Thanks, that's very cool. I actually mentioned Steemgiftcards in the article briefly. The problem is you can't reload the gift cards yet, so you have to pay a new card fee every time. At least with Shift, I only had to pay that fee once.

Edit: Maybe just paying the fee each time would still be cheaper than having to pay Bitcoin fees each time. Still, you have to wait for your card to be delivered, so the option isn't as convenient as having a card you can reload each time.
