The word challenging can have either a positive or negative connotation. It has a negative when there's little reward for accomplishing something difficult but has a positive connotation when the accomplishment is expected to be rewarding monetarily or personally satisfying. A challenge itself is not positive or negative, it's the circumstance of the challenge that determines that.

Monetarily, no one.
