We've seen thousands of bitcoin security setups. A small number of them would survive a real test. Here's what those have in common that most others don't:

First: multiple keys, multiple vendors, multiple locations. Different hardware across keys matters as much as the distribution. A supply chain compromise or firmware vulnerability in one vendor shouldn't touch the full setup. One key lost, stolen, or destroyed; the bitcoin is still accessible.

Second: tested recovery. They've wiped a device and rebuilt from seed only. Or bought a second device, rebuilt from seed, and confirmed access. The process works because they've walked through it. A setup that has never been tested is a hypothesis.

Third: a documented inheritance plan. If they died tomorrow, a non-technical family member could access the bitcoin. The plan is written, tested, and executable by someone who has never touched a hardware wallet.

Fifth: a review cycle. A setup built for the position you held in 2022 may have real gaps today. Positions grow. Life changes; a new family member, a new location, a different threat landscape. Security gets revisited on a schedule, not when something goes wrong.

The common thread across all of it: they treat security as a living system; something built, tested, and maintained over time. A hardware wallet is a component. A seed phrase backup is a component. A tested, distributed, documented architecture is something different.
