Re: How to be profitable in sports betting?

Because they had a service fee. When you wager for example $100 and if you will win you have a profit of $90. So, the $10 is their revenue.

That's wrong, most gambling sites offers a lot of odds, there are odds like 2.00 and over, so if you will keep choosing that odds, you will always get 100% or more from the amount you bet. That's what we called juice or commission in sports betting, but like I've stated, you can always do away with that.

I would like to demonstrate an example.

you can bet on brooklyn nets for 3.5 to get the odds of 2.05 and if you go on the other side, you can bet on the Lakers at -5.5 and you will get an odds of 2.05.

Betting on the underdog or going for odds above 2.00 doesn't take away the fee/juice though you're still paying a part of it.

Using a margin calculator it shows that sportsbet nearly have a 5% margin. The true odds without the juice would be 2.15~(for 2.05) and 1.86~(for 1.78)

Forget about the juice, it could varies from sportsbook to sportsbook but if you keep betting odds below 2.00, you need to increase your winning rate to make yourself profitable in the long run, and of course with proper bankroll management.

Choosing odds 2.00 and over, you just need to win at least 51% and you will be profitable, but if you go lower, like take odds 1.70 and below, you need to maintain more than 51% winning rate, I can't compute but it needs to be higher and its a tough job.
