Nunyabeezwax, you forgot to mention that the bonus is decreasing each Roll your % decrease and your bonus keep decrease except if you wagered again ans again.
I try this, and the total of Satoshi to wager don't worth the little bonus that decrease After each new roll

And wager 50 000 000 to win 100000 reward point (= 100000 sat) even if you win 47% of the bet you make, you lose 53% so.....
