I think you need time included in your equation. Getting to infinity could take hundreds (maybe thousands) of years but you only have a tiny subset of the timeline. So in your finite amount of time, will there be something better to store your wealth in? Maybe? I've not seen it on my timeline.

Pivoting to your aversion to risk, that may be where you need to determine if you would rather forgo the opportunity cost of having "too much" bitcoin in exchange for feeling safe or stable.
