Seems you realy do not understand))
I talk about brutforce (you know what is this?) and you are trying to impose a search for an incomprehensible pubkey that I can look for years.
No I am talking about finding the private key for ANY pubkey which matches a particular criteria: one where the first 60 bits are zero, so that it will take on average 2^60 operations to find it.
I am not talking that programm can found public key with criteria like 192 leading zeros or something. Read carefully!
I told that programm can brutforce keys to find public key with speed 2.2Ph on xeon.
if you know public key than YES program can found private key from this public key after some time...
But this time depends only how far the starting private key from the desired..
