BTC: Gross Output Value / Serialized Transaction Size - 365-Day Correlation

Bitcoin Gross Output Value / Serialized Transaction Size - 365-Day Correlation was 0.0928 correlation on 7 Nov 2026 (latest daily value).

How closely Bitcoin's daily on-chain volume and average transaction size moved together over the last year: a correlation from -1 to 1.

Why use it. It shows whether bigger transfers come with bigger transactions, such as batched payments. How to read it. Near 1 they rise and fall together, near -1 they move opposite ways, near 0 they are unrelated.

Calculation. Exact definition: The Pearson correlation between daily gross output BTC and daily mean serialized transaction size over 365 adjacent UTC days. Values run from -1 to 1: positive values mean the two daily series tended to move together, negative values mean they moved in opposite directions, and values near 0 mean little linear relationship; correlation does not establish cause. Gross output includes change and repeatedly moved value, so this population is not mean transferred BTC or identified economic transactions. Closed UTC days only; a missing or partial day in the window, or zero variance, leaves the value undefined. Pearson correlation of 365 adjacent daily observations of gross output BTC (input a, raw output volume) and mean serialized transaction size in bytes (input b). Exact finite-decimal centered sums are formed first, then 40-digit Decimal division and square root. Both inputs come from locally validated Bitcoin Core data; source revisions, publication holds and the weakest input's finality carry through.
