The Cumulative Value Days Destroyed (CVDD) metric has historically called Bitcoin price cycle lows almost to perfection across every cycle since Bitcoin's inception. This metric begins with Coin Days Destroyed, a measure that weights Bitcoin transfers by the duration they were held before movement. For example, holding 1 Bitcoin for 100 days produces 100 coin days destroyed when transferred, while holding 0.1 Bitcoin for the same result requires 1,000 days of holding.
