Satoshi theory? I don't really care at all if he/she's still alive or dead.
To be honest, I am proud of him because I really like his idea, which is the BTC, and it makes me admire him for inventing something that will change the lives of others. And I don't know if he's dead, people are still using his own invention, and with that, the advancement of our technologies will continue and won't meet an end.
What's my reason? I respect his decision for being anonymous from the start so obviously he wants to hide his identity or other personal things to the public, therefore, we shouldn't bother at all about him.
He's probably still alive since Bitcoin is not that old. This topic would make more sense 15 years from now. He's probably still doing whatever he can to keep his identity hidden.
Almost 10 years? Even at the 1st anniversary of bitcoin, there's a possibility that he might die. No one's immortal here.
