BITCOIN SUPPLY ADJUSTED COIN DAYS DESTROYED (CDD) CHART
What is the Bitcoin Supply Adjusted Coin Days Destroyed (CDD) Chart?
BTC supply Adjusted CDD (Coin Days Destroyed) refines the standard CDD metric by dividing it by the circulating supply. This adjustment removes the impact of supply growth, creating a purer, long-term indicator. It measures the economic activity of long-term holders relative to the total supply, offering a clearer signal on HODLer sentiment. High values suggest long-term holders are selling, while low values indicate strong accumulation.
Supply-Adjusted Coin Days Destroyed (SA-CDD) normalizes the raw CDD figure by Bitcoin's current circulating supply. Because the total supply of Bitcoin grows over time through mining, raw CDD will naturally be higher in later periods simply because there are more total coin days available to destroy. Dividing by circulating supply removes this growth bias and makes the metric comparable across Bitcoin's entire history.
SA-CDD isolates the behavioral signal from supply growth noise. When SA-CDD is elevated relative to its historical average, it signals that long-term holders are moving an unusually high proportion of their held supply — a pattern associated with distribution near cycle tops. When SA-CDD is very low, the opposite is true: coins are aging quietly, long-term holders are not selling, and the market is in an accumulation or consolidation phase.
The metric is particularly useful for comparing distribution events across different epochs of Bitcoin's history without the distortion that raw CDD introduces. A high CDD reading in 2024 is not directly comparable to a 2016 reading because the 2024 circulating supply is roughly 40% larger. SA-CDD corrects for this, enabling apples-to-apples comparison.
SA-CDD works best as a trend indicator rather than a level indicator. Sustained rises above its historical average during a price uptrend signal that experienced holders are using the rally to exit — a caution signal. Sustained lows during a price downtrend signal conviction holding, a historically bullish setup. Pair with NUPL, MVRV Z-Score, and raw CDD for a complete picture of holder behavior.
