There were many red flags during the conversation

I am a completely non-technical person. For me, there was only one: entering my private key somewhere. Unfortunately, I believed that it was actually him. It's a pity that the real Dr. Brian of London didn't reply as quickly as he did a few days ago. Then the fake one wouldn't have been able to impersonate him.

Mmmm it's necessary to assume failures, even when are ours 😜, no one real person could help you quickly as a scammer will.
