Thanks for sharing your experience.
Telegram is certainly a wild west when come to scammers, they roam freely there, I cannot join a legitimate crypto group without getting some of this guys sending me PM's.
I have reached a point whenever I receive a "Hello" from some stranger I immediately block them, I used to try and make them lose time, play along a bit so I can discover their modus operandi, which always ended up being the same, either a super business opportunity I should not miss or someone needing/offering help.
A bunch of losers.
