A P2P game like Contingency does solve the problem, but it is relevant to say that every bet is only connected to 1 investor/individual. So this still limits the max profit of each bet (way) more than "traditional crowd-funded sites" (since only 1 investor will need to cover the whole bet profit) and will result into some investors having a profit and some others a loss (more randomly than normal = more variance not very attractive for investors.)
This is true, but not really... I don't think it will limit the max profit.
At the moment the reason whale holders aren't willing to invest a large amount in regular crowdfunded Bitcoin casinos is because trusting an anonymous source with 6 figures isn't safe. However, with Contingency, it kinda is -- no chance of the owner running off. The only real risk involved is the variance, which is negligible. There are plenty of early hoarders who have a couple mil that they wouldn't mind putting towards + EV.
I predict the maximum bet on Contingency will be very high because of whale investors.
Further, I think a "pooling" option in Contingency would be pretty cool. Maybe it could be done outside of Contingency, with a third Ethereum contract as the holder of CTY, kind of like a trust account between multiple investors. Haven't thought a lot about the technical side of this, but definitely interesting.
