Honestly, you'll find many more scam casinos online than you would in Las Vegas, but I think it's much easier to stay away from them.

Here online you will find many scams as well as many reputable casinos whose legit reviews are available online. If you talk about stake, jackclub, dueltbit, rollbit etc casinos then most of them are licensed by good companies and are well reputable.
And besides, another simple thing here is that before you gamble, you should pay attention to which games provider the game is from. Because most casinos use games from companies like Pragmatic Play and Evolution, which are not actually manipulated.
