A coin is a cryptocurrency that runs on its own independent blockchain. Unlike tokens, which are built on existing blockchains, coins act as the native currency of their networks and are mainly used as a medium of exchange or store of value.

For example, Bitcoin (BTC) operates on the Bitcoin blockchain, while Ether (ETH) is the coin of the Ethereum network. Each coin is recorded on its blockchain through a decentralized ledger that verifies and secures every transaction.

Coins can be traded on crypto exchanges, swapped through atomic swaps, or transferred via peer-to-peer (P2P) transactions. Their value depends on market demand, supply, and overall adoption.

While tokens are often created through Initial Coin Offerings (ICOs) on platforms like Ethereum, coins represent the foundation of a blockchain’s economy and are essential to its operation.
