All values come directly from CoinGecko. We do not modify, smooth, or interpolate published values.
Live US dollar price for Bitcoin (BTC), sourced from CoinGecko. The first and largest cryptocurrency by market cap, often used as a digital store of value and inflation hedge. Price reflects weighted average across major exchanges.
Daily — we refresh every hour during US market hours; upstream publishes on business days.
We gate dateModified updates to actual value changes (threshold: 0.01% absolute or 0.5% relative) to prevent freshness spoofing. If the upstream value hasn't moved, we don't claim we updated the page.
