Saifedean Ammous Says Bitcoin Already Functions as a Medium of Exchange

Ammous Says Bitcoin’s Monetary Role Extends Beyond Payments

Ammous was responding to economist Lawrence H. White’s argument that Bitcoin’s fixed supply contributes to price volatility, limiting its usefulness for routine exchange. Ammous disputes that interpretation, arguing that demand-driven monetization can enlarge Bitcoin’s market sufficiently for volatility to decline over time. The disagreement centers on whether fixed supply is fundamentally incompatible with monetary stability or whether a larger, deeper market can absorb demand shocks more effectively. That debate echoes the wider comparison between Bitcoin and gold, where volatility remains a central distinction between the two assets despite their shared scarcity narratives.

Ammous also rejects the assumption that money must first be widely used for retail payments before it can become monetized. In his framework, people choosing to hold Bitcoin as savings are already using it for a monetary purpose, while payment adoption can develop later as volatility falls and liquidity deepens. That view treats store of value and medium of exchange as stages that can overlap rather than functions that must mature simultaneously. It contrasts with arguments that Bitcoin payment adoption remains too limited to support claims of broad everyday monetary use, especially when speculation and institutional activity still dominate transaction demand.
