There is a video series on YouTube which is fantastic! I watched it just for fun, but I would to like to hear someone else's opinion on that, perhaps after actually trying it.

"Escape with your Bitcoin":

I only briefly see the 1st part ("Personal Server"). But since it involve using PGP and setting server where you access it with .onion rather than plain IP address, average people would find it challenging. You're expected to ensure the server remains on and connected to internet, before you move elsewhere and access it remotely. While you could rent VPS for that task, some trust is required even though you store the encrypted data (seed, pass, etc.).
