I think creating a new casino or dice website is not worth anymore nowdays, because there are so many dice sites out there. What i think is, how about bitcoin/cryptocurrency sportsbook? The competition on bitcoin sportsbook is not big and i think it's more worth than open a bitcoin casino or dice site.
I also think that there are too many online casinos that are focusing their business on the dice game, and the competition for customers between online casinos that focus on the dice game is strong, it is a good idea for casino owners to launch more online sports betting websites that accept crypto-currencies, one way to attract more customers to place bet on the site would be to give a slightly better odds among competitors.
