Ok, but what is it that makes having the public key so much easier to find the privat key ? What role does the public key play ? What is it about the public key, that helps the program find the privat key ? What does the public key tell the program, that makes is easier to find the privat key ? Does the letters and numbers of the public key have anything to say, or what is it ? Why is it not blindly when you have the public key ? What do you see, when you have the public key ?

We can do some basic arithmetic operations (blindly) with them.

But this is only useful when you know some information about the privatekey like the range ( smallest ranges are easy)

for puzzle 66 i used bsgs with i7 7500U and that took 30 min to scan all the range.
is it normal or i missed something to make my scan faster?
