I have a Shift card. It's not a credit card though - it's a Visa-branded debit card. I don't really use it though. Here in USA, we need to track all use of crypto to buy things as a taxable capital gains event. Which makes using the card a headache.

Hmm... just pulled the Shift card out of the desk drawer. Looks like I don't have a Shift account any longer. Expired 1/19. They didn't contact me to re-up. Maybe because my relative non-use is nothing but a headache for them?
