What is Coin

Coins are digital cryptocurrencies that run autonomously on their own blockchain platforms, whereas tokens are cryptocurrencies that rely on other blockchains to run. Ethereum allows other companies to generate tokens on top of its platform using the ERC-20 protocol. Some forks, despite originating from an existing blockchain network, are considered coins after the fork because once launched they run on their own blockchain. They can proceed in running regardless of what goes down with the original platform.
