"The public key (commonly shortened to pubkey) is known as the wallet's receiving address or simply its address. The wallet address may be shared and displayed freely. When another party is going to send some amount of cryptocurrency to a wallet, they need to know the wallet's receiving address. Depending on a blockchain's implementation, the address can also be used to view certain information about a wallet, such as viewing the balance, but has no ability to change anything about the wallet or withdraw any tokens. The private key is required to digitally sign any transactions to send cryptocurrencies to another address or to make any changes to the wallet. The private key must never be shared. If someone gains access to the private key to a wallet, they can withdraw all the tokens it contains. If the private key for a wallet is lost, any tokens that have been sent to that wallet's address are permanently lost." - solana presentations

Comment: there are also disadvantages of sharing public address. If your real personal info is associated with crypto wallet addresses what you do is no longer anonymous
