yeah basically bigger bankroll bigger chance to avoid bankruptcy , i agree the most important thing to start run dice gambling site are the big bankroll that could cover big winning for many times.
3,000 btc to start maybe more than enough as bankroll tu build a solid dice site?
good bankroll is very important. however, it is also very important to have a good marketing strategy to attract customers to come and play. i have seen a lot of the app/gambling site dont even have a single bet in a day and soon it is closed down.
