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.
