For MyEtherWallet wallet, information such as Password (Password), Private Key and File Keystore / JSON are very important, you need to store very carefully if you do not want your assets to be lost. When using the MyEtherWallet wallet, you need to do the following to protect the wallet:

  • Password: With a password you can easily remember so that you can remember it in your mind, but I recommend putting it a little hard to remember, by including both lowercase letters + capital letters + numbers + special characters (@ # $ % ^ &) to prevent hackers from being able to hack, then copy and save it to a Notepad or Word file.
  • Private Key: This is a very long series of characters that is difficult for you to remember, so you can copy and save Notepad, Word files or write directly on paper and store them in your safe.
  • Keystore / JSON file: This is a soft file format that is not the same as the above 2 so can't be written on paper, you can choose how to store on USB, memory card.

If you are a regular user, you should save this information in a Notepad file and keep it on your personal computer for convenient use. And if you are a long-term investor who buys Ethereum and stores a few months to a few years, it can be stored on paper, private USB, ... and stored in a safe, so no one can log in to the Ethereum wallet on your MyEtherWallet. OK.
