You are thinking “how much fiat can I get for my BTC?” You and I are not the same.
Discussion
FIAT is for now the measurement of the buying power that you have. When (and IF) bitcoin will be the dominant measurement we can talk about measure in Bitcoin. But right now Fiat is very important for the measurement.
Or do you not care about the buying power? Is bitcoin not money for you?
No I don’t care about buying power, I care about storage power. Specifically storing time / energy up for a future generation where all the energy in the world will not be able to mine more than 1 BTC in a year (ca 2097).
