The age of the coins that move, day by day
The average age of the coins being spent each day, over the years. Higher means older, long-held coins are on the move; lower means fresh coins are doing the trading. Hover or tap for the exact reading.
Price uses its own log scale on the right. Compare timing, not vertical distance.
Inspect and compare dates
Pick two to four dates to compare the reading.

Right now
Coins held for years are changing hands in force. The reading is long-dormant coins on the move.
It has sat above the 90th percentile of its four-year range for 4 days running.
That kind of spending by long-time holders has clustered near past tops.
Last four years
Smoothed over about a week the reading is 97.7 days, which sits at the 92nd percentile of the last four years, near the old-coin end of it.
The coins moving are much older than the average across the whole record. The chart draws the raw daily reading, 77.6 days on the latest day, which swings wider than the smoothed one.
What changed
The daily reading rose from 48.3 days to 77.6 days over the past month, since 12 Oct 2026. Over the past week the coins moving got younger, so fresher supply did the trading.
A rising line means older coins are on the move. A falling line means fresher coins are doing the trading.
What would change this read
If older coins start moving and this climbs, people who have held a long time would be spending, something that has often shown up near past tops. If it stays low, long-held supply keeps sitting still, which keeps those coins off the market.
The reading is already on the old-coin side. The thing to watch is whether this is steady profit-taking or the start of something heavier.
How to use it
Read this as a trend over weeks, not a single day. One large old-coin payment can lift a day’s reading on its own.
It says how old the coins moving are, not who moved them or why, and a coin moving between two wallets owned by the same person counts the same as a sale.
Understanding
ASOL (Average Spent Output Lifespan)
Where it stands today
Smoothed over about a week, the Bitcoin moving is 97.7 days old on average, which reads as long-dormant coins on the move as of .
What does this chart measure?
ASOL, or Average Spent Output Lifespan, looks at every coin that moves on a given day, measures how long it had been sitting still, and averages those ages. A low number means the coins being spent are young. A high number means long-dormant coins are on the move.
What does a low reading mean?
Recent buyers are doing most of the trading and patient holders are keeping their coins put. That keeps long-held supply off the market, which is usually a calm backdrop where people are buying steadily rather than selling.
And a high one?
Coins that sat untouched for months or years are suddenly changing hands. That is people who have held a long time spending into strength, a pattern that has clustered around major tops as patient money takes its profit.
Why does the page show two different numbers?
The chart draws the raw reading for each day, which is the honest picture of a measure that jumps around. Where the page ranks today against the last four years it uses the reading smoothed over about a week, because a single busy day would otherwise decide the rank. The two can differ by a lot, so each one is labelled where it appears.
What can it leave out?
It is a noisy, day-to-day measure, and one large old-coin payment can spike it. It also cannot tell a sale from a holder moving coins between their own wallets. Read it as a trend over weeks, alongside the other holding and old-coin gauges. See the full age map of the supply.

Daily readings since 1 Jan 2011 let you compare the latest day with earlier months. Every reading is the average age of the coins spent that day, in days, as measured, not smoothed. Highest and lowest cover every reading since then; month-end values use the last reading on or before that date. The latest daily reading is 77.6 days, which the page reads as long-dormant coins on the move.
