Sportsbetting is another game of luck. Things are not going to be better when you think that you are experienced enough. I'll give you some example of this. You can check a site that host tipster competition monthly and you could see that most tipster that has set up thread in this forum are actually deep in red currently
One of the problem of sports betting is you will win just a little.
It is like they always want you to bet on those teams that have the lower percentage to win.
They give high odds to those teams to make you bet which gives them the percentage to profit from you.
It is a gamble as always. Who would pick the underdog team with a little odds where you wont even feel the prize for it.
So still it is risky.
