Definition. The total volume of BTC spent at a profit (sale price above acquisition price), segmented by wallet-size cohort from large holders down to small retail balances. The breakdown shows how realized-profit volume is distributed across investor classes. Spent Volume in Loss by Wallet Size is the loss counterpart, and Spent Volume by Wallet Size is the total.

Technical. Breakdowns use an address-based approach, analyzing transactions and holdings at the wallet-address level. This contrasts with the UTXO-based approach available for some chains, and cross-method comparisons may show small deviations. An address's wallet-size band is set by its balance before the spend. 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 profit-making sale volume concentrates across investor classes, from whales down to retail. Answers questions of the form: are larger wallets (whales) selling their coins at a profit more frequently than smaller wallets (retail investors)?
