Is there a way to determine if a point on the curve is even or odd?

if i have a satoshi each time that i see that question...

Sadly there is no way to determine if a point in the curve is odd or even, also there is no way to determine if bit in any position is 1 o 0 that would totally break ECDSA

I already try a lot of things to try to anwser that question, but none of them works and actually i really give up that way, my recomendation is not lose time in that topic (Unless you are full cryptographer with wide knowledge in that field)

Welcome to the club by the way.

Hello 👋 all.
If we divide an odd number X by 2, as a result we will have a remainder of X.5, is it also impossible to determine whether there is a remainder at this point?.
