Lifespan CDD CDD
Bitcoin
Coin Days Destroyed (CDD) sums the coin-days erased when coins are spent, weighting movement by holding time.
Why it matters
It emphasizes the significance of old-coin movement over young-coin churn.
How it is built
Each spent coin is multiplied by the days it was held, and these are summed.
What to watch
Spikes signal long-dormant supply reactivating, historically a distribution warning near tops.
