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.
Myself and my Bitcoin buddy use Bitrefill.com to do the same, we can buy our weekly
groceries with their gift cards, very very very low fees!
Still need cash to be able to pay for other items like fuel otherwise asking to
pay with Bitcoin would be the same as asking to pay with Gold/silver bullion!
