A Bitcoin address is a unique identifier that allows you to receive Bitcoin payments. It is also sometimes referred to as a public key.
Each Bitcoin address is associated with a public key and a private key, which are mathematically linked together. The public key is used to create a Bitcoin address and the private key is used to sign transactions and provide proof that the owner of the address is the one initiating the transaction.
Bitcoin addresses can be easily generated and used to receive Bitcoin payments. They are usually displayed as a string of letters and numbers and can be shared publicly.
