Saifedean Ammous, author of the influential 2018 work The Bitcoin Standard, has entered a growing debate over whether Bitcoin can function as genuine money, arguing that volatility concerns are overblown and that the cryptocurrency’s reduced price swings will eventually enable broader use as a medium of exchange.
According to reporting by Cointelegraph, Ammous made his case in a Tuesday post on X, directly challenging economist Lawrence H. White’s assertion that Bitcoin’s fixed supply creates too much price instability for reliable payment use. The disagreement touches on a fundamental question: whether Bitcoin’s monetary role depends on price stability or broader adoption dynamics.
The Fixed Supply Debate
White, author of Better Money: Gold, Fiat, or Bitcoin?, grounded his position in economic first principles. A currency with no ability to adjust supply in response to demand shocks will experience wild price swings, he argued—making it impractical for everyday transactions. This constraint, White suggested, explains why stablecoins have captured vastly more transaction volume than Bitcoin itself.
Ammous countered that this logic misses the distinction between money and payment rails. “Holding Bitcoin is using Bitcoin as money, and its lack of widespread use as a method of payment is no evidence against its monetization unfolding,” he wrote, implying that Bitcoin’s current role as a store of value represents a valid monetary function even without transaction volume dominance.
The debate echoes a core tension in monetary economics: whether a medium of exchange must be actively circulated to retain monetary status, or whether accumulation itself constitutes legitimate money-holding behavior.
When Bitcoin Meets Gold’s Scale
Both economists acknowledge a shared benchmark: Bitcoin potentially matching gold’s market valuation. That threshold remains distant. Gold’s market capitalization sits near $29 trillion, while Bitcoin’s $1.6 trillion valuation would need to expand roughly 18-fold to achieve parity.
Yet industry forecasters see a credible path. Bitwise’s European research head André Dragosch told Cointelegraph in May 2025 that the firm’s internal models predict a $1 million Bitcoin price by 2029—a level that would place Bitcoin alongside gold in global monetary relevance. Blockstream CEO Adam Back offered a similar thesis in April 2025, arguing that mounting fiat inflation and financial instability would drive Bitcoin adoption as a monetary hedge, much as investors have traditionally used precious metals.
Volatility as a Transition State
Ammous’s core claim rests on an implicit assumption: as Bitcoin accumulates more users and deeper market liquidity, its price volatility will compress toward levels more compatible with payment use. At that point, the fixed-supply constraint White identifies becomes irrelevant—the network would function less like an experimental asset and more like established reserve currencies.
This hinges on empirical outcomes beyond either economist’s control. If Bitcoin’s price volatility continues declining as institutional adoption deepens, Ammous gains credibility. If volatility persists alongside mainstream acceptance, White’s payment-efficiency concerns retain force.
The resolution matters less for Bitcoin price prediction than for understanding what role the asset actually plays in the financial system—and whether that role can genuinely expand beyond wealth storage into routine transactional currency, with or without price stability.
