Definition. The total volume of coins spent, segmented by holding-period age cohort. Cohorts span from hot supply (most recently acquired) to cold supply (long-dormant coins). Spent Volume in Profit by Age and Spent Volume in Loss by Age split this volume into profit and loss.

Technical. Breakdowns use an address-based approach, analyzing transactions and holdings at the wallet-address level to keep results comparable across digital assets and consistent across different blockchain architectures. This contrasts with the UTXO-based approach available for some chains (e.g. Bitcoin), and cross-method comparisons may show small deviations. Coin age is the time since the sending address's balance-weighted average acquisition time, so everything an address spends falls into a single age band. For BTC, ETH and ETH tokens, spends are netted per address per block, which removes change; for DOGE, TRX, XRP, TON and TON tokens, all transfers are counted. For ETH tokens, burn addresses are excluded.

Interpretation. Surfaces how total sale volume concentrates across hot-to-cold age cohorts, identifying periods of increased selling among different vintages. Answers questions of the form: are older coins being sold more frequently than newer ones?
