What you say is very true, something that is available on the internet is of course paid if we want information about predictions then we have to pay for it even though the predictions given are not a guarantee of winning the bet and it would be better for us to analyze the bet we are going to play ourselves and If what we do is we can win our bet, of course this is very enjoyable and if we lose, we make our own mistakes in analyzing, but if we use a betting prediction service and we can't win the bet, of course this will be very sad because we lost because of other people's predictions.
Not all things are paid and not all paid are good. And not all of the paid predictions are premium. Usually, if there are some that are for free, just take time to read and think if you'd follow it or not.
It's true that even you pay for a premium, it is not guaranteed and that's why if there are means of having those predictions for free if you don't want your own, take the free.
But, if you can have your own for free as well, why not enhance and cultivate your predicting skills through various research? You'll benefit from it and not just about profiting but also by improving yourself.
