agree, even if still require to own and think in fiat... The ideal would be to have 100% bitcoin in every moment, so to spend bitcoin everytime we need to buy goods and services. At this point is easier to solve the "hodl or spend-and-replace?" dilemma, cause is just a matter of time preferences and monthly income/expenses.

A softer and most applicable version of this solution is to own just a little amount of fiat specifically for expenses that would be to inefficient to be conducted in bitcoin, with merchants that want fiat.
