I dont use crypto currency as a payment in my daily life because in my country, there arent shops accepting crypto currencies yet. I have ordered a crypto debit card from Tenx and waiting for it to arrive, I cant wait to try using.
But on the other hand, I do not have many BTC that I can keep spending so I would rather spend fiat and keep my BTC.
Excactly and even the transaction fees wouldn't make it possible to spend your bitcoins on the daily basis on little items like coffee or groceries that is why it is best to invest in it until all the possible issues associated with it are solved.
