Cumulative Bitcoin Coin Days Destroyed¶
What It Measures¶
Cumulative Bitcoin Coin Days Destroyed is the running total of all coin-days destroyed across Bitcoin’s history.
It answers a structural question:
How much dormant coin-age has the network spent away in total over time?
The logic is simple:
This series does not reset. It grows as the network destroys more accumulated age through spending.
That makes it different from daily CDD. Daily CDD shows what happened on a specific day. Cumulative CDD shows the long-term stock of destroyed dormancy.
How To Use It¶
On its own, Cumulative CDD is not usually a front-line chart for trading or cycle timing. Its main value is as a structural input to Liveliness.
That is because Liveliness compares:
- the total dormancy that has been destroyed,
- against the total dormancy the network could have accumulated.
So the practical use of Cumulative CDD is to provide the numerator in that long-run relationship.
It is most useful when the goal is to understand whether Bitcoin’s history has been characterized more by:
- preserving dormant supply,
- or spending it away.
What It Can Say About Market Regime¶
By itself, Cumulative CDD is too monotonic to function as a clean regime signal. It rises through time as more dormancy is destroyed.
Its real interpretive value appears when compared with the network’s cumulative supply-age base.
That comparison becomes Liveliness.
So while daily CDD helps identify bursts of old-coin activity, Cumulative CDD helps answer the broader question of how much dormant age the network has already spent through its full history.
Historical Background¶
Cumulative CDD follows naturally from Coin Days Destroyed itself. Once daily age-destruction became an established concept, the long-run cumulative series became the natural way to compare destroyed dormancy with accumulated possible dormancy. That long-run comparison is what later made Liveliness possible.
