although there are telegram groups that provide good information for signaling a coin, it's best to study it yourself. no matter how good the offer is, sometimes people will sue them when they get a loss from the signal. to be honest, there are lots of telegram groups like this one, only, we don't know if it's a scam group or not, and even when it's free, most of them just provide information on pure speculation without data. personally, I really avoid such groups.
One of the reasons why I don't stay in groups like this is because even though I can give good information, there are telegram users who can be humans or bots that send you messages greeting you and offering to put money on a certain platform, and when you tell them that you are not interested in it, the person or bot becomes very intense, and it is really annoying, sometimes they want to inquire about us and it is not good, currently there are all types of contact, be it with people or bots, we don't know if there is a virus involved and they get information.
