you are talking about using bitcoin as an edge agaisnt inflation and you are considering spending it for the purpose of making small payment and you think that is not going to cause a diminish of your coin? if you are really interested in keeping bitcoin as an edge against inflation, you should consider that you are not spending it for no just reason because the fiat alone is suffering from inlation and you do not want to start touching what should be of help agaisnt an already diminishing fiat that is already an issue you are dealing with.
you can decide to spend your bitcoin and there is nothing that is wrong about it but if you are considering using your bitcoin as an edge agaisnt inflation, then it is better you spend your fiat and let your bitcoin holding be so you it rather place you at a better position knowing that the price of bitcoin is even a reward to any holder that is not touching his holding. if you even have proper provision for an emergency fund which is going to be a fiat you have kept aside for those kind of expenses, then there will not be a need to spend your bitcoin that should serve as an edge against inflation.
I agree that holding Bitcoin and limiting the usage of fiat would be wise in case the ultimate objective is to avert being affected by inflation. That way, your Bitcoin continues to appreciate and your fiat continues to become poorly bought.
Personally, I attempt at separations. I keep the majority of Bitcoins in form of savings, whether it is a payment or just a taste. In that way, I can continue to use it as money, but not to spend any of my long-term stack.
Naturally, it is also desirable to have an emergency fiat fund, as otherwise people may run and sell their Bitcoin when money is needed. To me, Bitcoin is a hedge and a currency to use, it is just a matter of how much you allocate to it on each side.
