Spent Outputs Aged 3m–6m totals the outputs consumed each day whose lifespans fall between three and six months. It measures output-level activity around a holding interval that spans the usual boundary between short-term and long-term holders, in outputs per day.
Higher readings mean more quarter-old outputs are being spent; declining readings mean fewer are moving out of that age window. The record of 363,485 on October 8, 2023 compares with a full-history median of 8,745, illustrating how a brief burst can dominate the scale.
This band straddles the roughly 155-day holder boundary, so it cannot be assigned entirely to short-term or long-term holders. Unadjusted self-transfers and consolidations may drive peaks, and raw output counts do not show the amount, gain or destination of the BTC involved.
It overlaps both under the usual roughly 155-day convention. Output lifespan and entity-level average acquisition age are also different methods, so the band cannot be mapped directly to one holder cohort.
Coin days destroyed weights spending by both BTC amount and age in days. This series gives each qualifying output one count, whether it contains little BTC or a large balance.
Yes. More coins can age into the unspent band while fewer outputs within it are consumed. Remaining supply and daily spending are separate measures.
