Use a private wallet - A safe way to keep your cryptocurrencies would be to use a private wallet, preferably a cold wallet. In such wallets, they can protect you against computer failures or thefts and prevent the loss of your cryptocurrencies.
Encrypt your wallet - Use a strong password (Do not store the password in electronic form if possible), encrypt your private keys and store your encrypted private keys in a safe location. Any document or file stored on your computer is vulnerable to theft, so encrypting your private keys is a good practice.
Back up your private key / wallet - There is no way to recover your lost private key for your wallet. Once lost, it is irrecoverable. We recommend storing your encrypted private key [which is required to open your wallet] in multiple devices in different locations.
Offline wallets - One of the safest places to store your cryptocurrencies are in an offline hardware wallet - it is basically a purpose-made USB-like device that secures your private key and is only accessible when plugged into your computer. A password or PIN is usually required to access this device. Without physically having the device and the password/PIN, an attacker cannot access your private keys.
