BTC: Spent-Value-Weighted Dormancy — 30 Days

Bitcoin Dormancy (30 Days) was 14.8 days on 7 Nov 2026 (latest daily value).

Bitcoin's dormancy: the average age of the coins spent over the last 30 days, weighted by how much was spent.

Why use it. High dormancy means old coins are moving, often long-term holders selling; low dormancy means mostly young coins are changing hands. How to read it. It is in days. Large spends count more than small ones. It is not how long a person held, and moving coins does not prove a sale.

Calculation. Exact definition: The BTC-value-weighted age of outputs spent across the trailing 30 adjacent UTC daily observations. Large spent values carry more weight than small ones, unlike unweighted ASOL/MSOL. This is not an average of daily dormancy values, an owner holding period or evidence of a sale. The plotted day is included; zero total spent value, missing days or incomplete warm-up are undefined. Divide the sum of 30 daily header-time CDD values by all spent BTC in the same 30-day window, using retained local canonical block and undo facts. Ages are max(0, spend-header time − creation-header time) / 86,400. Preserve full input coverage and weakest partial/final quality.
