It would be interesting to compare "retiring on bitcoin' numbers in the vid below with @JJG projections.

In the vid: if you want to retire in 2025, it basically does not matter as age 25-65 has a narrow range of 10.13-10.71 btc needed to retire this year.
Of note: if you are 35 and want to retire in 2050 (at 60 y.o), you need to get to "just" 0.79 btc; if you are 45 and want to retire in 2040, you'll need 1.41btc.
