Personally, a a bettor, I find it very stressful when watching the game you are betting especially if it will end up a losing bet.
If we have the same experience, how do you cope up with that problem, after all, gambling should be fun but why we have this kind of feeling that we feel disappointed when our bet loses?
What really makes it more tougher is that, it is not just one person that's playing the match and still not all of the players among the 11 players will be so good at football, some might be lazy when it comes to an extent.
I which football was like table tennis games, it would have been more easier to predict because them you will know who will win and who will lose, why? Because it's a man o man game and not a team match, although sometimes the table tennis players also fuck the game up mostly when they are so reluctant that they will win, and the other player will be so busy training him or her self.
So watching the game when the bet is placed is more sweeter than watching without any bet, why? Because those that place a bet will be talking about their bets how it going good or bad for them and you that didn't place the bet but watch might just keep quiet and watching.
