Hypothetically speaking, what if he just randomly died one day, yet no one knew, and everyone thinks he's alive still?
He used to be the most active member on this forum, then he just stopped. Maybe he had a heart attack one morning, he could have slipped down a staircase and banged his head, some guy could have dropped a rock from an airplane and it crushed him underneath, who knows?
Maybe he was an 80 year old man that, as a last resort to life, made Bitcoin, then died due to old age?
1) Why he used to be an active member of this forum? Where did you get that information?
2) What the difference if he's dead? Nothing is changed. That's the point of decentralized system.
