Public keys allow the user to send or receive cryptocurrency transactions. Public keys are usually an address, which a user can use to identify where they are sending or receiving crypto.
Public keys can be shared.
While anyone can send to a public address, a private key is used to prove that you are the owner of the wallet and “unlock” the assets in the wallet. On many wallets, a private key is a 12-24 word seed-phrase. This is the Key / full access to the wallet.
Private keys should be stored securely, as they grant access to your wallet and the assets inside the wallet.
Safety is important - do not click on suspicious links, do not connect your wallet to suspicious websites. Legitimate exchanges won’t ask for your seed phrase or any privacy information.
