This investigative journalist is asking for information that isn't available anywhere. It isn't available that even the FBI themselves can't confirm who Satoshi is/are.

Why people are putting so much time on this "UNSOLVED MYSTERY"? Maybe they want increase their popularity and knowing that Satoshi has been anonymous for a very long time, they want to know more about his/her/they identity. He's asking for information that no one even knows but Satoshi only. This is absurd if you will ask me because you're asking information about somebody that nobody doesn't even know - not even the FBI. Maybe he can try browsing on the deep web or the dark web. He might find the answers there.

Nevertheless, I wish him good luck, and of course, there will be a time where he will stop asking because nobody knows what Satoshi's identity is.
