I prefer FIAT for F2F Tx. Bitcoin is online money and an investment asset for me. I prefer to spend my FIAT and HODL Bitcoin
The process is to spend the bitcoin then immediately replenish it into your holdings.
This way you support the economy / currency and improve your own chances of your holdings being worth more one day.
Terrible idea to just hold and only spend fiat IMO.

Agree, in general I'm trying to hold my btc for the change that there's a future value increase. However, actually spending them on the street means that businesses that adopt them, set up to use them are validated in that decision which in turn increases the value of my holdings.
Second of all, it's was just plain fun to go out and do it. I'm planning on doing it again, tbh.
