I dont hold any FIAT either Mopar. Bitcoin trumps them all. But as a medium
of payment ATM its not as easy to pay for "everything".
I use coincards.com to buy gift cards with Bitcoin to use at places that dont accept Bitcoin, and I use thebitcoincompany app to buy prepaid visa cards as well.
if all else fails, I use my gemini card to pay with fiat then use Bitcoin to pay the bill.
