What users say about Coldcard Mk3
Real experiences from our community of users who have tried Coldcard Mk3 and its alternatives.
The Coldcard Mk3 is a game-changer for Bitcoin security. Its air-gapped nature and micro SD card integration for transaction signing provide peace of mind. The duress PIN feature and bricking passphrase are top-notch security measures. I especially appreciate the comprehensive documentation and open-source firmware. A must-have for serious Bitcoin holders.
Setting up the Coldcard Mk3 was straightforward, even for someone like me who isn't super technical. I really like the fact that it's air-gapped and I can verify transactions using the screen on the device. The build quality is excellent and feels very durable. I'd recommend it to anyone looking for a secure way to store their Bitcoin.
The Coldcard Mk3 is secure, no doubt. But the initial setup was a bit more complex than I expected. I found the menu navigation to be slightly unintuitive at first, but after watching some tutorials, I got the hang of it. The air-gapped operation is fantastic, and the price reflects the high level of security offered. Not the smoothest user experience, but extremely secure.
I have used several hardware wallets, and the Coldcard Mk3 stands out for its focus on Bitcoin and security. The PIN entry process is innovative and feels very safe. I also appreciate the fact that the device is tamper-evident. It's a bit more expensive than other wallets, but the peace of mind it provides is well worth the investment. The fact that it's Bitcoin only is a plus for me.
