But are you able to captalise on any fixed matches? I highly doubt it.

There are a ton of scammers who fake having fixed matches information but at the end of the day what they're trying to do is just get you to pay them a share of any profits you make. They do this until you lose - in which case, of course, they just stop contacting you.

I've personally seen these scams happen in the past and it's all a game of numbers. The more people they reach out to, the more likely someone is going to win and think that the matches are actually fixed.
