Think about it logically for a second. The sports betting market is incredibly efficient. There are armies of analysts and sophisticated computer algorithms, and on the other side pro bettors all hustling to get an advantage. If someone truly had a foolproof system that consistently delivered those kinds of returns, they'd be making billions quietly, not peddling their secret "working method" online.
So when you see some random newbie account bragging about their off-the-charts success rate, red flags go up. It screams scam. These scammers know people want easy money and they take advantage of that greed and stupidity.
