About CoinBucha.

CoinBucha is kept by Jukka Blomberg (jukkablomberg.com), with software agents doing the daily reads and refreshes he directs. The site has been published since 2026-06-08; the Listed Bitcoin Index since 2026-09-22, re-based to 100 on 2026-10-09 under methodology v2.0.

52 listed companies that hold bitcoin, each with its holding as filed, the share count, bitcoin per share and the next results date (Companies); 28 of them form the Listed Bitcoin Index. 5 US spot bitcoin ETFs with their issuers' own holdings (ETFs), never index constituents. An investor calendar and a results register. Government bitcoin reserves (Sovereigns) and the non-price adoption signals — sovereign adoption, corporate treasuries, hiring and hashrate (Signals).

No technical analysis, no price forecasts and no advice: nothing here says whether to buy, hold or sell anything, and no ratio is called cheap or expensive. No copy of an aggregator's holdings table: every holding is read from the holder's own filing or disclosure. Information, not financial advice.

A holding comes from the company's own filing or disclosure, or the ETF issuer's own daily holdings, with the date it is stated at and a locator — the form, the section or the file row — on the page that prints it. Aggregators are a lead source, never a figure (index rule R1). Share counts come from filings; closes are dated. Arithmetic such as bitcoin per share is printed with the dates of every input. Rules in full: index methodology.

A wrong figure is corrected in place and logged with its date, what changed and why, in the corrections log. Index membership changes only at a scheduled review, announced in advance. To report an error, write to hello@coinbucha.com with the page and the source.
