I very often lose when I bet on friendlies... I usually bet on a win, but often the result is not in my favour... Many clubs or national teams do not make an effort in such matches, do not attach importance to them, treat them like a training session... That's why I try to avoid such bets!
The bet loses three times and you keep repeating it until you lose the answer from the friendly match. You have wasted time and money that you should not have risked in the first place. It's nice to realize that betting on friendly matches is not a good option. You will not get the sensation of a real gambling game.
If there will be a case that I really need to bet at these friendly matches, I'd rather choose the around @1.5 odds because since it's a friendly match, I doubt the underdogs will push a win against the favorites even the former will not give their all..
or it could be that friendly matches are planned so that local players feel the best when faced with high-class players, so that they are given the opportunity to score several goals in the early minutes, then end up slaughtered with crazy scores. LOL
