+## Crypto Wallets
+
+The most secure medium to store your currency is cold (offline) wallets, since they cannot be hacked. Of course it is vital that you keep your private keys somewhere that they cannot be stolen, and cannot be lost or destroyed. Electronic devices can make it easy to securely store and spend crypto currency. Choose a wallet that is open source, and with a good reputation. Ensure you backup your seed, and keep it somewhere safe.
