When Bitcoin first appeared out of digital thin air, it was hailed as having the potential to upend the way people spent money. But more than a decade later, cryptocurrency is still only trickling into the mainstream.

This week, Tesla bought $1.5 billion worth of Bitcoin and said it plans to start accepting it as a form of payment for its electric vehicles. The price of Bitcoin immediately spiked as the move seemed to signal a shift toward broader acceptance of cryptocurrency in general. But is this just another fleeting Elon Musk stunt, or will it actually be a sustainable way of doing business?

This week on Gadget Lab, WIRED staff writer Greg Barber joins us to talk about Tesla's crypto plans, the reemergence of Dogecoin, and why the blockchain hasn't exactly revolutionized currency yet.
