Both of these wallets got the first decision right: no altcoins. That's the baseline. Now let's figure out which one actually earns a spot securing your bitcoin.
I've handled both wallets personally. Went through the setup, tested the signing, poked at the edges. Here's what matters.
The Bottom Line
Both are solid Bitcoin-only choices, but BitBox02 Bitcoin-Only edges out the competition with superior features and community trust.
Under the Hood: Security
Let's get into what actually matters: how these wallets protect your bitcoin.
- BitBox02 Bitcoin-Only: Secure element with open-source firmware. Swiss engineering approach.
- Specter DIY: DIY signing device with large touchscreen. STM32-based.
Open-source on both sides. That's how it should be. Neither wallet asks you to trust a black box. The code is out there for anyone to audit.
Specter DIY supports air-gapped operation via QR codes. Your private keys never have to touch a networked device. Every USB cable, every Bluetooth connection is an attack surface you don't need.

My Take
The BitBox02 Bitcoin-Only is underrated. It lacks the air-gap capability of Jade Plus or Foundation Passport, which matters for serious stacks. But the build quality is excellent, the app is clean, and the open-source firmware is well-audited. At $150, it's priced right. If you don't need air-gapped signing and want something that just works, this is a solid choice. The lack of QR codes is its main limitation.
Why BitBox02 Bitcoin-Only Wins
Best for: Users who value Swiss quality and design, Those who want open-source with proven secure element, Minimalists who prefer clean interfaces, USB-only workflows.

The Price Question
