Coin Days Destroyed (CDD)
A metric that weights coin movements by how long they sat idle — surfacing when old, strong hands finally transact.
Coin Days Destroyed weights each transaction by the coins’ value and how long they’d been dormant: a coin unmoved for a year accumulates 365 “coin days,” all “destroyed” when it finally moves. It filters out the noise of coins shuffling rapidly and highlights meaningful activity by long-term holders.
A spike in CDD means old, patient coins are moving — historically significant, since long-dormant holders awakening often precedes distribution near cycle tops. Low CDD suggests conviction holders are sitting tight. It’s a more sophisticated activity gauge than raw volume, because it asks not just how much moved but how strong the hands were that moved it.
