Antwort auf: Die beste Art, Seed Phrase zu speichern
There’s no single answer, it’s like asking „What’s the best car?“ Well, it depends…
Best practice is to never save it digitally, not even encrypted or a photo. That’s one rule I would always adhere to. And that also means, never type the seed in any device other than the hardware wallet itself if you need to restore or want a second device as backup.
There was recently a case of hacked Metamask wallets and the surprising thing was that many of those people who got hacked were OGs and haven’t had moved their funds or signed contracts in Metamask, so there must have been another exploit. And as it turned out, what they had in common was they saved their seed in LastPass, which got hacked and apparently the hackers were also able to decrypt the user data.

Another common mistake is that people don’t use well-tested best practices to safe their seed but instead come up with their own overly complicated methods and then they end up not being able to restore or find the seed. Some guy had a large amount of Bitcoin in a wallet he lost, and the seed was saved on a Kingston IronKey thumbdrive that deletes itself after 9 wrong entries. The guy forgot the password.
Someone else had their seed hidden with his fishing lures in a shed. This too was a large amount of Bitcoin. Somehow he forgot about it, the shed later got cleaned out and years later his Bitcoin would have been worth many millions.
So yeah, user error is a serious threat.
I got 2 hardware wallets with the same seed, in case one breaks. And I got the seed split in 3 pieces in different locations (one is a bank vault). I need 2 of the 3 pieces to restore the full seed.
For me personally, this is the best tradeoff between security and convenience.
(I don’t think cryptosteel truly has much benefit over paper. It’s quite unlikely that a fire would destroy not just the seed but also both my devices in different locations at the same time.)
