The main difference between Coins and Tokens is in their structure; Coins are separate currencies with their own separate blockchain, while Tokens operate on top of a blockchain that facilitates the creation of decentralized applications. Coins are just method of payment while tokens may present a company’s share, give access to product or service and perform many other functions. Coins are currencies that can be used for buying and selling things. You can buy a token with a coin, but not vice versa. Coin operates independently, while token has a specific use in the project’s ecosystem.
