Talking to avoid scam telegram groups, but you offered anyone to join your groups since you claimed it's legit group.
Yes, we should avoid all groups including you.
I thought this thread is a serious warning not to join signal or scam group but looking at the link that OP shared, I think its different from the message of the title. Its really need to avoid any unfamiliar group, its better to join a group that works with the project you are planning to invest with, just don’t join on any signal group because its too risky and its useless, you will just lose money if you follow their tips.
