A #Bitcoin cold wallet is a method of storing Bitcoin offline, which makes it less vulnerable to hacking or theft. A cold wallet, also known as a hardware wallet, is a physical device that stores your private keys, which are needed to access your Bitcoin funds. The device is not connected to the internet, which eliminates the risk of online hacking or viruses. You can transfer Bitcoins to your cold wallet address from a hot wallet or exchange, but you need to physically connect the device to a computer or mobile device to perform the transaction. A popular cold wallet is a Ledger Nano S, which provides a higher level of security compared to hot wallets or online exchanges.
