Definition. The total realized loss, segmented by holding-period age cohort. Realized loss is the summed difference between acquisition price and sale price across all spent coins where the sale price was lower than the acquisition price. Cohorts span from hot supply (most recently acquired) to cold supply (long-dormant coins). Realized Profit by Age is the profit counterpart. Realized Loss is the related base variant without segmentation.

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. Profit and loss are measured against each address's average acquisition price. 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 realized losses concentrate across hot-to-cold age cohorts. Answers questions of the form: is total realized loss greater for hot or cold supply?
