Mostly to be paid and for ordering digital things online. I will use fiat for local things and online I use crypto unless I am forced to use bank transfer or paypal or other.
Bitcoin is easier and cheaper for me.
In 2017 bitcoin was banned by our goverment to become a currency in my country.
Now, Bitcoin is legal as a commodity here. However, it still can’t be used as a currency.
We called it digital asset or crypto asset instead of cryptocurrency.
Personally I have never spend my bitcoin for something, online or offline.
But, sometime I got paid with bitcoin for services that I provided (cross border payment).
I exchange some of my bitcoin into fiat, I also trade and hodl it.
Currently, I want to invest my profit into stocks.
I am not a bitcoin-die-hard who hodl bitcoin and doing nothing about it.
(Maybe I am bad about it)
You can still use it. Noone will know. You have the right to accept whatever you want as payment.
