Her face when you show her your girthy 4 inches from Keystone. Yes, it is about screen size — the Keystone 3 Pro packs a full 4-inch touchscreen display, making it one of the largest screens on any hardware wallet. And that size matters more than you might think for Bitcoin security.
Why Screen Size Matters for Security
A screen is not just a fancy way to use your Bitcoin wallet — it is essential so you can clearly see what you are signing and verify the address you are sending sats to. There are real hacks that can change what you see on your computer screen, but they do not work on a dedicated hardware wallet. The Keystone large 4-inch touchscreen gives you a clear, uncompromised view of every transaction detail, adding protection that smaller-screen wallets cannot match.
