I try to live a bitcoin standard.
I learned what I usually have to spend each month. I keep only that amount of btc in an exchange that offers a bitcoin backed credit card. I look up stores and services that accept bitcoin and use this services and stores mainly. Bitrefill and TheBitcoinApp are used excessively. I pay insurances and taxes in fiat as I have to.
So: Yes, yes, yes, yes, yes.
Key for me was just good knowledge about my reoccurring payments and spending habits.
