Bitcoin held on the balance sheets of tracked public companies, in aggregate and by largest holder. Takes no arguments. Returns { as_of, total_btc, company_count, total_value_usd, top[], why, disclaimer, attribution, source_terms }, where top[] lists the largest holders as { name, symbol, btc }. Example: {}. CoinGecko values carry attribution: "Powered by CoinGecko" and source_terms. Information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }. This server answers bounded questions, one question, one answer; for bulk, history, backfills and scheduled pulls use the CSVs and datapackage.json at https://coinbucha.com/data.
