A few days ago, a person PM me on Telegram (...)
This is how the story starts and I can tell you that it will end badly for one of the two person involved in it, care to guess to whom? Cease all communications with such user, block it and report as spam/scam. Then take it as a lesson learnt - There are no free lunches[1] in life and such approaches are one of the many ways that people all over the world get scammed daily.

https://en.wikipedia.org/wiki/No_free_lunch_theoremI wonder why some people are so free to communicate with individuals they don't know; it's a very risky discussion where they might reveal details about their assets and the wallet they use. It doesn't even make sense to reply to a stranger because people who fall victim to scams like this know they will be scammed by the end of the conversation.
To prevent scams, one should avoid every stranger and never welcome any conversation. Every stranger is a potential suspect, and it is only scammers who are so inquisitive about the details of one's assets and wallet.
