Phase 6 Recap

Part 6 of 9 — Security & Self-Custody — complete.
Part 7 of 9 — How Bitcoin Works — starts tomorrow.

Thirty days. The complete security layer. Here’s what was built.

The case for self-custody: every major exchange failure in Bitcoin’s history followed the same pattern. Centralised platform, customer funds at risk, market conditions change, withdrawals freeze. The Bitcoin network never failed. The businesses built around it did.

Hardware wallets: private key stored completely offline. No remote attack can reach what isn’t connected to the internet. Buy from official manufacturer websites only. Setup takes twenty to thirty minutes.

Seed phrases: 12 or 24 words that reconstruct your wallet on any compatible device. Store offline, physically secure, separately from the device. Never digitally. Consider steel for larger amounts. Consider a second copy in a different location.

Passphrases: an optional 25th word that creates a separate, hidden wallet. Powerful additional protection. Adds complexity. Losing it means losing access permanently.

Inheritance: two parts, kept separate. A letter pointing to the seed phrase location — no private keys in the letter itself. The seed phrase stored separately. A trusted person who knows what to do.

Scams: fake hardware wallets are defeated by buying from official sources only. Social engineering is defeated by one rule — nobody legitimate will ever ask for your seed phrase.

Advanced: multi-sig for significant holdings, watch-only wallets for monitoring without risk, privacy basics, DYOR at every level, node running for the technically inclined.

The security checklist covers everything. Tick it off and the Bitcoin is as protected as it can be.
