Don't bet on games with house edge if you want to be a successful gambler, that's the main recipe to success. Slots, roulette and even dice with a house edge of 1% , you will still lose, lower house edge better chance to stay longer in gambling but in the long run you will still loss.
Reality is necessary, we will only know it if we understand what our real chances, that's why I focus on sports betting now as I think there's no house edge in this kind of game, some may say there is but I say there's none.
How do you explain your point that there is no house edge in sports betting?
That means that if you bet on two completely opposite outcomes at the same time, as long as there is no third choice, you do not risk anything? That, however, is not the case.
I think every bookie has to have a house edge. Otherwise, they would lose their liquid assets very quickly.
