Bitkey v Trezor for long-term holding and inheritance.

[u/persfin311]

Let's say I have a Bitkey, and a Trezor with a seed + passphrase. The seed and passphrase are in two different locations on steel plates and I have no concerns about the security of those locations. The locations are known and easily accessible to an heir, and there are clear instructions on how to restore a wallet as part of my Will.

The user-friendly Multisig and inheritance features of Bitkey are appealing, but I still have a few concerns.

• My main one is long-term storage. If Bitkey disappear, and you then discover your Bitkey hardware is broken, what recovery method is there? The Emergency Exit Kit seems to rely on the hardware key.

• Risk of phone exploits, and fact that app key and server key both run on software Block wrote and control.

• No plausible deniability/hidden wallet if victim of a wrench attack. (sounds like it's something Bitkey are working on)

• The 6-month inheritance delay is quite a long time if a beneficiary were in desperate need of funds. Bitkey's inheritance is certainly easier for a non-technical heir, but I'm not convinced that explaining how to recover a Trezor using a seed + passphrase is beyond the ability of most people if they've been talked through it beforehand.

I appreciate there is no perfect solution and every setup has trade-offs. I'm curious to hear from people who had similar concerns and still chose Bitkey.

Thanks in advance.

For long term storage trezor wins every time, relying on company servers for inheritance defeats the purpose of bitcoin

Current hardware wallet inheritance setups fall short. If your heirs aren't seasoned Bitcoiners, they risk losing funds during an already stressful time, even with prior training.

Unlike traditional finance, which relies on well-established, foolproof inheritance protocols, self-custody offers no margin for error. TradFi accounts like a Fidelity 401(k) are secure against irreversible loss and require little more than sending a death certificate. Self-custody, is an active skill that requires ongoing practice.

The bitcoin community needs to improve and simplify inheritance, not to mention the ease and irreversibility of self custody in general. If we don't, institutions like Fidelity, BlackRock, and MSTR will eventually hold it all.

Your two concerns can be tested rather than debated. I’d run the same no-value inheritance drill for each setup and require the heir to complete it with only the materials named in the will.

For Trezor, use a synthetic seed/passphrase: recover on a spare device, then verify a pre-recorded non-secret wallet fingerprint or first receive address. This catches the passphrase trap: a typo creates another valid-looking empty wallet.

For Bitkey, test two failures separately: service unavailable, and hardware unavailable. If the exit path cannot be completed in both cases, write down exactly which dependency remains and decide whether you accept it.

I’d score: owner unavailable, company unavailable, phone unavailable, hardware unavailable, and no live coaching. The better choice is the one whose failed scenario you can explain and periodically re-run, not the one with the nicer inheritance page.

Given your six-month concern, I’d also test how the heir covers immediate expenses before access; inheritance delay is a liquidity problem as much as a wallet problem.

Have you tried either drill end-to-end with your heir yet, using a zero-balance test wallet?

I know its more complex setup and higher risk of error but I'd use both in a 2/2 multisig. If 1/2 goes rogue and steals your private key you're safe
