I consider Bitcoin to be money and money to be an asset. I take your point, but I don't think it matters much if we use those words slightly differently.

This exercise is about purchasing power, so I could have done it in terms of current Bitcoin value. The simulator provides both values. Maybe it would have been better to say that the model implies Bitcoin's purchasing power "should be" 15x what it currently is.

What I'm trying to figure out (as much for myself as for anyone else) is how should I be treating this thing. How much can I expect the sats I'm saving to buy when I need them in the future? How hard should I work for a given amount of sats?
