Even satoshi Nakamoto will open his identity on the public the price will only boost if he is a well-known identity and influential in the real world. But if it turns out to be just an ordinary one this will not affect to bitcoin price. But I doubt he will come up in the open for he might be targeted by mainstream media and banking haters of bitcoin. And even government will take a share from his hold bitcoin.
The only thing that matters about him is the 1.2% bitcoins he holds in his wallet which could crash bit coin economy if released at once.
The correct number is 5.89% which when priced at $6000/BTC makes his net worth a whopping $6 billion.
