Orbuc is a digital asset research and investment firm. Orbuc produces its own data, tracking two core datasets independently — no third-party aggregators:

Bitcoin Institutional Holdings — compiled from SEC EDGAR 8-K filings, on-chain Etherscan data, and verified public disclosures across 6 segments (ETF funds, public companies, governments, private companies, DeFi/wrapped BTC, exchanges & custodians). Updated daily at 02:00 UTC.
