> Bitcoin's public-market layer: which listed companies hold bitcoin, how much, from their own filings — and which governments hold it. CoinBucha publishes the CoinBucha Listed Bitcoin Index (LBTC, cap-weighted) and its holdings-weighted sister (LBTC-H), a dated register of listed companies holding bitcoin, and the Sovereign Bitcoin Reserve Monitor. Every figure carries its source and an as-of date. Information, not investment advice.
