BTC puzzle 66 :13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so
so far found :13zb18UKn2awwhpshZUjhLXZMcGbzC5soJ

the prefix and suffix nearly same

And what is the relation between an address and a private key? There are trillions of trillions of addresses in 66 bit range, there could be millions of such addresses there, let me save you a few months of useless pursuit, stop looking for addresses, instead focus on subtracting from the known public keys to reduce their bit range.

Why do you guys think up to 120 have been solved every 5 puzzle apart? Because solving exposed public key puzzles is much more easier than brute forcing other ones.

I mean what else do you guys need? Just subtract 2^124 from the #125 public key and you'd have reduced 2/3 of #125 from it.

Ok let me explain, imagine #125 as number 750, if we subtract 500 (2^124, half of 2^125 or in our example 2^125 = 1000) if we subtract 500 from 750 we'd have 250, now all we have to do is to figure out what number is closest to our 250 (which we don't know it's exact value) and try to subtract that guessed number from our 1/3 of #125 puzzle, and the rest would be easy.

Focus only on subtraction, stop wasting your time on randomly searching for unknown keys! 😉

Good luck and happy hunting!
