Privacy as a Shield: Strengthening Security Through Bitcoin and Self-Custody
summary
Privacy reduces attack surface by increasing the cost of attack and lowering the cost of defense, so combine self-custody with concrete tools: use a hardware wallet (Coldcard, Coinkite, Foundation Passport, Blockstream J Plus) plus multi-signature and a strong passphrase, run a personal full node on Start9 with Grafinos phones, keep secrets off Windows, and create physical backups with the automatic steel engraver Seat Hammer that engraves seed words and airgapped via QR codes or NFC Shamir shares in ~30 seconds.
