As far as I can remember the stake team was looking into the sportsbook business but probably they will make another website, not put it in here. Like primedice and stake the sportsbook would probably be a different website. However as long as it is done by the same team I am still going to use it since the sportsbook world has only a couple websites that are as trustworthy as stake so on its first day ever their sportsbook will become top 5 right away, and probably try to get into top 3 if it works without any issue. I think with the promotions and so forth they have it will be amazing.
I think it's still ok if they launch their sportsbook on a different website because those who want to gamble can visit Stake and Primedice while those who want to place bets on sports can visit their sportsbook website. If this is the case then I think they should allow people to transfer their funds instantly from one website to another since they would be all owner by the same person.
