What if we could divide by bits the range all the way to 1 bit? All keys are the modular inverse of the first key start point.
Thanks to Quite the Contrary for teaching me how to do this

How do you propose we divide by bits down to 1? And who taught you what exactly, the youtube you meant?
As I see it, it's just 7 divided in half
He just subtracted 7 from N and divided the result by 2, and as I see it, it's just 15 divided in half, because dividing 7 in half would give you 3.5 where you could see 3 as the first character and that .5 as a huge number, here is the example :
3fffffffffffffffffffffffffffffffaeabb739abd2280eeff497a3340d9052
As you see, the .5 which is a fraction has turned to something different, this is the beauty of big numbers combined with elliptic curves.😉
