Days Since ATH
Days since the all-time high counts the elapsed time since the last record close — a measure of cycle age, nothing more.
230 days have passed since the all-time-high close of $124,824 on 2025-10-06. This counts elapsed time only and says nothing about what comes next.

How it's computed
For each day, count the days elapsed since the most recent all-time-high close, resetting to zero whenever a new high prints. It counts elapsed time only and carries no valuation bands. Computed off the daily close through the latest available row in btc-history.json (a price-only community feed that trails the live market by roughly 30 days); the tail therefore lags today by about a month.
