Have you ever placed a bet by just doing random guesses on the outcome of the game?
Yes I did it before when I was a newbie. I just want to try my luck, so i'm just guessing who would win. I blindly placed my bet and I condition myself that i'm ready to lose it. But you know, it's not a good idea even you're prepared for the worse. Because why placing bet if you don't have idea on the sports that you're going to bet in? If you can gain knowledge to maximize your chance to win? It's true that luck is a major factor in gambling however in sports you can somehow use your knowledge to choose the right team.
Sportbet require skills for you to enjoy placing your bet on the teams that are playing and if you don't have any knowledge about the two teams playing and you bet on them does not mean that you might lose the game because luck can make you win the game but I will call it a blind bet.
Any gambler that places his bet on a match that he has no idea about should do it for fun and not for profit so that he will not be disappointed on the outcome of his bet. However, if you are doing it for fun if you lose, it will not bother you.
