A #Bitcoin backup plate can help secure your seed words today...
And might just stop a bullet tomorrow. 😉
When considering the different types of #Bitcoin backup devices, it is best to choose a single solid piece of metal, ideally corrosion resistant, like 316L (marine-grade) stainless steel.
"Simpler is better - more pieces means more potential points of failure." - Jameson Lopp
The most important job of #Bitcoin seed storage plates, is to PRESERVE your private key.
Using a mechanical locking device to hide a private key is dangerous because it gives a false sense of security.
Solution = 2FA
Stored in two separate places.
SEED + PASSPHRASE
or MULTISIG
My knee-jerk reaction was to close all sales to the US market, but then realised that I just need take the hit until I can sort something more permanent.
Is your #Bitcoin backup fireproof 🔥, waterproof 🌊, chemical resistant 🧪, brick proof 🧱, sledge hammer proof ⚒️, and shotgun proof 💥?
If not, why not back it up on some solid pieces of marine-grade stainless steel (stored in separate locations). 👍
I don't recommend leaving your seed words on your signing device because it then relies upon a strong enough passphrase.
The key fob in this photo is like a one word passphrase. 😬
Once you protect your #Bitcoin with two-factor security (seed words + passphrase), you'll want to split everything of value into two required parts. 😉
Great question... It doesn't have to be BIP39 words as you said, but...
1. It's easier to actually measure the level of complexity/security with a known amount of possible combinations.
2. If they are ever discovered, then they don't look like a passphrase, and could be mistaken for part of a seed phrase or something else.

It's interesting to see how this real-world experiment compares with our theoretical calculations...
It's so important to understand how secure your #Bitcoin wallet's (2nd factor security) passphrase is.
When created by stringing together...
3x random BIP39 words = 33-bit secure
(est.d to take 8 seconds to hack with a supercluster of ASIC computers)
4x random BIP39 words = 44-bit secure
(est.d to take 4 hours to hack with a supercluster of ASIC computers)
5x random BIP39 words = 55-bit secure
(est.d to take 1.5 years to hack with a supercluster of ASIC computers)
6x random BIP39 words = 66-bit secure
(est.d to take 2,000 years to hack with a supercluster of ASIC computers)

Marine-grade @BitPLATES Domino plates are made from 316L stainless steel, not just 304 stainless steel, so #Bitcoin seed words and passphrases stay protected even against some of the Earth's most corrosive environments. 🌊
I know how you feel... I've just heard about it this morning, after spending hours trying to figure out why I'm being charged £85 to send a £120 product to the US. Small businesses are being eradicated one way or another. 😡
They come with soft foam protectors, but I would recommend a more inconspicuous cover. eg. DVD/Blue ray case.
We also provide security strips to check if your storage case is ever opened.

Preserve your #Bitcoin private key (seed words, passphrase, and multisig parts) on metal.
3mm solid plate with deep engraved alphabet and grid guide, made from 316L (marine-grade) stainless steel.
Always store seed words, passphrases, and multisig parts in separate locations.
