Interesting thought.
I've actually made a gradual shift over time.

I don't hope to "cash out" anymore. At one point I figured I would come back to fiat. Now my goal is to stay in some type of digital currency. If Bitcoin changes or a new coin takes over, I will need to move with the flow.

This is a scary thought though because it puts me at huge risk if the whole market collapses. I think crypto as a whole is anti-fragile so I'm betting on some form pulling through.
