Using a hardware wallet – sometimes called “cold storage” – is widely accepted as the most secure method for storing cryptocurrency. It's backed by security experts and keeps your private keys offline – so your crypto is inaccessible to anyone but the holder of specific access codes.
A Hardware Wallet May Be the Safest Option\n\n Popular options from companies like Ledger, Trezor and SafePal also let you authorize transactions from the physical device. While you need to connect your device to a phone or computer and the internet to trade crypto, the private key never gets sent over the connection.
