I am sorry to pee on your parade,but this idea is not as good as it seems
let me explain: there are so many dice sites on the market nowadays,it is pretty stacked with both old,trusted sites
like Primedice,Bitsler,Justdice etc. and the new upstarts that want to get their fair share of the market
do not start a dice site unless you are sure you can market it properly and you have something new,exclusive to offer
usual low bankroll primitive script sites will not live,you wil lsimply spend time and effort promoting and building it
think twice
There is also a news that Rollin.io site is closing or looking for a new owner. They are looking for a new owner because the way I understand it, some big rollers has been playing there and winning big. So if the OP is really keen on this idea, he needs to have a big bankroll to prevent something that happened to Rollin.
