While reading through this entire thread, I came across two intriguing individuals:
satoshi_rising – Everyone knows about him and how he tenfolded the puzzle prize in 2017.
retired_coder – He supposedly owns the private keys to three puzzle challenges.
This got me thinking—what if these two are actually the same person?
I carefully analyzed all of retired_coder’s posts and noticed something else interesting. There was a user, k3ntINA, who attempted to predict Puzzle 67’s private key using a so-called "magic trick" (which, from a cryptographic standpoint, makes no sense).
However, by sheer coincidence, he correctly predicted the first few hex digits (462, 463) of Puzzle 67.
This shocked retired_coder, who then reacted to it in a humorous way, as if trying to downplay the prediction. Here’s his post about k3ntINA:
You are my hero! We need more magic circles!

It seemed like he wanted to ensure that nobody took the prediction seriously.
This makes me wonder—could it be that he actually knows all the private keys to every puzzle?
My above post is also related to this prediction. The question is:
does Puzzle 67 start with the hex '46' ?He was talking about the 66th puzzle, and even then after it was solved.
