In reality, neither coordinate is negative. Both y coordinates are points on the secp256k1 curve, which is defined modulo p, and so there are no negative coordinates, as anything negative simply loops round mod p and becomes positive again. And so we use even and odd to differentiate the two y coordinates.

Both points have the same X, and different Y
One of this points is positive (x,y), and another is negative (x,-y)
If we add this points with each other we get zero.
So how to define which coordinate is negative and which is positive? Any solution? Advices?
Thank you!
