Indeed, earning bitcoin or some other crypto in credit card rewards is a new and emergent fin tech thing that crypto companies are offering their customers. I'm a customer of BlockFI and i have their BLOCKFI Visa that pays out bitcoin rewards monthly, so they do have a FMV (or basis) at time of reward. I'm inclined to just pay the "interest" taxes and adjust my cost basis down the road when I redeem the coins.
Given crypto is becoming more and more mainstream, i would suggest to TurboTax developers to account for these transactions in their software so that one can adjust for these things in the income entry. That said, so do the financial institutions that are preparing the 1099's.
Thanks very much for the reply and Happy New Year!
