Example of other kind of hashes / collisions:

Code:

Priv A              : 0x73376a58
Address A          : 1HBciTzQvptaeMprAb2b7Rf7MLmKxgUxHB
HASH160 A          : b183fc47e322f0c789fe7577464300dddbaca88d
Priv B              : 0x1861323a3
Address B          : 1HBciUPdv1v93jQFSkZ7uo4yrZxxZ1x6WA
HASH160 B          : b183fc4e661efeeddeff8c2d9a52d1810d6ea606
X‑coord A          : 40f9171f3ab73d2cb2439bac4a88f60d0db14b342b22bfe01354580299fd2dcb
X‑coord B          : 40f9171939818f237426a1415c983a49a8f30b2df19a379598a794579b8f4d7e
X‑match bits        : 29 (need ≥28)
H160‑match bits    : 28 (need ≥28)

That was a collision of at least the first 28 leading bits for the H160s and the X coords. The proof is in the private keys lol.

X coord matching leading bits:
