I think you need to be mindful of keeping the max multiplier low, at least with green. If I'm not mistaken the most you can risk is going to be: `(1-MIN_MULT) * ((0.005 * BANKROLL + 1)/MAX_MULT) `, which with even the impressive bankroll you have is going to be like ~0.006 BTC with the above scheme for green, and much less for others. I'm not going to deny my mind as been brain damaged by the gambling, but that's not enough to make me flinch.
I wanted to give users as much variety at the different levels, so here's what I came up with:
edge('green', [ 145, 2, 1.8, 1.4, 1.2, 1.1, 1, 1, 0.75]) - Very safe, for a ninja that waits patiently for his bitcoins. - edge:1.000
edge('yellow': [ 777, 33.33, 12.35, 4, 2, 1.3, 1, 0.6, 0.5]) - Bit quicker, for average length gaming sessions. - edge: 1.000
edge('red': [1032, 135, 25, 9, 4, 2, 0.21, 0.2, 0.19]) - Do or die, for a loose cannon ninja with nothing left to lose. - edge 1.000
Thoughts?
I decided to tweak green a bit, to give users a higher max bet on green.
edge('green', [ 38, 5, 2.3, 1.4, 1.2, 1.1, 1, 1, 0.75]) - Very safe, for a ninja that waits patiently for his bitcoins. - edge:1.000
