Cold storage vs. ETFs

At 46 years old and minimal retirement savings so far, I've been absorbing alot of people's perspectives on the best route for achieving my goals in a 15-yearish window. I'm unlikely to live to see hyperbitcoinization or the collapse of the fiat system. It seems like the most rational, reasonable approach would be to heavy index funds along with some Bitcoin ETFs. Safe and uncomplicated.

I'm going with real Bitcoin in cold storage.

Why? Because it stirs something in me. It makes me feel like I'm part of a revolution that the world desperately needs, rather than simply riding it's coattails to get my basic needs met. It feels more like living life rather than just prolonging it. That to me is worth some extra risk and effort.
