What would you do if Satoshi's coins move?

I've heard a lot of people who reference the original Satoshi fortune held in bitcoin that hasn't been spent, transferred, or moved since inception. Some conspiracy theorists have pointed to it as a Cryptography bounty from the CIA for proof of vulnerability in the system, which would mean a larger threat to RSA and public key cryptography. Some say Satoshi is already dead (or at least the wallet key is lost or broken) or else how could he resist taking profit?

So, a 2 part question: If the coins move, what do you think will be the outcome for Bitcoin? And what will your immediate steps be to safe guard and protect your hodl?
