 5 days in a week for 6 straight weeks. If you miss it you loose all the money. Whoever reaches the end and hits all the goals splits the pot.
And after I joined it hit me, this could be done 10x better by using smart contracts and oracles and bet using cryptocurrencies.
I’m just putting it out there, if anyone wants to discuss it or even take a crack at it I’m willing to help in any way I can.
