Yep, it’s a tough problem.

Hardware wallets breach privacy because they look like bitcoin / crypto devices and disclose to border guards that you’re holding something (for people who travel a lot and have no fixed base). IMHO for digital nomads it’s better to use ephemeral offline operating systems like tails.

Using a company like Unchained solves inheritance but breaches privacy because they are a honeypot and do KYC on their clients.
