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.
At this point in time, any new casino focusing their attention so much on dice game will not get anything. There are so many other platforms offering a whole lot better and for what it is worth, I do not expect someone coming up with something lesser will be able to make any impact or receive a positive result.
It might be worth something if you end up creating something unique and probably adding more games to it which could be attractive, except that, it would be a fruitless effort as we have seen a whole lot of them coming and disappearing in a short time.
