About BTC Timeline

BTC Timeline is an independent information site tracking corporate Bitcoin treasury strategies. Focusing on Metaplanet (TSE: 3350) and Strategy (NASDAQ: MSTR), we organize holdings, acquisition histories, and investment amounts into timelines, available in Japanese, English, Korean, and Chinese.

  • Browse the full timeline of acquisitions (date, amount, price per BTC, total value)
  • Compare treasury strategies across companies
  • Export data in CSV / JSON formats

Data Sources

Transaction data is manually compiled from primary sources: official press releases, timely disclosures, investor-relations materials, and SEC filings. Live Bitcoin prices come from the CoinGecko API.

We update the data as soon as practicable after new transactions are announced.
