OP is a newbie account and his first post is very vague and I find it suspicious. My experience from telegram has taught me to regard these kind of posts as scam attempt. These kind of scams are common on telegram…the OP makes a comment on the a group complaining he’s got some bitcoins locked in a wallet or exchange and he needs someone to help him withdraw promising to share his bitcoins with the person.
Yeah, its very old technique some random one will contact and even provide the proof they have numbers in the wallet but the website is completely fake and the numbers are just generated by the scammer himself, but in that case they generally ask some amount as deposit to release all of it but with OP there is no relevant information provided.
They also go ahead to send dms to anyone they can find, fortunately bitcointalk doesn’t allow newbies to send dms.
Actually newbies can send PMs too but the receiver decides whether they allow PM from newbies or don't want to in the personal message settings.
