Bi-Lipschitz invariance of degree at infinity for complex algebraic sets

Let XCnX\subset\mathbb{C}^n and YCmY\subset\mathbb{C}^m be two complex algebraic sets with

dimX=dimY=d.\dim X=\dim Y=d.

Degree-at-infinity conjecture. If XX and YY are bi-Lipschitz homeomorphic at infinity, then

deg(X)=deg(Y).\operatorname{deg}(X)=\operatorname{deg}(Y).

This conjecture asks whether degree is preserved by bi-Lipschitz equivalence outside compact subsets. The source says that invariance of degree remains open, notably for affine hypersurfaces in Cn\mathbb{C}^n with n>3n>3, although several special cases are known.
