Accumulation Trend Score by Wallet Size (30D) summarizes 30-day balance accumulation separately for six size cohorts, from <1 BTC to >10k BTC. Each group has a normalized, unitless score from 0 to 1; these are independent scores, not BTC amounts or shares of a common total.
Higher scores identify groups with stronger accumulation over the monthly window; divergence shows whether that behavior is concentrated in particular balance sizes. On October 17, 2026, 100β1k BTC scored about 0.769 versus 0.263 for 1β10 BTC, a contrast that an aggregate score would conceal.
The 30-day window smooths shorter changes and may remain elevated after recent accumulation slows. Cohort membership can change with balances, and the exact weighting is not specified; neither a simple average of the six scores nor a score multiplied by holdings recovers the overall score or BTC accumulated.
It is identified as a separate 30-day accumulation measure, not as a moving average of the 7-day series. Without the underlying formula, the two should not be treated as mechanically interchangeable.
No. Each cohort uses its own 0β1 score, so several groups can have high readings at the same time. They are not percentages allocating one pool of supply.
It identifies a large-balance cohort. Exchanges and custodians can hold pooled funds, while a single investor can spread coins across smaller addresses, so the label does not establish individual ownership.
