I'd rather keep my bitcoins now consider how much I paid for them. I also studied the protocol and made a big bet with my career, so far so good. I'm playing my cards in this very difficult battle
Anyone who's sitting on a large pile of money is possibly doing themselves a disservice if they don't move it into a few other areas while the going's good. I'd never abandon crypto but retirement in particular is about hedging, preserving and nurturing which means having a significant chunk in boring options too.
