the thing i about the is group allow to network with other crypto enthusiasts and know what they are thinking in current situation. thanks for making this list of groups
Here most of them are telegram channel not groups. you will get much news rather discussion. there are groups also that you can use for your discussion or analysis.
if you browse you will find that channels have chat groups also. where members chat with each other and share new projects. They discuss about the project and thus the credibility of that project comes out.
