- Vitalik Buterin’s rejected U.S. work visa in 2013 forced his return to Canada, leading to Ethereum’s creation.
- Had Buterin stayed at Coinbase, Ethereum might have developed differently as part of their platform infrastructure.
A post from Coinbase CEO Brian Armstrong on X today sheds light on an unexpected origin story for Ethereum. The message details how immigration challenges in the United States shaped the platform’s birth. As Ethereum marks its 10th anniversary on July 30, 2025, the account offers a clear look at a key moment in crypto history.
Ethereum.
Fun fact: I met @VitalikButerin in 2013 at the San Jose Bitcoin conference when he was writing for Bitcoin Magazine (his writing was great).
A few months later I invited him to come by Coinbase's first office in San Francisco for a visit and he showed us some cool… https://t.co/VPkq6BcX1j

Armstrong recounts meeting Vitalik Buterin in 2013 at a Bitcoin conference in San Jose. Buterin worked as a writer for Bitcoin Magazine at the time. A few months later, Armstrong invited him to Coinbase’s first office in San Francisco.
Alongside co-founders Fred Ehrsam and Olaf Carlson-Wee, the team offered Buterin a job. However, a U.S. work visa did not come through, forcing Buterin to return to Canada. That return sparked the creation of Ethereum.
Armstrong notes the rigid immigration process contributed to this shift and closes with a birthday wish for the platform, launched on July 30, 2015. The post quotes an earlier message from @0x_ba praising Bitcoin, but Armstrong shifts focus to Ethereum here.
Responses followed quickly. David Hoffman, known as @TrustlessState, replied suggesting Coinbase nearly blocked Ethereum’s development. Laura Shin responded with a simple “Ethereum.” Meanwhile, @ClintonEdwards posted, referencing a 2023 thread by @GhostofWhitman that labels Ethereum a “scam.” That thread raises concerns about its structure, though today’s discussion centers on Armstrong’s narrative.
Buterin’s work began in late 2013
He collaborated on a project called Mastercoin and recognized blockchain’s potential beyond payments. In November, he drafted a white paper for Ethereum, drawing interest from others. By January 2014, he presented the idea at a Bitcoin conference in Miami with Mihai Alisie, Anthony Di Iorio, and Charles Hoskinson. A crowdfunding campaign ran from July 20 to September 2, 2014, producing 60 million Ether for sale, the initial tokens for the platform.
The immigration factor adds context
Buterin’s visa denial redirected his efforts. A 2024 report from the Center for Strategic and International Studies indicates immigrants drive significant tech growth in the U.S., with visa holders contributing heavily from 1990 to 2010. Had the process allowed Buterin to stay, he might have joined Coinbase. That outcome could have linked Ethereum to their platform, especially given Coinbase’s later support for Ethereum and its tokens in 2018.
Now, a decade after its start, Ethereum serves as a platform for decentralized finance and digital collectibles. Questions about its design linger, as seen in the @GhostofWhitman thread. Armstrong’s post highlights how chance influences major developments. What might have happened if Buterin had stayed in the U.S. remains an open question as Ethereum reaches this point.
