Definition ∞ BTC scarcity refers to the finite supply of Bitcoin, which is programmatically capped at 21 million units. This predetermined limit differentiates Bitcoin from fiat currencies, which central authorities can issue without constraint. The decreasing rate of new Bitcoin creation, known as halving, further contributes to its supply constraint over time. This inherent characteristic is a fundamental aspect of Bitcoin’s economic model, influencing its perceived value and price dynamics in the market.
Context ∞ The discussion around BTC scarcity frequently centers on its impact on Bitcoin’s long-term value proposition and its role as a store of value akin to digital gold. As more Bitcoin is mined and fewer remain available for acquisition, market participants often anticipate increased demand against a fixed supply, potentially leading to price appreciation. A critical future development involves monitoring the remaining supply and the effects of subsequent halving events on market behavior and adoption rates.
