You obviously want to farm some Telegram accounts that are linked to Bitcoin enthusiasts.... right? You make the link with this post and you know how to target people for possible scams, via Telegram?
I doubt it, Telegram usernames aren't that interesting. I got curious this morning, so I sent OP a message asking for his 11 questions. So far, no response.
(Logic says... a guy willing to risk his Telegram account for $10 ....will not be a good target for scammers.)
I don't see any risk here by just sending a message on scammer's paradise Telegram. The real risk is in phising, for some reason people keep falling for that.
