Thats weird I have never heard of a gambling site / game that has 0% house
edge. I guess their form of revenue would be advertisements then? Just seems odd
and would be afraid to deposit or win to much that they wouldn't pay.
No doubt that there could be sites which have 0% house edge even though it will be minimal but thats not the issue the issue is how do they now get money to fund their operations and infrastructures, advertisement etc. Because from the look of it without money coming in from this source then its definitely coming from another source which is unknown to many of us. So the issue of trust sets-in.
Although we have a good winning chances in a gambling site that has no house edge, I think we will hesitate to play it and in fact how much the investor put their money when they have no advantage. Investors want to ensure profit so that would not really succeed.
