It is better to have our personal prediction than relying on others even though they are reputed because not all things they already see, some may not. But as far as gambling is concerned, betting in sports is not difficult if we are a fan of it, we know which team we bet on and our chances of winning are higher.
Gambling is also learning something, sports betting is not all about luck but also more about analysis and this is what we need to build up. That is why I chose this because we have a huge chance unlike card games and other pure-luck-based games. But I don't say it works for everyone, not all love sports so it is impossible it works with them, the same thing with card games. But the most important thing is that we choose to gamble that we never regret especially if we lose.
To be honest, I also joined groups that talked about or even gave predictions for football and boxing betting. but the predictions sometimes don't match my thoughts. I follow the group just to see the predictions given. I don't really use the predictions given for my bets. although in some games it might seem reasonable.
What we need to know is that those who providae betting predictions are also based on simple analysis. we can do it. It's just that I will choose to bet only on matches that I really understand the teams competing.
I'm not sure predictions really help. but sometimes it gives us a reference for making bets.
