This site pays 99.9%. That's a house edge of only 0.1%.
It was inspired by others, and intended to be even simpler - as simple as possible! Just betting. That's it.
But their house edge is a full 1%, and ours is 0.1%. That's not a statistical difference of 0.9%... it is a statistical difference of 900% (10 times closer to "perfect equality"!)
There are no commissions or fees (other than Bitcoin's built-in transaction fee - there's no way to avoid that!). Deposits do not require any confirmations before being credited to your account. Most withdrawals are processed immediately.
