As the cryptocurrency market continues to evolve, understanding investors’ behaviour becomes increasingly crucial. One valuable metric that sheds light on this behaviour is Coin Days Destroyed (CDD).

In this article, we’ll explore CDD, how it’s calculated, and why it’s important for investors and market analysts. So, let’s get started!

What Is Coin Days Destroyed (CDD)?

Coin Days Destroyed (CDD) measures the value of a cryptocurrency asset spent and its inactive duration. To calculate CDD, multiply the asset’s value by the number of dormant days. CDD is often used as a market indicator to analyse investor behaviour, particularly the actions of large holders, or “whales,” who can significantly impact the market.

Here are the key things you need to be aware of:

  • Measurement of Dormancy: CDD assesses how long a crypto asset stayed inactive before being moved. It is calculated by multiplying the number of dormant days by the asset’s value at the time of the move.
  • Behavioural Analysis: This metric helps study the actions of long-term investors in response to current market conditions and to anticipate future trends.
  • Market Activity Indicator: A high CDD suggests that long-dormant assets are re-entering the market, while a low CDD indicates that the trading volume consists of regularly traded assets.
  • Binary CDD: This metric compares the adjusted CDD to the total supply and the average CDD for that asset, providing insights into market strength.

Why Is CDD Important?

The daily transaction volume of a crypto asset is often used to gauge its financial viability. A peak in this volume is typically interpreted as an influx of buyers and sellers. However, this measurement needs to be more accurate. Coin Days Destroyed (CDD) offers a more nuanced view by examining the unspent transaction output (UTXO) for assets entering the market, considering both the transaction value and the number of days the asset remained dormant.

An unspent transaction output (UTXO) refers to the remaining amount of digital currency after a cryptocurrency transaction has been completed. It is similar to the change you receive after making a purchase.

By computing CDD values, we obtain a more accurate reflection of the rate at which new sellers or assets enter the market. These metrics complement daily transaction volumes, providing a more informed measure of market strength and offering insights into the behaviour of long-term holders and whales.

How to Calculate Coin Days Destroyed (CDD)?

CDD is calculated by multiplying the value of the asset spent by the number of days it has remained dormant. For example, in a recent transaction, an investor moved about 278 BTC, which had been dormant for 10.5 years, or approximately 3,833 coin days (excluding leap years).

Upon confirming the transaction, the Coin Days for these 278 bitcoins reset to zero. The CDD is determined using the formula:

CDD = Value sent × Coin Days

In this instance:

CDD = 278.89 × 3,833 = 1,068,985.37 ≈ 1.07 million CDD

Now, let’s explore how investors can utilise this CDD information.

How to Use Coin Days Destroyed (CDD) as an Indicator?

CDD calculations are sensitive to the movement of high-value assets and assets that have been dormant for extended periods. Here’s how to interpret CDD values:

  1. Short-term High CDD: A sudden spike in CDD alongside increased trading volume indicates that long-term investors are selling part or all of their assets to make profits. This is usually accompanied by increased on-chain activity for that asset.
  2. Sustained High CDD: When CDD remains high along with daily trading volume over an extended period, it signifies increased market strength. This is often seen in bull markets or during bearish conditions when long-term investors exit due to market conditions or protocol-related issues.
  3. Short-term Low CDD: A low CDD with increased or stable daily trading volume suggests that investors are holding onto their assets. The trading volume is influenced by the usual liquid assets. On-chain activity remains low despite changes in daily volume.
  4. Sustained Low CDD: A prolonged period of low CDD indicates growing investor confidence, with investors choosing to hold their investments longer. This is viewed as a bullish signal, suggesting a market reversal after a correction, as the rate at which dormant assets enter the market has slowed.

Supply-Adjusted CDD and Binary CDD

While Coin Days Destroyed (CDD) typically measures the movement of coins based on their dormancy, supply-adjusted CDD incorporates the total supply of tokens into the calculation.

Supply-adjusted CDD considers the total supply of an asset relative to the calculated CDD. As more crypto assets are issued through mechanisms like mining, vesting unlocks, or staking rewards, the CDD increases. Supply-adjusted CDD corrects for this by considering the impact of each token in circulation on the overall CDD. It is calculated by dividing the CDD by the total supply.

​Binary CDD compares the supply-adjusted CDD with the average CDD, representing the results as 1 (one) or 0 (zero). If the supply-adjusted CDD is higher than the average, it is described as 1; if it is lower, it is defined as 0. A sustained binary CDD of 1 indicates a bullish market trend while alternating binary CDD values (zeros and ones) suggest a bearish trend.

Conclusion

Investor behaviour is central to speculative trading metrics like CDD, which analyses the actions of long-term holders versus short-term holders to gauge market strength. Long-term holders, often considered ‘smart money,’ are crucial in CDD studies because their decisions to move assets after prolonged periods are usually influenced by significant events.

CDD metrics are valuable for routine traders and long-term investors. They highlight when dormant assets re-enter the market, which can signal important market changes. However, it’s essential to combine CDD with other market metrics to form a well-rounded trading strategy. Always practice risk management, and remember that this information is educational, not financial advice.
