Coin in more detail
A coin is the built-in currency of its own blockchain. A token is created by a smart contract on a blockchain that already exists. The difference affects fees, risks and several common mistakes.
Bitcoin is the coin of the Bitcoin blockchain. Ether is the coin of Ethereum.
ERC-20 tokens are fungible: every unit is identical to every other, like coins of the same value. A second standard, ERC-721, covers non-fungible tokens, or NFTs. Each NFT is unique, which suits tickets, collectibles and certificates.
