Always better to use your own undertanding and knowledge about the game and just use those kinds of signals as track of potential outcome but never to entrust your fate with it.
Curiously, I have been in some of these groups, most of them because they have entered me on Telegram without my consent and just out of curiosity I have checked their predictions , some are immensely random, other times I have seen that other groups put more coherent things, but since most of the groups are in sports that I do not Know very well, nor their Stars, it does not give me a reason to trust , in fact they seem too dangerous to trust with our money, much less pay Subscriptions.
I was in one of the groups for a long time, where the influencer did not even hide his identity. He gave a lot of advice, signals, and called for specific actions, guaranteeing success. And over time, I realized what he was really doing.
Of course, he advertised paid subscriptions to his closed chats, but the whole point is that in fact he himself did not have any knowledge, he just did everything he advised with confidence.
This is the key. You just need to pretend that you are confident in everything you say, and then people will believe you.
Ooh, a pretender.
This must've hurt more for those who invested money in buying those signals or those who really believed that he was a genuine signal provider. But I guess there's only one way to prove it. Once it goes wrong to the first third signals then I think exiting would be the better choice.
There are lots of people who would use this kind of strategy just to make money and that's where we should be careful. It's much better if we can just do our own analysis. That way, we won't be blaming anyone and it's not as hurtful as it is when we are just following somebody else's bet.
