I've been in some nice betting groups in the past where the tipsters were actually good. Nowdays I have the feeling everyone is trying to be a tipster (even when they are bad)
They are just doing guesses and gambling with people's money...
I also think that, it doesn't matter if they know or don't know, these people like to play and place their bets using other people's money, for that reason it seems to me quite dangerous to trust groups like that, because we don't know the trajectory of what the predictions make and we don't know what they can get away with, what I know very well is that every time they lose they say that they will recover from those, that nothing happens, etc., but it does happen in reality because when things happen they lose money are very delicate, so the excuses are superfluous, I know that losing is normal, but that is why you have a sports and betting group, so as not to lose.
Hard to trust this kind of group because they are using someone else's money.
And definitely, they will say something just to appease their clients.
But we don't know what will be their final goals on this endeavor.
Because their target is to get money as much as they can, out of these people.
These days, very hard to find a legit group of this kind, where they are very cautious of what they will suggest,
or that because they are thinking of the trust that people are giving to them.
Much better if you will do your own analysis, with this practice, you will gain more insights about the game.
I always find them as shady group since as always we can always think about if they have high chances of winning why would they share their prediction to others, there's no need for them to do that since they can get rich from the insiders they have. Much better if we just practice ourselves to learn about the league since they can learn many things about it and can get more great insights about what teams are best to bet and what are those teams are good to avoid at certain times.
