Do you have the data of the person to whom you sent the private address on the unknown person's email?
I want the email of the unknown person, his name, does he have an account on BitcoinTalk, when was the last time he logged in to the platform, and how did you get his email
I can see that you are very curious to get your money back but you need to chill and get something doing if you can. Many of us here had lost money from ignorance and we keeping learning everyday to be more conscious about investment that we don't have idea about. I can see that you want this info so bad but you need to say bye to the past and prepare for what the future has for you.
Good luck in your findings 👍
Just as @Lucius said, it's obvious for sure that OP is yet to wake up from his deep sleep in realizing that his money is way gone. He's should be grateful that his credulity didn't cost him a huge sum, for there are some persons that lost thousands of dollars to scammer but later moved on with their life so OP should follow suit and stop this 3years of ranting.
