Back here after a few weeks, and notice one thing.
Why Op uses NatashaOtomoski instead of Satoshi Nakamoto?
Does it increase the difficulty of the question? No.
I think a part of the key needs to be anagrammed
The entire question has 37 characters so i don't think anagram work here
That is not my point.
Since NatashaOtomoski is a clear anagram of Satoshi Nakamoto, the only clear question is whey he used it?
The answer could be, you need to use the same algorithm on the solution.
posted that awhile back
https://bitcoinexchangeguide.com/nakamoto-family-foundation-book-gets-stylometry-test/the 21Teeth could refer to the book that came out with 21pages also using a cryptogram so maybe the values given to each letter used to decipher the book title (in the link)
could be used to crack this.
NatashaOtomoski=Satoshi Nakamoto
both mentioning 21
and both using a cryptogram
