That's why the only thing I bet on from home(online) is sports betting, the house edge maybe a little bit higher but you are getting an insurance that you are not getting cheated.
I think that most of the online casinos cheat, why? Because no one can detect if they cheat or not.
They can cheat and also to be considered a legitment business.
I would avoid using any of those online casino unless it's a dice game that can prove provably fair with Hash.
