What is a public address?

An address is an identifier of 27-34 alphanumeric characters that represents a destination for a Crypto payment. It is similar to email, in that you can send Crypto to a person or company using their address. You can have as many different addresses as you like (and it is recommended to regularly change addresses for security reasons), Blockchain Wallet does this for you every time you receive Crypto. However each previous address still points to your wallet.
