He said someone reported and his signal group was closed, he is trying to create a new signal group. Hopefully, he will come back and send us his new group info. I also want to check if what he is saying is true or just like other scam signals.
One more thing, no one can close your group unless you violate telegram's rules, only they have the right to close or delete your group. Maybe you have spammed or scammed many people so you have encountered a large number of reports leading to the group being closed.
I also agree with you, but I think that if they report it on telegram and say that it is a scammer or a scamming group they also close them, now Telegra has a lot of security, although for me it is safer to use telegram than WhatsApp itself, too It is something very different when they say that the signals are free, it is something different and I think it is much more accessible to many. When it comes to free signals I don't say anything, because I know that it is an incentive that some take to share what they know, in fact if they are very curious they can create a community that can generate very good signals, because by sharing knowledge, they can be done big things.
Whatsapp is also a popular messaging app just like telegram but it's not usually the one that is being used when it comes to crypto related talks so I think it is more safer to use since it was not infested yet by the scammers.
There are many groups that offers free signals other than the paid ones so I don't know why you said it is different. Other signals are more accessible because they are still there but the signals offered by the op are now more. It's sad that its life span is only short. If ever the op came back here, it will be better if he private the links only for his own safety and to assure that only those who are truly interested will join.
