A crypto address is a string of characters that identifies a wallet capable of sending and receiving bitcoin. It’s similar to a physical address, email address, or website. Every address is unique and identifies a wallet’s position on the blockchain.
The majority of blockchain addresses are difficult to understand since they are lengthy random strings of letters and digits.
Blockchain addresses are public, and you may view transactions in and out of them using a blockchain explorer. You may also view how much money the address has in its bank account. The privacy-based blockchains are the lone exception (eg. Monero and Grin).
