Spent Outputs Aged 1h–24h is the daily number of consumed outputs whose lifespan was between one hour and 24 hours. Every qualifying output contributes one to the count, so the series measures within-day reuse after the very shortest-lived outputs are excluded.
Higher activity here means more outputs are being spent after waiting hours rather than minutes or days. The count peaked at 462,766 on April 21, 2023; on the April 20, 2024 halving date it was 230,731, demonstrating that different busy periods need not produce the same age mix.
The interval is elapsed time, not a calendar-day label, and outputs can cross midnight before being spent. Exchange operations and batched input consolidation can lift counts without new economic ownership, while the absence of BTC weighting makes this unsuitable for estimating the size of capital flows.
No. A qualifying output can be created late one day and spent the next. The elapsed interval between creation and spending determines its band.
Together the two bands cover outputs spent within roughly their first 24 hours. Their sum is still a count of outputs, not a count of unique coins, users or transactions.
A transaction may consume one input or hundreds of inputs. Spending many qualifying outputs in a few consolidation transactions raises this series without a similar rise in transaction count.
