Ok this actually happens to my friend not so long ago, he is going on a boxing match and he will bet for the heavy favorite, then suddenly an unknown guy whisper to him, that the fight is going to be fixed and he supposedly heard it from the favorite to win, locker room, are you going to listen to that and bet for the underdog.
What's your take?
The moment you have a second thought about where you are going to put your bet, you already lost. You don't want to listen to a stranger that randomly walks towards you and say something like that, most of the time it is just a bluff or he is just making fun of you, and if he successfully get into your mind, then you are messed up. So if you are having a hard time deciding where to bet, because you have second thoughts, please don't bet your money, I'm 100% sure you are going to lose that bet.
Go to another game and place your bet on something you are sure about, so you will not regret anything you do in the end.
