The Ledger Nano S is probably the cheapest Bitcoin hardware wallet out there with a display functionality. It’s only $69 on Amazon, which is significantly cheaper than both the Trezor and KeepKey bitcoin hardware wallets. However, does that mean there are compromises? Well, maybe.
The KeepKey is a small, sleek little box that can (mostly) fit in your pocket. The basic functionality is that you connect the device to your computer, load up a chrome extension, update the device, and you can start storing Bitcoin, Litecoin, Namecoin, Dogecoin, Dash, Testnet, and Ethereum (on the PC beta app).
