Very much depends upon timeframe Lyn:

If you’re looking to safely secure over a handful of years, hardware wallets are a good option and there are many to choose from

I contend they are a poor choice for long term (decades or generations) because hardware devices *and their interfaces* are notoriously short lived

If bitcoin had been around when i started in IT, the most secure storage was archive-quality mag-tape. Step back just a decade, and the best was likely CD/DVDs .. now think about the last two computers you acquired - does either have a DVD drive?

What about SD card readers? They were popular for a while and many computers included slots for them - today, not so much.

Core point is that todays hardware wallet, may be difficult to access in a decade or two simply because tech and interfaces evolve. As a recent example consider the new iPhone which has now finally switched to a standard USB-C port instead of the apple proprietary one.

So for short/medium term, hardware wallets are useful as signing devices, but never to be relied upon for long term security.

IMO, for that longer term security you must store the seed and passphrases on very low-tech solutions.

As long as BIP39 is supported by signing devices of the future, I don't think this is so much of an issue.

I see signing devices as a convenient way of recieving & spending bitcoin. If long term custody is required, you extract the xpub & wipe the signing device. Your seed words then become your only significant threat to exclusive access.

For the average user, I think the Bitbox 02 or Jade would be my recommended wallet.

I trust the Cold Card security more but I think the average user is better off with something simpler.

You can take your seed phrase from an old device and recreate the wallet in a new device when technology advances to the point your old device is difficult to use.

Absolutely!

So if you’re reviewing every 2-3 years and acting accordingly you’ll be fine

If you want to create storage for your unborn grandchildren that will survive half a century without intervention you’ll need a different approach

what kind of examples would you give for 'low-tech solutions'?

Seed words/passphrases punched into stainless steel washers or plates are about as durable and lowtech as it gets i think

Lopp has excellent reviews of seed storage devices against acid, fire and pressure tests - good proxies for time
