BTC Mapa de calor del coste base de tenedores a corto plazo: 227.9K
Where Bitcoin bought by recent holders is concentrated by price. Brighter horizontal zones contain more BTC that last moved at that cost basis; the black line is Bitcoin's daily close.
A time-by-price map of the bitcoin held by **recent buyers**. Each vertical slice is one UTC day; each horizontal cell is a narrow acquisition-price interval. Brighter cells contain more BTC whose current UTXOs were created inside that price interval.
Read the **black line** as Bitcoin's daily close and the coloured field as the cost basis underneath it. A bright band below price is a large group sitting in profit; a bright band above price is a large group sitting underwater. Tap or hover any day to see the exact price zone, BTC amount, share of STH supply and distance from spot.
A dense band can become an area holders watch, but it is **not automatically support or resistance** and does not predict the next candle.
For every live Bitcoin UTXO, keep the USD daily close from the day that output was created. On each UTC day, retain outputs younger than **180 days**, group their live BTC into logarithmic price buckets roughly 4.7% wide, and sum BTC per bucket. Colour intensity is log-scaled within the selected view and capped at its 95th percentile so one extreme cluster cannot bleach every other real zone.
Safu uses the same **180-day** boundary as its HODL and LTH/STH charts; this is not Glassnode's proprietary 155-day model. Cost basis uses the creation day's close rather than each intraday trade price, so it is a daily-resolution estimate from exact UTXO balances.
Historical heatmap cells exist only after our node has replayed and stored that day. Missing history is shown as unavailable — it is never backfilled from spot price or fabricated in the browser.
