Why do you think Satoshi disappeared?

Did he see the potential for bitcoin and decide to separate himself from the project?

Or maybe was a prolific criminal hacker on some government’s radar and he’s now sitting in prison?

Or perhaps he didn’t disappear voluntarily. Maybe he passed away due to an illness, or sudden accident? Does anyone think there’s a chance Satoshi was killed?

With Satoshi’s disappearance, how does that fit in with the theory that he’s actually a group of people and not one guy? A group suddenly deciding to cutoff communication, and no part of Satoshi has really reappeared in public?

Did he lose his keys and leave out of ultimate shame?
