What is Cold storage?
Cold storage or cold crypto storage is an offline method for storing cryptocurrencies and tokens. Cold storage implies that the digital assets are stored on a platform or wallet with no internet connection. Cold storing of digital assets means that the private keys will be located in an offline environment. It is considered safer than hot storage, and it is executed with cold wallets, which can be physical devices such as Ledger Nano wallets or Trezor wallets.
