0% house edge is risky, isn't it?
Ehhh...no.
What is the risk of 0% HE? Do you understand the concept? The only risk is the variance, but in the long run the risk tends to 0.
Risky for who? For the user or for the house?
The risk of 0 house edge for the site is the fact that they will not make a profit in the long run, is like trying to make money by flipping a coin, do a simulation with 10 million flips and you will see how it ends 50/50 or close to that number. Even if the event is random they follow a behavior.
But as Poker Player say, the risk is the variance, make 100 bets, with 50% chance of winning, if most of them lose then double the bet, and that way you can win in the long run against the house.
Right, I thought I was the only user noticing a problem.
