Why can’t you do both? If you are going to make a fiat purchase use bitcoin instead and buy more bitcoin with the fiat you would have spent.
So if the merchant won’t accept bitcoin:
1) take the fiat you would have spent and exchange it for bitcoin
2) pay the merchant with a fiat credit card
3) when the credit card payment is due 30+ days later, exchange enough, bitcoin to cover the fiat payment
Most of the time you will have bitcoin left over from doing this transaction that you can HODL keep stacking. But even if you don’t, you have lived on a bitcoin standard as a first principle
It seems like a lot of double handling of the money and going through exchanges you might be hit with KYC. If you could buy a prepaid debit card in bitcoin, or have a credit card that accepts bitcoin, this would work much smoother.
It is a lot of double handling but I find it worth to live on a bitcoin standard. My exchange where I do most of this will be issuing a credit card soon that will pay off with bitcoin automatically. In the meantime, I do the extra work based on first principles.
Personally I’m leveraging my software development team to build more tools that will support bitcoin as a unit of account that will work with the financial solutions that will be forthcoming
My problem here in Japan is the KYC on the exchanges. I bought the majority of my bitcoin before these policies were implemented and i don't want to dox myself.
What is the name of your exchange and do they have KYC policies? I would love to get a bitcoin credit card.
