You simply cannot guarantee a profit from playing dice at Bustadice. In the long term it is statistically impossible to overcome the house edge and use a casino game like this as a revenue stream. If it were possible, why would Daniel even keep this site going? Bustadice is not a charity.
It's true, overtime the losses will be so high that even if you are winning the losses is still much greater, that's the right logic to apply, why would run the site if they know that they aren't the one that's winning all the money circulating in the site. Also, does Bustadice still have their bankroll investing?
