this is a common thing if you find it on telegram, even i get very many invites from groups like that. well, what i can say, it's better to learn on your own about trading, because everyone will have their own pattern once they get used to it.
a lot of people try to follow other people's way of trading, as was the case with that chatbox, but when it doesn't go as expected, they start blaming the person who gave the signal. whereas, the person who gives the signal only gives his prediction and analysis, he can quickly change it according to his ability, whereas the person who tries to follow him will not be able to change it because they are not used to making their own decisions. however, many people learn on social media or youtube, but people still suggest to study it yourself, and adapt it to your strategy.
