I agree with you that win or good result depends on how we learn to make predictions and analysis of each match we are betting on.
Usually people who join and believe in online courses or betting groups are those who are not confident in their own abilities and really want to get instant predictions without any complicated learning or research.
People like this in the long run will only receive bad luck and also ruin in gambling.
It's about finding value to secure wins. However, for those who join sports betting channels with the belief that they'll win by blindly following, they may not have a sustainable future in sports betting. Relying too much on others doesn't ensure consistency. Even if they are winning initially, it doesn't guarantee ongoing success. It's known that once a tipster achieves a good winning record, the subscription fee tends to increase. Subscribers may not be aware that the tipster might have just had a lucky streak.
Moreover, those who subscribe will only spend more money without any guarantee of winning and losses will automatically increase due to paying for subscriptions to betting groups and also paying bets in the matches being bet on.
But recently I have seen quite number of betting groups stating that they will only ask for payment if the predictions given are successful and they also provide referral links for every gambler who wants to bet.
From what I found, I concluded that people who own groups like this not only take advantage by asking for rewards from predictions but also affiliate.
As time goes by, people who gamble by relying on groups like this will realize that they should not trust easily and it is better to teach themselves how to predict results so they can be more experienced and get results consistently because they are betting based on knowledge, not subscribing to betting predictions.
