I think match fixing really existed on if not all maybe some sports worldwide including combat sports. Match fixing is really annoying on our part as a gambler as it could turn against our bets right on the spot. But that will of course decrease teams reputation and other involved parties.
Yes I think we could tell it depending on the game type. It's sad to say that something is rigged and already planned ahead in terms of sports, but as a gambler of the same genre the best thing to do is to adjust. You can chose whether to still bet on it or let it passed and wait for other games. You can chose whether you want to risk or better me preserve the capital that you have. It's an accountability of the gambler and I think that's the beauty of it.
