Not only for gambling no one should depend in others for anything. own research is a best way to success. But if op joins a group, he can get some ideas from there and match his personal predictions with them. But betting according to predictions from any group is not a smart person's job. So always do your own research and then bet according to your predictions. In this case, confidence and chances of winning will be more
That's right. They have to find their own way to have analytical skills. After all, if they have good analysis, they don't need to rely on the group, and maybe they can become more skilled to make money from gambling. Joining several prediction groups can make him learn many things, and he can also ask how to analyze properly and correctly so that he can start trying it himself and testing it until he can analyze it well. Learning betting analysis is difficult because we have to collect more information from various sources. But it's worth doing, especially if we want to be a bettor in sports betting.

Not so. Different groups use different ways to get profit. A part of groups use(sometimes they even develop themselves) special software to search difference between bookies odds. Some groups searching online broadcast to catch moment when the teams scores and the bookie hasn`t change the odds. Some groups analyze matches. Of course they can combine these ways, but mostly they use one or two of them - it is difficult enough to bet in different ways.
That makes it difficult for people to learn the analysis used by each group because they have different methods, so those of us who want to learn it need more time. And it will depend on how we choose the ways we will study. We can also combine each of these methods to find better ways. We will only find out by continuing to test it through betting on many matches to find out what needs to be improved.
