That's why people who are truly experts in analyzing and predicting won't tell the crowd. They prefer to save or share it with the people closest to them so they still have privacy and can do other things. They also don't want any reputation because according to them, it doesn't mean anything and is just a reputation that can be lost in an instant. These are the ones who can make money from gambling and even use it to meet their daily needs.
Yes, they might lose because of mistakes in analyzing, and that is still within reasonable limits because their analysis is also not perfect. And when they bet, they place it secretly and don't tell anyone because they don't want to hear that anyone will blame them because their analysis is wrong.
That's a very good argument.
Anyone selling you data or any kind of signal or whatever, clearly is not making money from their thing.
Otherwise they would just keep quiet and continue making money with it.
The fact is that we humans find it easier to find something wrong than finding something right. So if an assumed expert gives his analysis and the game fails, people would pay more attention to that (maybe because it hurts) than if they had a win. I think that is why some people don’t like to share their analysis. What I believe makes someone good at analysis is if they win more than they lose, let’s say the least of 6 wins out of 10 games. But still don’t trust anyone because the analysis you listen to and make your decision with could be the one that fails, you just never know until you lose money.
