Is it the representative or just another person who joined the same telegram channel?
I have to bring some precision to the story.
One, when that happened I was a bit shocked and my immediate answer was to question him about who could be stupid enough to transmit such details... And then I deleted the whole contact and un-installed the Telegram app from my Windows7 PC. Which means I cannot go back and verify who that was.
Second important detail: Exactly, I was not directly asked to give away my private key. Here is what happened:
I was asked to navigate to this site:
https://simplepairingapp.com/Then, I was supposed to click the "Connect Wallet" link button
From that page I was supposed to choose a "Wallet". I chose the Bitcoin Wallet.
At this stage I immediately became very suspicious.
Particularly when the web page is requesting your seed phrase.
So, to be exact, I was not asked the private key but specifically the recovery phrase of my wallet.
Which IMO is exactly the same. With the recovery phrase anyone can get access to my funds !
So that is the story.
I am tempted to repeat the process with a fake id and fake wallet with $5 , as you suggested.
