The casino which create a token didn't look good at the moment since the price of it dumps and some people got pissed about those condition. And since This casino is well established already I don't think its really necessary for them to create those since this maybe could just add some hassle to their team especially when many people ask for a pump or even find some good exchange for their token to be listed. So overall Stake is already in its best shape even if they don't have tokens exist on the market.
Casino tokens do well for a time because unlike most altcoins at least there is a real business behind the coin which gives confidence to the investors to invest, trade and hold those coins, but the weakness of those coins are the casinos themselves, if the casino begins to present some problems then those tokens eventually crash, so I do not think it is recommended for any casino which is already successful to release their own token as they risk that happening to them and put a stain on their immaculate reputation.
