Hardware wallets are one of the best ways to securely store cryptocurrency without losing basic functionality. Wallets like the Ledger Nano S or Trezor boast security that would allow the device to be plugged into virtually any system without risking compromising a user’s private keys or other sensitive information — which could result in stolen funds. Private keys are stored on the device itself, so it is not necessary to put your trust into the security of a personal computer. In the case of physical theft, a pin or another method of user-chosen security is often required to access the device. This slows down the thief while you grab your replacement hardware wallet, enter your seed, and transfer the money out of your restored wallet.
