But here's the catch, I don't have a "source" or "contact", I simply use a program I created that tracks suspicious bets, it uses AI and real time trackers. If someone is offering to "sell" you fixed info, it's usually a scam.
I have made over $2,000,000 with a starting balance of $11,000. I did not need to sell anything. The only problem is when the sportsbooks limit you or confiscate winnings. But that's what I call a strategic loss. For every $10,000 confiscated I make an average of $100,000+ profit.
A lot of people posting the same question:
"Do fixed matches exist?"

Of course they do!!! But you're not going to find it on the clearnet

You're better off tracking large bets placed on low tier matches or rapid odds drops. This can easily be done with some API's and python code.
It may really exist but not in this forum. Also I do assume that those wjo are really having access with fixed matches won't need to encourage or share the signals to other people simply because they are winning more than enough already. Yes I find this suspiscious actually. If it is that easy to enter a fixed match signal group then games would be ruined by complaints. Same reason why such thing should be hidden to big exposure from other gamblers. Imagine that majority of gamblers knows the outcome of the match; who'd bet on the contrary? Also, personally, I have no ideologies of cheating over other people who are betting some of their properties just to get this exclusivity but ends up with nothing in return.
