Bitcoin Economics

Bitcoin is defined by a fixed 21 million BTC supply and a code-predetermined "rules-based monetary policy," with its scarcity, durability, and divisibility fueling debate over its potential as a "digital gold" store of value. Critics point to high volatility, its short history, and the unresolved question of the security budget once the subsidy fades, while estimates of how many people hold Bitcoin range from roughly 100 million to 500 million depending on the definition — suggesting adoption remains in an early stage.
