Depends on circumstance. If I can verify the RNG directly, pretty close to 50% plus transaction costs. If I think I have an opportunity to punish obvious defection, 100% (implying a non-stochastic outcome rule). If I have no recourse in case of defection, I would not pay anything to play regardless of stated odds.
Is this really the only motivator, though? What stated percentage would you need it to say to think you’ve got a “real” 50%?
