Versions and changelog

Changelog

All notable changes to the Bitcoin Weigh-In dataset are documented here.

This dataset follows semantic versioning for breaking column changes

(major: removed or renamed columns; minor: added columns or sources;

patch: bug fixes that do not change schema).

v1.0.1 — 2026-05-17

Coffee unit normalisation (data correction). coffee_usd is now

expressed in US dollars per pound (previously: cents per pound, the

raw Stooq unit). coffee_per_btc is now correctly denominated in

pounds of Arabica coffee per BTC. Users of v1.0 should re-derive any

coffee-based analysis: previous values were 100× the correct figure.

Coverage start shifted to 2013-01-02. The 2013-01-01 row carried

only the BTC price (every other commodity column was empty, with no

prior close to forward-fill from). Removed for cleanliness; the

dataset now begins at the first complete row. Row count: 4,879.

SHA-256 sums updated to reflect regenerated artifacts.

v1.0 - 2026-05-17

Initial public release.

Raw daily USD closes for BTC, gold (XAU), silver (XAG), platinum (XPT),

copper (HG continuous), wheat (ZW continuous), coffee (KC continuous),

and Brent crude (FRED DCOILBRENTEU).

Derived per-BTC columns: xau_per_btc, xag_per_btc, xpt_per_btc,

copper_per_btc, brent_per_btc, wheat_per_btc, coffee_per_btc.

Deterministic BTC circulating supply computed from the halving schedule

(no API dependency).

Coverage: 2013-01-01 to present, daily.
Forward-fill: per-row provenance is not reconstructable from existing

data; the forward_filled column is present but populated as empty

string for all v1.0 rows. Prospective tracking will begin in v1.1.

Historical versions remain downloadable under /data/v1.0.1/ and any prior version directories.

Known limitations

Commodity values are forward-filled on market-closed days (weekends, public holidays, and source outages). v1.0 ships a forward_filled column populated as empty string for every row because per-row fill provenance is not reconstructable from the existing historical data; prospective per-row tracking begins in v1.1.

Pricing for Plutonium-238 and cocaine on the main visualisation is illustrative — engineering composites described on the methodology page — and is not included in this dataset, which holds only live market closes.

Pre-2013 data is unavailable across the commodity set at acceptable quality, so coverage begins 2013-01-02. Source outages and cross-validation flags from the secondary feed are logged at health.json.
