It doesn't change anything. Do you see any strong impact happen to Ethereum when people know who is the creator of that coin? Nothing right so maybe the same thing will happen to Bitcoin and people will just continue to do their thing especially on investment.

The only changes will happen there is people will stop discussing any related to his identity and people will just continue to speculate about its future.

Maybe best for you not to think deeply about his identity since you can't get any accurate answer with that since up by now people are still speculating about him and there's so many threads the same like this created because people are just curious about him.
