anything wrong with offering 1.56% house edge? (higher than 1%, but lower than satoshi dice's 1.9%.) and matching kelly.
No, but why would anyone play your 1.56% edge game when there are reputable 1% edge games available?
Almost nobody plays satoshidice any more, because they don't want to pay double the house edge of the other games. Why put yourself at a disadvantage?
Well, it's not the same dice site as everyone else. It's my 64 blocks game, the winner gets 63x. It would be a bit odd to offer 63.36x what you bet to the winner. I just thought it was easier to compute 63/64.
You can only bet on a per block basis, so that's 1.56% each.
It will be a unique game. For the next two weeks. Until someone else copies the concept. Then I can and probably will have to drop the house edge.
Nobody will gamble at higher than 1% edge because they want the best chances they can at winning money.
