Is Bitkey true self-custody?

Partially. You hold 2 of 3 keys, but Block holds the third. You can't spend without their app working. It's better than an exchange but less sovereign than single-key wallets.

What happens if Block shuts down?

You have 2 of 3 keys, enough to move your bitcoin. But you'd need technical knowledge to do it without their app. Block has published recovery documentation.

Is Bitkey good for beginners?

Yes, that's its purpose. The 2-of-3 setup means losing your phone or device isn't catastrophic. For people graduating from exchange custody, it's a good first step.

Bitkey vs Jade Plus: which should I buy?

Different use cases. Bitkey is simpler with built-in recovery. Jade Plus offers true air-gapped sovereignty. Bitcoiners prefer Jade Plus; beginners might prefer Bitkey.

Jack Dorsey's Block built Bitkey for the masses. It's Bitcoin-only, which earns points. But the 2-of-3 multisig setup means Block holds one of your keys. You can't spend without their app. For hardcore Bitcoiners, that's a compromise. For someone whose alternative is keeping coins on Coinbase, this is a major upgrade.

Block committed to Bitcoin when Jack Dorsey went all-in. Bitkey is Bitcoin-only by design, not as an afterthought. The entire product exists to onboard normies to self-custody. That mission aligns with Bitcoin values even if the execution involves trust tradeoffs.

The Verdict

Bitkey is training wheels for self-custody. The 2-of-3 multisig makes recovery idiot-proof, but it also means Block is involved in your transactions. If you understand and accept that tradeoff, it's a fine product for beginners or gifting to nocoiners. If you want true sovereignty, get a Jade Plus or Foundation Passport instead. Bitkey exists for people who would otherwise leave coins on exchanges.
