Bitwise CIO Matt Hougan predicts Bitcoin’s market cap could reach $30 trillion within ten years, drawing a parallel to gold’s expansion after its ETF launch in 2004. He noted gold’s market was about $2.5 trillion then, while Bitcoin was around $2 trillion when spot ETFs launched in 2024. Hougan sees substantial long-term upside, with the main risk being whether investors can hold through multiple bull and bear cycles.
