Coin operations are the basic activities and processes related to digital coins (cryptocurrency). They include creating new coins (mining), verifying and recording transactions (using consensus mechanisms like Proof of Work or Proof of Stake), and facilitating trades between buyers and sellers on exchanges. Miners and validators play a key role in making sure every transaction is secure and added to the blockchain. Coin operations also cover storage in wallets, the buying and selling of coins, and their use in payments or investments. These operations keep the network running smoothly, making cryptocurrencies secure, trustworthy, and available to users globally.
