Outside the forum, I have been asked about WhatsApp and Telegram groups where sports betting codes are shared, I always tell anyone who ask to please share to me if they should find these such groups and websites because I will like to be a member.
I have come across many of such groups on Telegram and WhatsApp, but the thing is: Most of their games are not always accurate, as they always predicts that it is. Most of them even don't run a free predictionsgroup. All they do is run some free games, which can be correct either by luck or by coincidence, and they parade most of these their games on their channels and want people to join their paid group so that they get access to more games.
I don't always believe in such precautionsgroups, at least not 100%. There are more fake groups out there than the real ones, so you can either relay on your own predictions and then use those channels alone to crosscheck yours, if they give you any, and then you can make some shuffling in your games, but putting your 100% hope on them is not advisable.
It has been years that such services are online, but they do not always work. This is just as anyone's analysis will not always work no matter how good you are in speculation. So anyone relying on them (external sources) is only wasting their time. Some would even pay for such service which I believe is nonsense since gaming and gambling is something anyone can easily learn and get to be making the best out of without any issue. Even if the gambler is not sure of his gambling skills and could have been losing more, the best I know is for him to analyse and use external predictions to confirm his decisions. Those predictions that are however in agreement with that of the external predictions might be used for better precisions, as such only means to add another layer of possibility (increased chance) to the outcome, just like you filter yours with theirs. This is not a certainty to win though and I am not telling anyone to follow the path but I must say that I had used it before and it reduced bad gambling for me.
But now, I gamble my thing alone, and so is my gambling analysis because I do not know the reason why I would need a third party for my gambling when I can do it myself. What I do mostly is to make sure that I bet more on sports, that is the aspect I understand best and that I can easily manage for my success. And the fact that the instinct to the speculation is what I see daily, it's so easy for me to make more money even though there are also bad weeks, if not months, yet I manage the account well and it has helped me to keep going.
