Private Key and Address: The "Lifeline" Usage Regulations in the Cryptocurrency World
◦ The private key is the "universal key" to your wallet, a string of random characters; if lost, it cannot be retrieved, and if leaked, it will be stolen.
◦ The public key/address is your "digital account," which can be shared with others for receiving cryptocurrency payments.
◦ The mnemonic phrase is a backup for the private key; write it down on paper and keep it safe, do not store it on electronic devices $BTC
