Definition. The 30-day Accumulation Trend Score broken down by wallet-size cohort. The score reflects the relative size of entities actively accumulating coins on-chain over the past 30 days, combining each entity's balance size (participation score) with the amount of new coins it acquired or sold over that window (balance-change score). Accumulation Trend Score by Wallet Size (7d) is the 7-day counterpart. Accumulation Trend Score is the related base variant without segmentation.

Technical. For BTC, exchange and miner entities are excluded. For ETH, the score uses an account-based approach, smart contracts and the beacon deposit contract are excluded, and exchanges are not excluded. For ETH tokens, smart contracts, burn addresses and all exchange-labelled addresses are excluded, and wallet-size bands are shares of token supply rather than absolute balances.

Interpretation. A score near 1 indicates that on aggregate, larger entities within the cohort are accumulating, a score near 0 indicates they are distributing or not accumulating.
