There is no gambling website with a 0% house edge because its something that they need to exist and stay existing.
A gambling website is not cheap,you have to understand that..
You are fully right about this, there are no gambling websites with an 0 percent house edge because they than simply would never make profit or money to build up their empire.
Right about that, I think that they would not even can than keep the work they have to do up, they have to pay people to make things and stay it under the control..
Without the house edge a lot of casino would disappear.
