Lucky or unlucky, it's not subject
Subject is Ecc
And sha256, where claim one-way working
But these all from hex to wif or pubkey then pubkey to address, there are some conversation process, and same creating tx also based on conversation,
These all process are based on math calculation
Add multiplayer substraction division, all used
If you write python, c or use bsgs or kangaroo, all based math,
Universe law is what ever step taken have footprint, which can be reversed, now see ECC
Start from 1 and end at N (....4141)
N also called 0
Mean before N-1 is called 1 = -1 same pubkey with direction of y
Now understand it's game of 0 to 1 and 1 to 0
Definitely reverse or footprint available, inside math
Example proof, when universe created, scientist send jamesweb telescope to find footprint of universe, definitely it's available
Ecc is very small portion, by math you can find, no need gpu only CPU could work,
First math based kangaroo used at CPU and take 100 bit rewards
But don't stick your mind with gpu, use math in other form at CPU definitely 160th pubkey rewards could be yours
