Cumulative Value Coin Days Destroyed (CVDD) adds up daily CDD multiplied by the contemporaneous BTC price, then divides by market age in days and a calibration factor of 6 million. The result is displayed in USD per BTC as a long-term model reference, not as the daily amount of destroyed coin age.
CVDD rises as cumulative price-weighted age spending grows relative to the elapsed-time denominator; a narrowing gap from BTC price means spot is approaching the model. Its level was about $14,834 on October 17, 2022, and about $20,524 at the April 2024 halving, showing how the reference shifts as spending history accumulates.
The 6 million factor is a model calibration, not a Bitcoin protocol constant, and internal transfers can add USD-valued CDD without a sale. Lifetime aggregation makes the line slow to reflect new conditions; it does not establish a guaranteed price floor or a target for subsequent price moves.
It first values destroyed age at the BTC price when that age is spent, then applies time normalization and a calibration factor. That construction produces a dollar-denominated reference rather than a raw CDD series.
Both build on cumulative USD-valued CDD and market age. CVDD uses a fixed 6 million calibration factor, while Transferred Price uses circulating supply in its denominator, so their levels differ.
The numerator accumulates nonnegative values, but the elapsed-time denominator also grows. The formula does not mathematically require the final ratio to rise every day.
