Yeah I agree with you, finding a legit betting group could actually seem impossible because there are lot of groups which offers betting games but at last the person will end up losing out, what most betting groups normally do is to get some wining bets pictures from other platform and post it on there own group to lure people coming to subscribe with them knowing fully well that most people always love easy ways of getting something, which has actually lead to many victims of wrong betting group.
So the best way is just focusing on the little knowledge someone can predict for himself because in the game of betting nobody is perfect one could Actually improve and figure out a strategy that could actually favor him instead of relying on betting group.
Good point and that's really happening there are betting groups that posted other prediction especially those winning prediction to allure those people/gambler who always aiming for quick benefits, gambler who don't want to spend time to do research and deeper study with the kind of sports that they wanted to place their bets.
Most of the time if not always, they are victims of so-called expert prediction which lead them to lose more instead of the money that they only use for betting but the payment for betting group that's no guarantee that will convert something for them.
I recently came across a group on telegram where the owner post free sports predictions every day, since the channel was completely free to subscribe to,( I mean he charges no fees at all, there is no vip of any kind), and for the fact that I've become very busy this days that I hardly have time to analyze games and find good ones to bet on, I decided to give the channel a try with very little amount of money, I started copying and betting on all the games the channel owner posts on the channel, I did it for about one week and hard my initial deposit more than doubled, I was really excited and was planning to put more money in but unfortunately, all of a sudden, all his games started losing, it continued to lose until I lost all the profit I previously made including my capital, I felt really disappointed and haven't played any of the guy's predictions again, even though he is still posting constantly ..
What am I saying, this things can't be relied on, even those who get games from vip channels, there is still no guarantee of consistent winning in the long term , this is why it's not advisable to subscribe to such cus it's usually not worth it in the long run .
