BITCOIN ASOL
How old are the coins that are moving?
When the coins changing hands are young, recent buyers are doing the trading. When old coins move, long-time holders are spending.
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.

What's the read right now?
A NORMAL MIXA typical blend of young and older coins is changing hands — nothing unusual in who's spending.
A noisy, day-to-day measure — one busy day can spike it. Read the trend, not a single reading.

≈ 37 days average age of the coins moving todayAbout usual versus its own averageWhat's changed recently?
- This past week the coins moving got younger — fresher supply did the trading.
- Over the past month older coins have been moving more — long-time holders are spending.
- Right around the middle of its 4-year range — a normal mix of ages.
What would change this read?
- If older coins start moving and this climbs, long-time holders 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.
Understanding ASOL (Average Spent Output Lifespan)
ASOL — 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.
When ASOL stays low, recent buyers are doing most of the trading and patient holders are keeping their coins put. That keeps long-held supply off the market — often a calm, accumulation-style backdrop.
When ASOL spikes, coins that sat untouched for months or years are suddenly changing hands. That's long-time holders spending into strength — a pattern that has clustered around major tops as patient money takes profit.
It's a noisy, day-to-day measure — a single large old-coin transaction can spike it. It's best read as a trend over weeks, alongside the other holding and old-coin gauges, rather than as a one-day signal.
