Coinbase CEO Brian Armstrong Says Bitcoin Keeps USD in Check

Brian Armstrong, CEO of the largest exchange in the U.S. Coinbase, says Bitcoin could help maintain fiscal discipline in the United States and indirectly support the U.S. dollar’s role as the global reserve currency. 

In a recent interview on Tetragrammation with Rick Rubin, Armstrong stated that Bitcoin (BTC) creates a form of healthy competition for the dollar and prevents reckless fiscal policy. 

Sharing the clip on X, Armstrong said, “It creates competition in a way that’s healthy for the dollar, which helps to provide a check and balance against high inflation and deficit spending.” He argued that when inflation or deficit spending becomes excessive, people may seek alternatives like BTC. 

He added, “if there’s too much deficit spending or inflation in the US, people will flee to Bitcoin, you know, times of uncertainty.” 

U.S. debt surge and dollar pressure

The U.S. government’s national debt has risen dramatically in recent years. According to the U.S. Congress Joint Economic Committee, the national debt is now approaching $38.5 trillion, increasing by roughly $69,433 per second for the past year. 

Armstrong’s comments come amid growing concern that high debt and inflation could erode confidence in the dollar if not managed carefully.

Bitcoin’s price, which peaked above $126,000 in October 2025, its all-time high, before pulling back, has been seen by some analysts as a “debasement trade”—a hedge against currency weakening, alongside gold’s rally. 

Armstrong said, “Bitcoin is special and unique in the sense that it is like digital gold. It has the highest trust, I would say, because it’s the original incarnation of crypto.”

The CEO believes Bitcoin’s existence can help remind markets and policymakers of monetary risks. “I actually think in a strange way, you know, Bitcoin is helping extend the American experiment in the sense that it creates competition with the dollar,” he said.

The role of stablecoins and the USD

Meanwhile, other leaders in the industry believe that stablecoins, which are digital currencies tied to the U.S. dollar, can be more directly connected to maintaining dollar supremacy in the world.

Unlike Bitcoin, stablecoins are designed to hold a steady value and are increasingly being adopted for everyday payments, remittances, and business transactions.

In July 2025, the U.S. passed the GENIUS Act, a comprehensive framework to regulate payment stablecoins and require them to hold safe assets like the U.S. Treasuries to back their tokens.

This move helped increase the confidence of financial institutions and contributed to the rapid growth of the stablecoins. Its market capitalization surpassed $312 billion and forecasts suggest that it may grow to over $2 trillion by 2028.

U.S. Treasury officials have suggested that dollar‑backed stablecoins could help cement global demand for the dollar by making it easier for people and businesses worldwide to use digital dollars in everyday commerce.

Indication of a changing financial environment

The debate highlights two contrasting views within the crypto world, Bitcoin as a store of value and check on monetary policy versus stablecoins as a practical digital dollar extension. 

Both trends indicate a changing financial environment in which digital assets are becoming more influential in the traditional money markets and finance on the global scene.

The debate on whether Bitcoin will eventually moderate fiscal policy or stablecoins will cement the use of the U.S. dollar in the world economy, but the discussion shows how digital money is transforming economic thought, even among policymakers and institutional leaders.
