Coinbase CEO Warns: U.S. Debt Crisis Could Pave Way for Bitcoin as Reserve Currency
Brian Armstrong, CEO of Coinbase, delivered a sobering message this week: if the U.S. fails to rein in its ballooning national debt, Bitcoin could replace the U.S. dollar as the world’s reserve currency.
“If the electorate doesn’t hold Congress accountable to reducing the deficit and start paying down the debt, Bitcoin is going to take over as reserve currency,” Armstrong wrote on X. “I love Bitcoin, but a strong America is also super important for the world. We need to get our finances under control.”
His remarks came in response to a chart from World of Statistics, showing the U.S. national debt skyrocketing from $5.7 trillion in 2000 to $36.9 trillion in 2025—a more than sixfold increase in 25 years.
A Debate Sparked Across Crypto and Culture
Armstrong’s comments ignited widespread debate online, drawing reactions from major figures in both the crypto space and mainstream media.
YouTube creator MrBeast asked bluntly,
“We’re just going to casually build up over $100 trillion in debt in our lifetimes, and people will just continue to be chill with it and loan us money?”
Crypto influencer Wendy O pushed back on Armstrong’s prediction:
“Bitcoin will never be a reserve currency because of its volatility. But it will be desired. A stablecoin… yes.”
HODL15Capital echoed Armstrong’s concern from a monetary angle, saying:
“Bitcoin has no top because fiat printing will never end.”
Elon Musk also weighed in, retweeting Armstrong’s post with just an American flag emoji, signaling his support.
Musk Criticizes GOP Spending Amid Broader Fiscal Concerns
Musk later expanded on the issue, criticizing Congressional Republicans for backing a controversial spending bill dubbed the “One Big Beautiful Bill.” He called it
“a disgusting abomination” and added, “Interest payments already consume 25% of all government revenue. If the massive deficit spending continues, there will only be money for interest payments and nothing else.”
In another post, he called for electoral accountability:
“In November next year, we fire all politicians who betrayed the American people.”
His remarks accompanied a quote-tweet from Matt Van Swol, highlighting excessive GOP spending and prioritization of perks over fiscal reform. All but five Republican congressmen reportedly voted yes on the bill, while all 214 Democrats voted no.
The U.S. Debt Crisis and Bitcoin’s Rising Role
The backdrop to this growing concern is a looming U.S. fiscal crisis. According to Congressional Budget Office projections, interest payments on the national debt could reach $1 trillion this year and may double by the mid-2030s.
Several factors are driving this trajectory: rising entitlement spending, pandemic-era fiscal programs, and bipartisan reluctance to raise taxes or trim popular expenditures.
Historically, the dollar’s dominance has rested on the size and stability of the U.S. economy and its Treasury markets. Replacing it with Bitcoin would require dramatic overhauls in monetary policy, regulation, and sovereign finance.
Yet, institutional interest in Bitcoin is rising. With BTC trading above $100,000 in 2025 and spot ETFs now mainstream, Bitcoin’s narrative as “digital gold” is no longer fringe. While volatility remains a key obstacle, it has gradually declined, strengthening Bitcoin’s appeal as a long-term store of value.
A Tipping Point?
Armstrong’s warning highlights growing concern over America’s fiscal sustainability and the potential global consequences of unchecked debt. While the idea of hyperbitcoinization—Bitcoin replacing fiat currencies at scale—remains speculative, it is no longer dismissed as impossible.
In the eyes of Armstrong, Musk, and a growing chorus of voices, the world is inching closer to a financial crossroads. Whether policymakers act in time may determine whether the dollar retains its reserve currency status—or cedes that ground to decentralized alternatives.
