Bitcoin as Digital Gold, Stablecoins Take Over Payments, Says Coinbase CEO Armstrong

Coinbase CEO Brian Armstrong says Bitcoin has found its real job: not everyday payments, but “digital gold.” Stablecoins, he argues, are now doing the transactional heavy lifting.

Bitcoin as scarce savings, not checkout money
Stablecoins are becoming the practical crypto payment rail
U.S. regulation is giving stablecoins a clearer runway

Armstrong made the comments on the People by WTF podcast with Zerodha co-founder Nikhil Kamath. The view is blunt, but not exactly surprising: Bitcoin has settled into a decentralized, scarce asset that is better at preserving value than buying coffee.

That is a big turn from the original “peer-to-peer electronic cash” idea. Bitcoin can still move value, but as an everyday payment tool, it keeps running into the same problem: volatility. If the thing you spend can swing hard between breakfast and lunch, it is a lousy unit for routine payments.

Bitcoin is trading around $64, 523, roughly 49.1% below its all-time high of $126, 080, according to Coingecko. That kind of swing is exactly why many holders treat BTC like a savings asset, not spending money. Nobody wants to find out they bought dinner with next year’s beach house deposit.

Armstrong said Bitcoin’s fixed supply is part of why it naturally gravitates toward a store-of-value role. Scarcity is what makes Bitcoin attractive in the first place. Scarcity is also why people get very stingy about spending it.

He also pointed to the Lightning Network, the Bitcoin payment layer built to make transactions faster and cheaper. In Armstrong’s view, it has not seen wide adoption, leaving stablecoins to fill the payments gap instead.

That is the uncomfortable truth for the “Bitcoin will replace Visa” crowd: markets care less about ideology than usability. Stablecoins are stable. Bitcoin is not. For payments, that difference matters more than the loudest thread on X wants to admit.

According to data from DefiLlama, the stablecoin market is approaching $310 billion in total value. Tether’s USDT sits at about $184 billion, while Circle’s USDC is around $73 billion. That is not fringe infrastructure anymore. That is serious payments plumbing with real liquidity behind it.

Armstrong said fiat-backed stablecoins now handle the payment role Bitcoin was originally expected to play. That matches the practical reality. Stablecoins combine blockchain speed with a steady value, which makes them useful for transfers, settlement, trading, and payments without the drama of a token that moves like it had three energy drinks and bad news.

Much of that activity now happens on networks such as Base and Solana, Armstrong said. Both are built for fast, low-cost transfers, which makes them better suited to transactional use than a base-layer asset designed first and foremost to be scarce and hard to inflate away.

The regulatory picture matters too. Armstrong cited the GENIUS Act, signed into law in July 2025, as a key reason stablecoins are gaining traction in the United States. The law created a clearer federal framework for stablecoins, including reserve and disclosure rules that make the sector easier to plug into mainstream finance.

That kind of clarity cuts both ways. It can bring legitimacy, institutional adoption, and better consumer protections. It can also make stablecoins more dependent on compliant issuers, reserve management, and government oversight. Crypto gets adoption one regulator at a time, apparently, whether the cypherpunks like it or not.

Armstrong’s point is not that Bitcoin failed. It is that Bitcoin found the role the market values most. In his framing, BTC is a decentralized, scarce digital asset comparable to gold, a place to store value, not a tool for buying lunch.

There is a fair counterpoint here. Bitcoin maximalists would argue that BTC never needed to win the retail payments race to matter. Bitcoin can still serve as a censorship-resistant settlement asset, a savings vehicle, and a monetary base. Lightning and other second-layer tools may still matter over time, even if they have not delivered mass-market payments dominance yet.

In other words, Bitcoin being treated like digital gold is not automatically a downgrade. It may simply be the market saying: this is the hardest money in the room, and stablecoins can handle the plumbing.

That division of labor is probably more realistic than the old “one crypto to rule them all” fantasy. Bitcoin is increasingly the asset people hold. Stablecoins are the instruments people move. Different jobs, different tools.

What does “digital gold” mean?
It means Bitcoin is being treated more like a scarce store of value than a day-to-day spending currency. Gold is something people save, not something they swipe at the checkout line.

Why is Bitcoin not widely used for payments?
Armstrong’s answer is that fixed supply encourages holding and volatility makes spending awkward. Even with Lightning, Bitcoin still has friction that stablecoins mostly avoid.

Why are stablecoins better for payments?
They are tied to fiat currencies like the U.S. dollar, so their value stays relatively stable while still moving on blockchain rails. That makes them practical for transfers, settlement, and everyday transactions.

How big is the stablecoin market?
DefiLlama data puts it near $310 billion, with USDT and USDC dominating. That scale suggests stablecoins are now core crypto infrastructure, not a sideshow.

Did the GENIUS Act matter?
Yes. Armstrong says it improved the U.S. regulatory backdrop for stablecoins, and the law’s clearer framework should make adoption easier for issuers and users alike.

Does Bitcoin still matter if it is not the main payments network?
Absolutely. Under Armstrong’s view, Bitcoin’s strongest role is as a decentralized, scarce monetary asset. That may be less flashy than “global payments, ” but it is also more consistent with how the market already uses BTC.

Bitcoin’s path from cash experiment to digital reserve asset is not a failure story. It is a market reality story. Stablecoins are doing the transactional work, Bitcoin is doing the monetary work, and the rest is tribal noise.
