Choosing casino is more important than choosing a game.
I'd be of the same opinion. This is a better factor when you gamble which can give you a peace of mind. Casinos that's protecting their reputation can always be trusted and you don't have to worry of how being fair they are because most of the time, they are.
Even sports betting can be manipulated. Even before the game starts, they already have a winner.
I think every game can be manipulated if they want to, so I can't say which is most fair. I depends on the fairness of people.
I've watched documentaries about match fixing with sports betting. But with crypto casinos, do you really think that they'll do that? I haven't heard a crypto casino that's ever been involved with that activity. The traditional online casinos, actually they have the records of it.
