Brian Armstrong went on Peter Diamandis' podcast and made his position plain: he is long Bitcoin, he is staying long, and he expects the price to be substantially higher by the end of the decade.

"I'm as bullish as ever on Bitcoin, and still long — as always," Armstrong said on the podcast. "I think by 2030 we're gonna have a much higher price."

Armstrong's argument rests on Bitcoin's fixed supply of 21 million coins against expanding global demand. He has pointed to two specific catalysts: clearer U.S. crypto regulation and growing institutional adoption through spot Bitcoin exchange-traded funds, approved in January 2024. The supply cap is the foundation—every demand catalyst compounds against an asset that cannot issue more of itself.

His latest comments follow a more explicit forecast he posted on X in 2025: "I think we'll see $1M per bitcoin by 2030." Armstrong acknowledged that Bitcoin's four-year boom-and-bust cycles look alarming in the moment but argued they are less dramatic over longer time frames. "It's never as good or as bad as it seems," he said. "The classic four-year cycle feels extreme, but in reality, they're not that extreme."

Armstrong's forecast echoes calls from other industry executives. Block CEO Jack Dorsey said Bitcoin will reach at least $1 million by 2030 and argued that growing global adoption could eventually push Bitcoin's market capitalization above $20 trillion. "I do think it hits that number and goes beyond," Dorsey said.

ARK Invest CEO Cathie Wood has set a range rather than a single number. Her firm's base-case scenario puts Bitcoin between roughly $710,000 and $1.5 million by 2030. Wood has described Bitcoin as "digital gold" and cited rising institutional ownership as the primary driver in her model.

MicroStrategy Executive Chairman Michael Saylor has built the company's entire corporate treasury around Bitcoin, making his long-term bullish view a matter of corporate record.

Armstrong's credibility on this topic is structural, not rhetorical. Coinbase is the largest U.S. crypto exchange and reports publicly as a Nasdaq-listed company under the ticker COIN. Armstrong holds Bitcoin personally and runs a business whose revenue scales directly with Bitcoin trading volume and price. His incentive to be bullish is real, and so is his exposure to being wrong.

Bitcoin trades at $72,459, up 5.7 percent in the past 24 hours as of Aug. 20. Ethereum is up 11.7 percent in 24 hours to $2,328. The broader equity market is lower—the S&P 500 is off 0.4 percent, the Nasdaq down 0.9 percent.
