Multicoin Capital co-founder Kyle Samani has shared a candid reflection on his early journey in crypto — and the moment he decided to walk away from Ethereum despite its historic success.

In a post on X, Samani said Ethereum was his entry point into the cryptocurrency industry and his first major source of wealth, describing it as both a mentor and a foundation for his career.

“Ethereum got me into crypto and was my initial source of wealth,” Samani wrote.

Ethereum’s Historic Rise — and a Breaking Point

Samani highlighted Ethereum’s rapid ascent, noting that ETH became the fastest asset in history to reach a $100 billion market capitalization. However, he said that same period exposed structural issues that ultimately pushed him away from the ecosystem.

The turning point came at Devcon 3 in Cancun, Mexico, in November 2017.

At the time:

Ethereum gas fees were surging

Network congestion was worsening

Scaling solutions were still largely theoretical

According to Samani, this created an “unprecedented sense of urgency” around scalability — one he felt Ethereum was not addressing fast enough.

“Gas fees were soaring, and there was clearly a need to scale as quickly as possible,” he said.

From Ethereum to Alternative Layer-1s

Samani’s departure from Ethereum in 2017 would later shape Multicoin Capital’s investment thesis, including its early and vocal support for high-performance Layer-1 blockchains such as Solana. Today, Samani also serves as chairman of SOL Treasury Forward, further underscoring his long-term conviction in alternative scaling approaches.

A Broader Industry Debate

Samani’s comments reignite a long-running debate within crypto:

Ethereum’s security and decentralization vs. performance and cost

The pace of scaling through Layer-2 solutions versus new base-layer designs

While Ethereum remains the dominant smart-contract platform by market share, his remarks reflect why many early crypto investors and builders explored other ecosystems during periods of network stress.
