Day 228Part 6: Security & Self-Custody

Bridge to Phase 7

Part 6 covered thirty days of Bitcoin security — the practical layer that makes self-custody real rather than theoretical.

The pattern of every exchange failure. Hardware wallets and why they matter. How to set up self-custody properly. Seed phrase storage, passphrases, and the options available. Inheritance planning — the letter, the separation, the trusted person. Scams and how they work. Multi-sig for larger holdings. Privacy basics. DYOR applied at every level. The complete security checklist.

By now, the Bitcoin in this journey is as protected as it can be — secured by a private key that only the right people can access, with a plan in place for every scenario that matters.

Part 7 is different. It goes under the hood.

For 226 days, Bitcoin has been discussed in terms of what it does — without explaining in detail how it does it. That was intentional. Understanding the properties came first. Using it came second. Protecting it came third. Only now — after all of that — does the technical layer earn its place.

Part 7 covers how Bitcoin actually works: private keys and cryptography, the blockchain, mining and proof of work, nodes, the mempool, transaction fees, and what happens when all 21 million Bitcoin are eventually mined.

None of it requires a technical background. It requires the context that the past 228 days have built.

See you in Part 7.
