Well I would suggest to avoid any such group because majorly this groups will fits in those 5 pointers. The basic purpose of this group is just that only to get as many as members and keep advertising other groups. And also I do not find majorly their research is full proof and you will even lose good amount of money by following those signals.
I get the feeling yeah. I was in a group before which uinfortunatly closed and there where making pretty good signals and much news. It was a group which was more adversted by person to person talk.
All other telegram / discord groups i found are just scam shit.
