Spent Volume Aged 1h–24h is the daily sum, in BTC, of spent outputs that existed for one to 24 hours. It isolates intraday re-spending after the first hour and excludes both sub-hour outputs and those held longer than a day.
Growth in this band means more BTC is being spent after an hours-long pause, while a decline points to quieter activity in that window. Its 2022 maximum was about 1.29 million BTC on June 13, compared with about 202,891 BTC at the 2024 maximum. The size of these bursts can differ markedly across years without identifying their market direction.
Outputs are not investors: a service can generate many short-lived outputs, and the same BTC can circulate more than once. This is neither a 24-hour exchange trading volume nor a count of new purchases. Assess multi-day persistence and compare sub-hour volume before attributing a one-day jump to broader participation.
No. It only includes outputs whose lifetime before spending was one to 24 hours. Outputs held for weeks or years can be spent on the same day but belong to other age bands.
Read the under-1h and 1h–24h bands beside the daily and multi-month bands. A surge confined to the youngest bands shows fast circulation without establishing that older holdings have become active.
It sums the coin amount of qualifying outputs without multiplying by price. The dollar value of that activity can rise even when BTC volume falls if Bitcoin's price increases enough.
