Nakagawa isn't the first person to find a way to turn Dogecoin into cheese-topped sustenance. Last month, a redditor showed off a Dominos pizza he had "bought" with 5,000 Dogecoin, but explained in the comments that he had convinced the delivery person to pay for the pizza out of his own wallet in exchange for the cryptocurrency. The JJ Dolan's story is closer to directly purchasing through a vendor, but doesn't represent a scalable way for a retail outlet to deal in Dogecoin.
However, these sorts of third-party transactions still may signify a trend toward more general acceptance of the cryptocurrency. And pizza is a traditional starting point: The first real-world bitcoin transaction in 2010 is widely reported to have been when a Florida programmer sent an individual in the U.K. 10,000 bitcoins to spend about $25 ordering the programmer Papa John's online.
