I have even seen many betting on even friendly matches. When there were tournaments, yes, many used to bet on which team will win. Many have been much happier with what they won betting on the correct team. Even teams which were not up to the mark, have won and made people trust on them to bet more on upcoming tournaments. Its everywhere man. Those who have opportunity to gamble, they do gamble and those who are just exposed to betting on matches where they can, they do bet so. As long as its entertaining and thrilling yes, nothing wrong in it so.
That's how gamblers be like, in every opportunity to place their bets, they will come and bet on it, even friendly matches. They will take part in it and try to win.
Not just by predicting which team will win but also those available odds that they knew, they will take advantage in hope to win decently.
No wrong with that, as there are many exposed gamblers on whatever sides of sport betting who will continue to support and find
their luck within this industry.
