The FBI responded that "Satoshi could be one or more third-party individuals, and they can neither confirm nor deny their existence". This response simply means that the FBI didn't confirm or deny the existence of any records related to Satoshi Nakamoto. Unsatisfied with the response Troy is planning to push forward for the release of any information about Satoshi. So he is planning to appeal this scanty response. The agency's inability to give any valuable information about the creator of Bitcoin shows that the identity of Satoshi will continue to be a mystery. I don't know why people are putting so much time and energy into unveiling the identity of Satoshi.
It’s best if they never find out Satoshis true identity. Definitely best for Satoshi but even more so the maker behind the brilliance surely would be very intriguing to learn the identity or identities and see what they are up to now but we are not meant to find this out I don’t think. I think it will always remain a mystery.
