Coin Days Destroyed
What Is Coin Days Destroyed?
A metric weighing both the number of coins and how long they've been held. One coin held for 100 days then moved = 100 coin days destroyed. Gives significance to old coin movements.
How to Interpret
CDD spikes indicate old, high-conviction coins moving — often significant market events. Sustained elevated CDD can signal major distribution phases at cycle tops.
