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.
The OP looks like he's trying to take down other groups to get a lot of attention on the group he's marketing LOL. even now i have not found a single telegram group that is truly honest about trading, on average it just ends up being a scam and many people offer services in the group. stay away from any kind of telegram group is the wisest thing.
