Our house edge is 0%. PumpFight is not a house based platform, players are betting against each other. But platform's profits should still be generated somehow. So the commission is taken as a percentage from only the winning pool (and not on every bet placed). The commission is taken into account inside the displayed "potential profits" of each bet. Thus, a player knows the exact potential outcome of a winning trade, including the fees of the platform, before the bet is even placed.
I was referring to that by 'house commission'. This type of commission rate gives guaranteed profits to the casinos from each round. The winner side is getting 166% amount when the bet amount is same on both sides. So, the commission rate is around 17% from each round. Everyone would address this commission rate as high.
