The essence of wallet security is to prevent private keys from being leaked or stolen by hackers. In the anti-theft strategy, Keystore and mnemonic (or plaintext private key) have different emphasis:
a.Keystore is the encrypted private key, and its content is encrypted information. Adopting a backup strategy such as copying is not very scientific. It can be stored in your own USB drive and not stored online or in the cloud. Store the Keystore separately from the password so that even if the keystore is stolen by a hacker, it is hard for the other party to crack it.
b.When storing mnemonics, you need to be more cautious, because once the mnemonic is stolen by a third party, then the third party will directly acquire the ownership of your assets. It is recommended to copy it on a piece of paper and keep it in an absolutely safe place. When copying, it is necessary to pay attention to accuracy, and it is also necessary to pay attention to long-term preservation, so as to avoid problems such as dissipated handwriting and unclearness.
