Absolutely yes. While the COLDCARD Mk4 might look like a basic calculator, it’s packed to the gills with security that few hardware wallets can compete with. Their use of not just one secure element chip, but two also allows them to have top tier level security that ensures your bitcoin is safe and sound in cold storage.

From the numerous physical security measures to stop physical tampering to their extremely refined software, it all ensures this bitcoin only hardware wallet will keep your life savings safe for years. That being said there are still a few things we think Coinkite can focus on for their Mk5 (or Q1?) version.

This includes things like better build quality or quality controls, slightly easier to press and more reliable physical buttons and ensuring all font is big enough to be easily legible in all parts of the software.

While the price of the COLDCARD Mk4 isn’t as cheap as some other wallets out there, it’s clear that this is a bitcoin wallet that means business and will grow with you, no matter how paranoid you become.
