I'm theorizing about a potentially great game if I'm right in that it can be made fair to play.
So essentially you take a Casino's bankroll and let the users guess if within 30 seconds their bankroll with go up (call) or down (put). Let's say this Casino has a house edge of 1%, so since it's more likely to win by calling the player will receive 99.5% profit if he calls and wins, but if he puts and wins he gets a 100.5% profit. You can use the Casino's normal bankroll for this, a separate bankroll is not needed. Say if somebody tries to cheat by losing on purpose 1 BTC and then calls the bankroll with another 1 BTC, he will end up losing .5%.
Do you guys think this is a good idea, and is it a game you would like to play?
Quick and partially finished mockup for what the interface of such a game might look like:
