You still calculate your net worth in Fiat if “price” is your wealth metric.

Thus you assume it either always goes up, or goes down then up (higher than your average purchase price).

This means you are right under your set of circumstances in both cases if the goal is to have a Bitcoin price higher than your average fiat price.

But what happens if the fiat price goes down, and keeps going down?

Or goes down, then stays flat and doesn’t even follow monetary inflation and price inflation?

You do not address this, even though I understand you believe “Bitcoin game theory” will prevail…
