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?
Actually fixing matches are not just in boxing matches, many sports games are manipulated for the benefit of a person. even big games have been involved in fixing scores / fixing matches, especially boxing matches that are not highlighted in television, of course there will be prone of manipulation. If someone offers me a fixing match in boxing game, I'll see who sells it first, whether he is trustworthy or not.
