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.
It isn`t only analyze. It is using different software, sometimes it is about cheating. Not everybody likes it. I think that we can study to analyze in such groups, but i don`t think that we can study how to develop some software. The same time it is difficult to use 2-3 types of software and analyze matches the same moment. But it is all about details. The main idea is that there are such real groups and it is possible to get stable profit from these groups, but we mustn`t give our money for every group we see.
