role	software engineer, Dogecoin cocreator
known for	Dogecoin, posting as Shibetoshi Nakamoto, selling everything in 2015

Billy Markus is the American software engineer who cocreated Dogecoin in 2013, sold out for the price of a used car in 2015, and returned as the beloved CT commentator Shibetoshi Nakamoto.

Billy Markus is an American software engineer from Portland, Oregon, who worked at IBM before crypto. In December 2013 he cocreated Dogecoin with Jackson Palmer, assembling the coin in a matter of hours as a joke that fused the doge meme of Kabosu with the era's altcoin boom, and in doing so accidentally authored the founding document of meme coin history.

Creating and leaving Dogecoin

Markus wrote the code side of Dogecoin while Palmer supplied the meme and the domain, and the coin found an instant tipping community on Reddit. Markus left the project in 2015 amid burnout and community drama, and famously sold his entire DOGE stack for roughly 10,000 dollars, a sum he compared to the price of a used Honda Civic; he later clarified that he used the money for rent after a layoff and never actually bought the car. The detail, which he has repeated often, became a canonical trench parable about selling early, and it is sometimes misattributed to his cocreator Jackson Palmer, to whom it does not belong. He therefore captured almost none of the tens of billions of dollars of value Dogecoin later reached.

Shibetoshi Nakamoto

During the 2021 mania Markus reemerged on Twitter as Shibetoshi Nakamoto, a name riffing on Bitcoin's pseudonymous founder, and became one of the most followed original voices in crypto commentary. Profiles by DailyCoin and 99Bitcoins describe his register: sarcastic, self deprecating, openly skeptical of the market that made his joke worth billions. He has repeatedly said he holds relatively little DOGE, that most crypto trading is gambling, and that people who ape into random coins should expect to lose money. He sold NFTs of his original artwork in 2021, engages in regular public banter with Elon Musk about Dogecoin, and comments on every major market crash, which outlets like U.Today cover as if delivering statements from a head of state. By August 2026 his account had grown to about 4.6 million followers. His register remains consistent: "thank god for meme coins. imagine how boring crypto would be if it was just bitcoin," posted August 17, 2026, drew about 1,900 likes.

Position in the culture

Markus occupies a unique seat in the trenches: the founder who kept the humor and skipped the bag. He mocks both the maximalists and the doomers, defends Dogecoin as harmless fun while calling most successor coins cash grabs, and his 2015 exit price is cited constantly as the ultimate cautionary tale about conviction. Unlike his cofounder Jackson Palmer, he remained inside the culture, and his account is treated as one of the last honest broadcasts from the origin of the meme coin era.

In August 2026, in an exchange about modern trench tokens, he offered the origin author's own grading of the culture he started: "early doge had a community that wanted to get to know each other and do fun things together as a community, and in general a healthy community needs something beyond looking at charts and some kind of personality and longevity more than stunts," and "good communities build things and have fun and bad communities demand people do things for them."
