Definition
Inflation is a sustained increase in the general price level across an economy, meaning that over time the same amount of money buys fewer goods and services. It is usually measured by index baskets such as the Consumer Price Index. Economists distinguish a one-off price jump from inflation proper, which is an ongoing year-over-year trend. The mirror image of rising prices is falling money value: as prices climb, the purchasing power of each currency unit declines.
What drives it
Mainstream accounts cite demand-pull pressure (spending outpacing output), cost-push pressure (rising input costs), and expansion of the money supply. Bitcoiners tend to emphasise the supply channel: when the quantity of money grows faster than the goods and services it can buy, each unit is worth less. This framing connects inflation directly to monetary policy decisions such as quantitative easing and to historical currency debasement.
Why miners and savers care
Inflation is the backdrop against which hard-asset narratives are argued. Bitcoin's issuance schedule is fixed and disinflationary by protocol: the block subsidy halves roughly every four years, and the supply cap is 21 million coins. Whether or not Bitcoin's market price tracks consumer inflation in the short run, its supply cannot be inflated by any issuer, which is the core of the sound money argument. For miners, inflation also affects real-world costs: electricity, hardware, and shipping prices all respond to the broader price level.
