The core innovation is that the hardware wallet must be connected to your computer, phone, or tablet before bitcoins may be spent.
The two most popular and best Cryptocurrency hardware wallets are:
Cryptocurrency hardware wallets keep private keys separate from vulnerable, internet-connected devices.
Your all-important private keys are maintained in a secure offline environment on the hardware wallet, fully protected even should the device be plugged into a malware-infected computer.
As cryptocurrencies are digital, cyber-criminals could, potentially, target your computer’s “software wallet” and steal them by accessing your private keys.
Generating and storing private keys offline using a hardware wallet ensures that hackers have no way to reach your cryptocurrencies.
Hackers would have to steal the hardware wallet itself, but even then, it can be protected with a PIN code.
Don’t worry about your hardware wallet getting stolen, lost or damaged either; so long as you create a secret backup code, you can always retrieve your cryptocurrencies.
