Do you really trust online bitcoin casinos you play at?
I think all lost in casino, except the owner.
Trust is not gained by the result you get from the casino but as what Rhavar said it is all about provably fairness where you can verify the outcome.
If all people thinks like you, I believe there will be no trusted casino because you will only trust a casino where you won some money.
We do not need to trust the house, as long as the gambling site has been so famous among gamblers.
Just try to make profits using some strategies which there are many players already shares,
It's true that the owner is who have the biggest profits, because he has the site but several players ever beat the house and get profits too, even though not many people can do.
