Why Coldbit Steel?
Bitcoin is a remarkable form of decentralized, censorship resistant, sound money. But to reap its benefits people need to properly manage their keys.
Coldbit offers tools and guides that explain how to do proper key management in Bitcoin without relying on third parties (self custody).
Coldbit offers physical, easy to understand security for your Bitcoin keys.
Cold Steel - Physical Security
Stamping steel is the best way to preserve extremely valuable information like your Bitcoin seed.
It may not be as easy as printing a sheet of paper or encrypting a USB drive but it offers unparalleled durability and longevity to those who can do it.
Coldbit means thick, stainless steel plates and hex rods, letter and number stamps made from hardened steel and heavy club hammers rather than vulnerable electronic devices, pieces of paper and trusted third parties.
- Better grip/control of the stamping bit (always in straight upright position, no wobble)
- Prevents the bit from flying across the room and as a consequence protects your eyes
- Protects your fingers
- Enables multiple punches in the exact same spot for deeper marks
- Easy control of the space between letters. The previously stamped letter is visible from the top and from bottom-right
