In sports betting, the odds increase or decrease based on the data that bookmakers obtain every hour, minute or day or week. for example, if there is a Liverpool game against Manchester City, Manchester City, being a team with a good squad, will be seen as favorites by the bookmakers, but if at the time of announcing the squad that will play, Manchester City puts all or some of their best players on the bench, then the bookmakers will immediately lower Manchester City's odds value and it could even happen that Liverpool becomes favorite in the game, so the odds value has nothing to do with having or not have a large number of bettors

Now about this issue of groups having options for free tips and paid tips, this is not advantageous, what happens is that the guy who owns the group gives only 1 or 2 free tips and tells people that if they want more tips they must pay membership to he can send more tips and the tips he sends does not guarantee that they will be accurate and in most cases these group owners keep sending tips on games that have low odds like 1.20, honestly what is the point of people spending 80$ paying membership to receive game tips with odds of 1.20? This doesn't make any sense in my opinion, it's not profitable to bet on games with odds of 1.20

my advice is that people learn to analyze games on their own and not depend on other people, it's not a good thing to be dependent, imagine if the guy in the group who gives tips gets sick and gives up giving tips as they get people who become dependent on his tips? And how could a person consider themselves a sports bettor when they cannot analyze a game and place a bet on their own? In my opinion, people should not trust groups or advice from other people. should analyze and bet on their own
