There are too many choices, how do I choose?
- Avoid using devices where the device manufacturer knows your private key. Such as Keyois Capsule, Cold Storage Coins, and Ballet Crypto. In some cases it’s possible to have a manufacturer create a BIP38 encrypted backup, which is safe.
- Simpler is better - more pieces means more potential points of failure.
- The best bang for your buck are the single plates with grids for center punched dots such as Bitplates, Blockplate, CodlKeys, Crypto Keys, Smallseed, or Steelwallet
- The most durable device I’ve tested is the Quadrat Register
