Learn to read some information while doing your research
That's what most people actually don't want to do and for that reason rely on these signal groups to serve them advice on a golden plate. It's utterly stupid how people think, but they are the reason these groups exist.
If everyone did its own research these groups wouldn't pop up as frequently as they do in current times. Some groups have like 100k followers which just shows how little people care about potential abuse.
All they want is to catch the next pump and they'll keep trying till they hit bank at some point. If you repeatedly bet on something, you'll be right at least once eventually. They are way better off blindly investing themselves.
