Thisisgil, I'm trying something a little bit different. This time, the buckets all have different thresholds: red has BTC0.04, green has BTC0.05, and blue has BTC0.065. This should balance the game -- there shouldn't be long periods with red at BTC0, because the expected minimum value for each bucket is very close.

That is, 42% of 0.04 is very close to 33% of 0.05, which is very close to 25% of 0.065.

To make the numbers nice and round, I would prefer to set the thresholds at: red = 0.05, green = 0.06, blue = 0.08. This would be a nice simplification to make. But let it be as it is for now. We'll see how this goes.

Folks, let me know what you think. Thanks for playing!
