90D Coin Days Destroyed (90D CDD) Indicator (Chart Tutorial)

TL;DR

• 90D Coin Days Destroyed (CDD) measures the total coin days destroyed over a rolling 90-day period, smoothing out daily noise.
• High 90D CDD signals sustained spending of older coins — often distribution, profit-taking, or reactions to macro events.
• Low 90D CDD reflects long-term holder dormancy — accumulation, conviction, or reduced sell pressure.
• This metric is ideal for macro cycle analysis, holder behavior tracking, and structural market shifts, without short-term volatility.

90D Coin Days Destroyed Indicator (Chart Tutorial)

The 90D Coin Days Destroyed (CDD) indicator is a smoothed version of the traditional Coin Days Destroyed metric, designed to highlight long-term holder behavior and market cycle transitions.

While daily CDD can be noisy and reactive to short-term movements, the 90-day rolling version filters out this noise and surfaces structural supply dynamics driven by older coins entering circulation.

As a result, 90D CDD is particularly useful for identifying macro shifts that are not immediately visible in price action.

What Is 90D CDD? (Simple Definition)

To understand 90D CDD, it helps to start with the fundamentals.

Coin Days

• Coin Days = coins × days unspent

Coin Days Destroyed

• When coins move, their accumulated coin age is erased
• Older coins destroy significantly more coin days when spent

90D Coin Days Destroyed

• 90D CDD aggregates all coin days destroyed over a rolling 90-day window
• Each data point reflects three months of long-term supply activity

Key Insight: The 90-day smoothing makes this metric far more reliable for identifying long-term behavioral trends than daily CDD.

Why 90D CDD Matters for On-Chain Analysis

The strength of 90D CDD lies in its ability to separate signal from noise.

Why Analysts Rely on It

• Filters out short-term coin movement
• Captures sustained spending of older coins
• Reflects long-term holder conviction or hesitation
• Helps identify market phases:
  
  • Accumulation
  • Distribution
  • Transition
• Strongly correlated with macro cycle changes

Insight: Sustained long-term holder behavior over a 90-day period often precedes major shifts in market sentiment.

How to Read the 90D CDD Chart

Interpreting the chart requires focusing on trends, not isolated spikes.

High 90D CDD

• Older coins being spent consistently over weeks or months
• Distribution during extended rallies
• Reactions to market stress or macro events
• Structural activity from large, long-term holders

Low 90D CDD

• Older coins remain dormant
• Long-term holders accumulating or waiting
• Reduced sell-side pressure
• Calm or early recovery phases

Key Signals to Monitor

• Multi-month peaks
• Extended troughs
• Inflection points
• Divergences between price and 90D CDD

What High 90D CDD Means

Elevated 90D CDD readings indicate persistent distribution of older supply.

High 90D CDD Often Reflects

• Long-term holders realizing profits
• Sustained sell-side pressure
• Distribution phases near market tops
• Macro-driven reallocations

Why It Matters: Short-lived spikes can be ignored — prolonged elevation signals structural supply changes.

What Low 90D CDD Means

Low readings are often associated with strong holder conviction.

Low 90D CDD Typically Indicates

• Minimal movement from long-term holders
• Accumulation behavior
• Reduced selling pressure
• Market stabilization following capitulation

Insight: Extended periods of low 90D CDD frequently align with the early stages of long-term bottoms.

Understanding the Rolling 90-Day Window

The rolling window ensures the indicator reflects consistent behavior.

Why This Matters

• Smooths volatility
• Reduces overreaction to short-term events
• Highlights sustained supply dynamics
• Provides a macro-level view of coin movement

Example

If older coins move aggressively for a short period, the effect persists across the full 90-day window, signaling deeper structural behavior.

Historical Patterns in 90D CDD

Across multiple cycles, 90D CDD exhibits repeatable characteristics.

Bull Markets

• Elevated 90D CDD
• Long-term holders distribute into strength
• Peaks often coincide with cycle tops

Bear Markets

• Suppressed 90D CDD
• Prolonged accumulation
• Dormant supply reflects weak sell interest

Transitions

• Rising 90D CDD during early recoveries
• Sharp declines after capitulation
• Trend reversals in 90D CDD often precede price reversals

How Traders & Analysts Use 90D CDD

Practical Applications

• Identifying distribution phases
• Confirming accumulation zones
• Assessing long-term holder sentiment
• Tracking structural supply shifts
• Supporting strategic, multi-month positioning
• Validating macro market narratives

Limitations of the 90D CDD Metric

Important Considerations

• Reduced sensitivity to short-term price action
• Does not identify individual wallets or entities
• Small movements of very old coins can distort readings
• Best used alongside price, volume, and supply metrics
• Inherently lagging due to its rolling nature

Pro Tips for Using the 90D CDD Chart

• Focus on trend changes, not absolute values
• Monitor prolonged low readings for accumulation
• Treat sustained uptrends as potential distribution
• Compare 90D CDD slope with price momentum
• Use high 90D CDD as a caution signal during rallies
• Use low 90D CDD to identify structurally strong markets

Frequently Asked Questions (FAQ)

1. What does 90D Coin Days Destroyed measure?

The total coin days destroyed over a rolling 90-day period, representing long-term holder spending behavior.

2. Why use a 90-day version instead of daily CDD?

It removes short-term noise and reveals deeper structural trends.

3. What does high 90D CDD mean?

Sustained spending of older coins, often associated with distribution or market stress.

4. What does low 90D CDD mean?

Dormant long-term supply, typically signaling accumulation or stability.

5. Does 90D CDD predict market tops or bottoms?

Not directly, but historical extremes often align with cycle transitions.

6. Can very old coins distort the metric?

Yes — older coins carry disproportionate weight due to accumulated age.

7. Is 90D CDD suitable for long-term analysis?

Yes. It is one of the most effective macro-level on-chain indicators.
