Glauber Contessoto bought into Dogecoin at just the right time. Inspired by tech billionaire Elon Musk’s endorsement of the dog-themed memecoin, the 37-year old spent his life savings and maxed out credit cards to buy $250,000 worth in February 2021. His family and friends worried he was making a big mistake but, just two months later, he became a millionaire.

As Dogecoin took off in mid-2021, Contessoto’s holdings ballooned to $3 million, and he parlayed his good fortune into a sizable internet following under the handle “SlumDOGE millionaire.”

The good times didn’t last, however, as Dogecoin plummeted from $0.53 to $0.06, leading Conessoto to lose both his millions and his celebrity status. But he didn’t sell. He remained convinced that Dogecoin, and his social media accounts, would make their way back into the spotlight—and he was right.

Amid the current crypto boom, Dogecoin is soaring again and Contessoto’s fortune has grown back to more than $2 million. While he plans to sell a portion of it this time, he is still confident in the future of Dogecoin.

“Dogecoin, to me, it was always a conviction play… Once I dove into cryptocurrency, bitcoin, blockchain technology, and ultimately Doge, I was like, wow, this is a technology that's not only here to stay, it's going to thrive in the future,” Contessoto told Fortune.

When Fortune sought to verify the size of Contessoto’s investments, he declined to share his wallet address, saying that he doesn't want people to know exactly how much Dogecoin he has but that it is over 5 million. He also provided this screenshot.

After three lackluster years, Dogecoin has grown over 200% in the last month boosted by President-elect Donald Trump’s pro-crypto platform and Musk’s appointment to head the newly created Department of Government Efficiency, or D.O.G.E.—a nod to the billionaire’s favorite crypto.

Becoming the SlumDOGE Millionaire 

When Contessoto splurged on Dogecoin, he was looking for ways to change his life. Upon googling “How to become a millionaire?” he found that most successful people have multiple streams of income and decided to start investing.

Intrigued by the explosive price action of crypto and Musk’s fascination with Dogecoin, Contessoto risked it all on the Shiba Inu–themed memecoin.

“Not only is this Dogecoin thing catchy, trendy, and I can see it gaining traction with millennials…but now we also have the richest man in the world that's also a big fan of it,” he said.

Contessoto saw something in Dogecoin that was missing from most other cryptocurrencies: a familiar face. Popularized in 2013, the doge meme—a sassy orange Shiba Inu giving the side eye—is among the most ubiquitous internet memes, recognizable to almost any Gen Zer or millennial.
