Overview
Coin Days Destroyed (CDD) measures both transaction volume and the age of coins moved.
Each coin accumulates one “coin day” per day it remains unspent. When spent, its accumulated days are “destroyed”.
This helps identify when dormant coins re-enter circulation, revealing holder confidence or capitulation.

Interpretation

• 📈 High CDD → long-term holders are spending, often marking distribution or profit-taking phases.

• 📉 Low CDD → coins remain dormant, suggesting accumulation or investor conviction.

Formula

$CDD = \sum_{i=1}^{n}(Value_i \times Age_i)$

$CVDD = \frac{CDD}{Total\ Supply}$

Signal

• Rising CDD: potential market tops, selling pressure.

• Falling CDD: accumulation or market confidence.

Insights
CDD filters noise from frequent trading and isolates meaningful economic activity.
Its derivatives (Supply-Adjusted, Binary, or Terminal Adjusted CDD) refine signals for specific market phases.
