So I was thinking, puzzle keys are not sequentially generated and masked with 0s, what if for example, for a range which is supposed to start with 1like 0x10000:0xfffff , the key generated randomly had 0x2 or 0x3 at 5th character from the right? Then Satoshi would have needed to use another key.

Example:
ae65342fff1ec7f98cade1a14fe45d0ec1778a5102b9d56cbbaa8c67f6466fda

Note, the 6 in bold, since I need my key to start with 1, I can't mask this key with leading zeros, so I would discard it and would use another one.

So don't waste your time by looking for deterministic wallet patterns, or comparing the solved keys with unsolved keys as I said and Satoshi himself said it, there is no pattern, not because we don't want people to solve them, but because we don't want them to waste their time.

What we all should focus on is the puzzles with known public keys, I'd suggest everyone to dive into the vast ocean of public keys, while we all will drown and die eventually, it will be a hell of a swim! Lol.

After seeing ten folding of the pot, I have lost my focus, I can't think throughly because now the competition has more incentive!🤣
