What? Satoshi's last publicly known email was on April, 2011 to Gavin [0], stating the following:
"I wish you wouldn’t keep talking about me as a mysterious shadowy figure, the press just turns that into a pirate currency angle. Maybe instead make it about the open source project and give more credit to your dev contributors; it helps motivate them."
Also, let's not forget, it took BTC ~1.5 years to gain any amount of traction at all. Nakamoto was in for a long run and his sudden disappearance is always going to be mysterious
