Entity-Adjusted Long-Term Holder CDD sums transferred BTC multiplied by coin age for the long-term holder cohort after filtering identified internal movements. It is measured in BTC-days, with cohort allocation based on age weights centered around 155 days rather than a strict age gate for every output.
Higher values indicate more long-term-holder age being spent, combining transfer size and age. On July 29, 2019, this cohort accounted for about 256.7 million of the 259.9 million entity-adjusted BTC-days spent overall, showing how strongly mature holdings can dominate total CDD.
A large old position moving once can outweigh many smaller transfers; the reading is not the number of BTC transferred or the number of holders exiting. Entity classification and smooth cohort weights affect the split, and cross-entity custody movements can add age expenditure without a sale.
Age multiplies the BTC amount. A modest transfer held for years can destroy more coin days than a much larger transfer held briefly, giving mature holdings an outsized influence.
LTH CDD adds up BTC amount times age. LTH ASOL averages eligible output ages without BTC-volume weighting, so one measures total age expenditure while the other describes the age mix of outputs.
No. Unspent holdings do not contribute to daily CDD. A low reading indicates little measured spending from the cohort, not an absence of long-term supply.
