In "theory", sports is p2p, meaning you are playing against other people and not against the casino.
Yes, it is not like poker where you are directly getting the pot, but sportsbooks make money from the fact that you end up putting money in both sides and that is how they pay out, while it is not a must, it is usually averaging it out each other and that's how bookies make money, they are distributing the money they get from other sides to pay for the winner. Roulette is directly against the casino, and that is why it's harder to make money from that.
Hmm who said is hard to make money from roulette,I totally disagree with you,do you know how many people that's playing roulette game in a day, infact in my place roulette system game is more preferable to many than even football,that's why I raise this motion,they found roulette system so simple that it's very easy for them to make their money out of it ,so I totally disagree with you if you said this.
What kind of bet you go with roulette though? I mean single number? Red of Black or dozens number? The reason why I'm asking is that yes, I do agree with you that it could be profitable. But you really need to have a big discipline here when you are playing roulette.
Because when you got lucky and hitting those numbers, for sure you feel that it will go on until you lose and then that is the time you might want to chase more and bring back that money. So once you are in the net positive when playing roulette, you should stop. But the question is, can you quit when you are winning in this game?
