Mean Age 90d
Bitcoin
The Mean Age is the average age of all coins in the supply, weighted by coin amount.
Why it matters
It gauges overall supply maturity and holder behaviour across the network.
How it is built
Each coin is weighted by the time since it last moved, and the average age is computed over the window. This particular series is measured over the 90D window.
What to watch
Rising mean age reflects widespread holding and accumulation; falling age reflects spending and turnover.
