If they don't do anything then provably that there's nothing will happen even if they offer this option since there are lots of casino doing great promotion which is really appealing to gamblers. Hopefully they became competitive and launch something attractive which their potential gamblers to enjoy.
I think they should focus first on what they have. They just recently launched in the forum, so they cannot rush things when their platform is not popular yet. Adding a sportsbook might be too costly for a new casino. Instead of doing that, they should focus more on the marketing side to introduce the casino. Once it becomes more popular and the budget is enough, that’s the time to add a sportsbook.
