An easy-breezy way to understand public and private keys of the crypto wallet is to relate them to our email account or any social media accounts. Public keys are like our email address or social media user names, whereas private keys are the authorizing passwords. The sender requires only the crypto wallet’s public keys to deposit crypto coins in your wallet. You need not share your private keys to receive cryptocurrencies. A person can authorize or steal your crypto assets only if the private keys are known. Hence, you must never have the practice of noting down the crypto wallet private keys anywhere over the internet.
Secure your private keys, just like you hold your debit or credit card PIN!
