Bitcoin vs. Gold: Can Fixed Supply Assets Become Money?

A renewed academic dispute over whether Bitcoin can function as everyday money has exposed a fundamental divide in monetary theory: whether an asset’s volatility disqualifies it from becoming a medium of exchange, or whether that volatility is merely a temporary symptom of an asset still being priced by the market.

Saifedean Ammous, author of the 2018 book “The Bitcoin Standard,” argued Tuesday on X that Bitcoin already operates as money. His position rests on the premise that holding the asset constitutes using it, rendering the current lack of retail payment adoption irrelevant to its broader monetization trajectory. Ammous contends that as Bitcoin’s market capitalization expands, its price swings will eventually fall below those of gold.

That assertion directly challenges Lawrence H. White, a monetary economist and professor whose recent book, “Better Money: Gold, Fiat, or Bitcoin?,” examines competing monetary systems. White pointed to Bitcoin’s algorithmically fixed supply of 21 million coins as a structural flaw for transactional use. Because new units cannot be minted to absorb sudden spikes in demand, White argues, the price must absorb the entire shock. He credited this mechanical rigidity for the dominance of stablecoins in crypto transaction volume, noting that dollar-pegged tokens have effectively captured the payments market Bitcoin was originally designed to serve.

White’s critique touches on a core principle of traditional monetary economics. Under a gold standard or fiat regime, supply elasticity helps stabilize purchasing power. When demand for money rises, central banks or mining outputs can theoretically expand the supply to prevent severe deflationary pressure. Bitcoin intentionally eliminates this mechanism. Its halving cycle, which cuts new issuance roughly every four years, ensures a disinflationary path regardless of economic conditions. For proponents like Ammous, this predictability is the asset’s primary value proposition. For critics like White, it is a fatal barrier to functioning as a unit of account for daily commerce.

The debate arrives as institutional forecasts increasingly measure Bitcoin against gold rather than fiat currencies. In May 2025, André Dragosch, head of European research at Bitwise, projected Bitcoin could reach $1 million by 2029. At that valuation, the cryptocurrency would approach gold’s current market capitalization of approximately $29 trillion. Today, Bitcoin sits near $1.6 trillion, meaning it requires roughly an 18-fold increase to match the precious metal’s global footprint.

Gold itself carries significant price volatility despite its ancient status as a monetary anchor. The metal’s price fluctuates regularly based on interest rate expectations, geopolitical risk, and central bank accumulation. Bitcoin’s historical volatility has consistently exceeded gold’s, but its rolling 30-day and annualized volatility metrics have steadily declined over successive market cycles as liquidity deepens and institutional participation grows.

Blockstream CEO Adam Back echoed the shifting narrative in April 2025, predicting Bitcoin would begin rivaling gold specifically as a monetary hedge driven by rising fiat inflation and global financial instability. Back’s framing aligns with a growing segment of the industry that views Bitcoin not as a replacement for Visa or cash, but as a digital alternative to sovereign debt and physical bullion.

The divergence between these perspectives reflects how different factions evaluate the same underlying technology. Stablecoin networks processed trillions of dollars in settlement volume throughout 2024 and 2025, cementing their role in cross-border payments and decentralized finance. Meanwhile, Bitcoin’s base layer continues to process fewer transactions per day than major credit card networks, though its total settled value remains vastly higher per transaction, reinforcing its use as a high-value settlement asset rather than a point-of-sale currency.

Separately, hardware security firm Ledger recently began testing implantable devices configured to interact with Bitcoin ETFs, exploring custodial alternatives to traditional hardware wallets as institutional access models evolve.
