Do not worry much. In Europe soon all highrollers will sue casinos, so casinos will not accept them...
Stable (= not expecting changes soon and without history of rip offs) and not shaving apart of North america (Bovada, 5dimes, SIA) is probably just bet365 and 1xbet. Unibet for example is still very good with me, but after they did the retroactive changes, it is hard to recommend them. And they convert quite badly in Germany to stay on topic (but I think they have some problem with German tracker).
