Obama tasked the nsa with finding out during his administration. I’m assuming they found out.

Alot of wild assumptions. Have you seen anything that corroborates that? Most likely, he used a pseudo-name and was cautious about online footprint, which we can assume since he was into cryptography.. Not to mention we are also concluding that that satoshi lived in the western world. We will find out one way or another I suppose. I choose to believe he's watching things unfold from a distance. If his BTC ever moves, we can continue to speculate.
