How much BTC do I need as a bankroll to start a dice site? (Excluding development)
You can check bitvest as an example and see how much it's bankroll. Currently it has an average bankroll of 1,387
BTC.
For most of the people who want to start gambling site will afraid to invest high capital like these and also I don't think he will compete with the site like bitvest which is one of the more reputed site.Anyway I think he looks for the minimum amount to stat the dice site as per the above replies it depends on the maximum rewards on that site.
