The physical private key: titanium plate signing system
Bitcoin promises ownership but the key always lives in a chip you can’t see or touch. Frozen Security replaces that chip with a titanium plate — your private key encoded as a pattern of holes in metal. A signing terminal reads the plate, signs the transaction in volatile memory, and clears everything immediately. No digital key stored anywhere, ever. The first time your Bitcoin is something you can actually hold.

Windows installers can't find internal HDD on my 2000 Toshiba laptop. Tried both XP and 10 installers. Linux has no problem with finding and installing. It's not that it doesn't see partitions, it doesn't see the device at all. Help pls :/
