After spending about fifty hours researching Bitcoin hardware wallets via:
- Product documentation
- Twitter feeds
- YouTube videos
- Podcasts
- Reviews and comparisons
- Considerations of desired features
My conclusion is that:

Very long term cold wallet with single passphrase generation
Make it easier to create a wallet by requiring only:
- A good passphrase for it along with a Salt
- A WarpWallet implementation to rebuild it.
Not BIP-39 with a passphrase and yet
“as secure as BIP39 although much more convenient and user friendly.” ―Bitcoin Glossary#WarpWallet
Interesting idea gone into great detail here.
The bitkey air-gapped Bitcoin toolkit
bitkey is a
Bitcoin Swiss Army Knife in a verifiably secure self-contained Live CD/USB. Supports air-gapped Bitcoin transactions. Makes offline cold storage (slightly more) practical.
Very thoughtful explanation provides tips for reflection on how to manage custodial expectations on yourself and others.

First our own, then others.
Signs of a good teacher
If a teacher teaches you everything, then run; you won’t know how to learn.
After being told to do it, face it confront it, survive, then move on to the next one.
How did the first version of the Krebs Cycle look?
The answer is probably #1 radically different than the perfected version that we know and love today, and #2 is very fun to imagine.

12 or 24 Words in your BIP-39 Wallet? Use a passphrase or not?
On Sep 20, 2018:
If the attacker needs your 24-word seed and your passphrase, that is a good security mechanism. It means that if somebody finds your 24-word seed lying around, you shouldn’t have it lying around, but if they do find it and it’s not sufficiently physically secured, then brute-forcing it, brute forcing the password, will require either a lot of infrastructure or a lot of time. ―Andreas M. Antonopoulos
A relatively complex passphrase will keep you safe for several weeks, a month. A very strong complex passphrase will keep you safe for months; unless the person is willing to spend a million dollars on hardware to break that passphrase. ―Andreas M. Antonopoulos

Keeping Your Computer Safe and Usable by Verifying Downloads
When you install or upgrade software on your computer, try to make it safer.
It only takes a little effort and pays off big rewards in privacy and ease of mind. Although this example is on a Mac, it is general enough to translate to Windows or Linux easily.
