My conclusion: stay. The blockchain itself will be the killer app upon which all other apps and bitcoins' fiat value will depend.]
While I was reading your post I was thinking about this myself. This is exactly what i'm thinking.
Since bitcoin can technically "live forever" then I guess it is inevitable that it will reach 0 at some point. But that is probably waaay WAY in the future.
Lets hope they figure out how to stop ageing or something.
