But man, even these low-reward puzzles are impossible to crack. Either there’s no explanation, it’s straight-up wrong, or it’s just unsolvable.

Interesting code. I feel like all these puzzles goin’ around are unsolvable. Especially if nobody’s cracked it in seven whole years. That’s wack.

We all know very well that every puzzle can be solved, and it's only due to the vastness of their scope that we end up saying they’re unsolvable! In my opinion, linear search is pointless and only the search steps themselves should be considered. Although in this forum, no one fully shares their methods, according to a previous user, they claimed to have completely searched the 60-bit space. However, it seems they’re not being honest and may not have searched at all. I hope to solve puzzle 71 soon, and if the user had asked for help, I will assist them when I do.
Hehe well let see . Hope puzzle 71 solved before btc go to $300k
Bcoz if it go over it the solver will always say brute force 😅.
I believe this whole hash have some kind of usable bias to guide to the key .. weather frequency bias or somekind of statiscal bias in bit collision 😅. But it is hard to discover yet 🙃
