User:elmanchez approached me on telegram asking to buy my btc using his paypal fund
This is a big mistake: Telegram is scammer's paradise with instant name changes and the possibility to delete the other user's chat history.
I asked him to send his btc wallet from btc talk PM to prove his ID, which he did
That's a smart thing to do.
Now he is denying everything, saying I got scammed by a imposter.
That would be my assumption too. I'd like to verify the PM.
Also, if you are okay to share the PM with me then feel free to forward the PM to me. I need to see the original PM.
Forwarding a PM doesn't prove authenticity.
There are 2 methods:
1. Report the PM to Admin and ask him to confirm here. Hilariousandco has done that before.
2. Change your password, share your account with someone
trusted, have him verify the PM, and change your password again. I've confirmed a PM by this method for a user before. If you do this, by all means,
stake an address first.
he and i use localbitcoin wallet, which doesnt show up in blockchain, all internal transfer without fees
That's another mistake, if there was no real Bitcoin transaction and you can't prove the accusation, maybe localbitcoins can help you.
There have been cases in which a Bitcointalk account got compromised, and the attacker only used it to scam by PM. @elmanchez: can you check
https://bitcointalk.org/myips.php to see if anything is wrong?
