Definition. The amount of circulating supply last moved between 1 day and 1 week ago. HODL Waves is a related, normalized metric.

Technical. The supply shown here is the sum of all address balances, so the total across all age bands can differ from Circulating Supply. Except for BTC, coin age is the time since an address's balance-weighted average acquisition time (address-based approach), so each address contributes its full balance to a single age band. For ETH, the beacon chain deposit contract is excluded.
