For potential energy ( U )  you can take any plain as the zero level (origin), not necessary ground.

Length of the object is considered from that plain. 

If u consider U=0 for the plain below which the chain is hanging then the potential energy of the chain will be negative.

I might be wrong, but I think I am right. plzzz approve if i am right.
