Introduction to Coin Days Destroyed (CDD)
CDD (Coin Days Destroyed) is a refined version of the traditional Bitcoin transaction volume metric. It improves upon basic transfer tracking by incorporating time-weighted token movement analysis.

Key Concepts:
- Coin Days:
Token Amount × HODL Duration (in days) - Destroyed Coin Days: When tokens move after accumulation, their stored coin days are "destroyed" (logged as CDD).
- Smart Money Insight: Long-held BTC movements often signal experienced holders reacting to market shifts.
How CDD Works: Technical Foundations
UTXO Mechanism Explained
Bitcoin uses Unspent Transaction Outputs (UTXOs) instead of account balances:
- Each wallet's balance = Sum of all its UTXOs.
- Transfers consume UTXOs, triggering CDD calculations.
Building a CDD Dashboard
1. Core Components
Historical Trends
- Long-term CDD charts (years)
- Recent 30/60-day CDD snapshots
Anomaly Detection
Hourly Breakdowns
- Pinpoint exact timing of CDD spikes.
Wallet-Level Analysis
- Distinguish between single-wallet vs. broad-market movements.
Transaction Forensics
- Investigate specific TX IDs causing fluctuations.
2. Advanced Segmentation
| Analysis Type | Purpose |
|---|---|
| Exchange-Bound TXs | Identify sell pressure |
| Smart Money Wallets | Track "whale" behavior |
| Age-Banded CDD | Separate old/new coin movements |
Practical Applications

- Pre-crash CDD surges signaled accumulation/distribution.
- Hourly data revealed coordinated sell-offs.
- Wallet clustering exposed institutional participation.
FAQ
Q: Why does CDD matter more than raw transaction volume?
A: CDD weights transactions by holder duration, filtering out "noise" from frequent small transfers.
Q: How often should I check CDD?
A: For traders, daily monitoring. Investors can track weekly trends.
Q: Can CDD predict price movements?
A: Not directly, but sustained high CDD often precedes volatility.
