The NSA had the capability, and the motivation. How plausible is this theory?
There's also the anagram
I AM A HOST TO NSA OK
And this paper from 1996: How to make a mint: The Cryptography of Anonymous Electronic Cash, Laurie Law, Susan Sabett, Jerry Solinas, NSA Office of Information Security Research and Technology, Cryptology Division, https://groups.csail.mit.edu/mac/classes/6.805/articles/money/nsamint/nsamint.htm
Points to consider:
- How easily could a real "Satoshi Nakamoto", working alone, perform the tasks which mainstream Bitcoin history attributes to him?
- How many vaguely-similar-to-founding-Bitcoin things are known to have been done by reclusive/secretive loners?
- How similar is "secretly founding Bitcoin" to known or reasonably suspected operations done by the NSA, or similar intel agencies?
- Why would NSA management sign off on a pseudonym that was such a convenient anagram?
- Given some of the history - https://en.wikipedia.org/wiki/Satoshi_Nakamoto#Characteristi... - why aren't you asking "What if GCHQ is Satoshi Nakamoto?".
- How useful is Bitcoin, really, for the Western intelligence community? Vs. various "former Communist Block" countries.
