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.
