About Bitcoin Security Guide

Bitcoin Security Guide is an educational resource about hardware wallets, seed backups, passphrases, privacy, multisig, inheritance, and physical security for people who want to hold their own keys.

Evidence standards

Security claims should link to primary documentation, public source code, incident records, or credible public research whenever those sources are available. Conclusions distinguish verified facts from inference and are revised when stronger evidence appears.

Editorial scope

• Bitcoin-only self-custody education.
• Hardware wallet setup, backup testing, and recovery planning.
• Operational security, privacy, inheritance, multisig, and physical security.
• No investment advice, price predictions, trading recommendations, or altcoin promotion.

Corrections

Security guidance changes. Pages are revised when primary documentation or credible public research changes, and material edits update the page date.

Product references
