I was also going to mention the table but anyway there's a bunch of casinos that have their own exchange it's just that they rarely get any promotion or visibility.
IMO the reason why they're not that common on most casinos is because there's a risk that it won't be profitable since their rates are always higher compared to regular exchanges and that amount of money is probably better spent on other things like marketing or promotions.
Especially for beginners, it’s common to expect a negative outcome that it might be not working in the future and can only be a waste of time and money. That is why some operators have chose to stick with casinos first and improve all that needs to be improved, and adopt more casinos marketing and promotions because gamblers will surely make it a big thing for them.
Creating an exchange within their platform will cost them a lot, they will need to hire more people to focus on this and yes this is why many site don’t want this one. They can just focus on their casino and stay in the competition, many gamblers prefer not to trade their coins/tokens though when they are playing they wanted to stick on it and withdraw the safe crypto to their own personally wallet. Haven’t seen yet a gambling site have this option, maybe its far from reality.
Doesnt really cost that much but rather it might really be adding up more hassle and lots of things to consider before adding up some instant or exchange swap sites or feature into their platform.
Im not sure on how much it would be, therefore it might be that expensive or not but just like the rest been mentioning that there are ones who do have their mini-exchange or swap
feature but only limited into few coins but as im not surprised that fees wont really be that something to be cheap and it is really that much sensible if you do pull off those coins
you do have and convert it out into external platforms if you are really that serious on exchanging it which does cause cheaper.
