Spent Outputs Aged 7y–10y measures the daily number of consumed outputs created seven to ten years before the spend. It isolates very old output activity in a three-year-wide band, with no adjustment for the BTC held in each output.
A burst reveals that very old output records are being used again; long quiet stretches show little spending in this window. On April 27, 2025, the count reached 38,299 with BTC around $94,661, while the full-history median is zero, reflecting the long period before this age group could exist.
Seven-year-old outputs were impossible before 2016, so full-history percentiles overstate rarity relative to a mature-network sample. The wide age interval and wallet consolidation also affect counts; the metric cannot identify a particular early owner, prove a sale or tell how much BTC remains dormant.
The dataset starts in 2009, but no output could be seven years old before 2016. Combining that initial period with later sparse activity produces many zero observations.
No. The age only dates that output's creation. It may have come from mining, a payment or a wallet transfer; the count does not attribute ownership or origin.
No. This metric counts outputs, whereas age-band supply is measured in BTC or as a supply share. The BTC removed from the band depends on the balances of the spent outputs, and other coins can age into it at the same time.
