Cryptocurrencies are the newest form of digital money and exist in a distributed form on decentralized blockchains around the world.
Token cryptocurrency iconTokens on the other hand represent an asset or utility . They are transferable goods and can represent coins, loyalty points, assets in a game, etc. They can even be redeemed for a service that an issuer will provide at a later date.

Therefore, the main difference between the two is in their structure and their purpose:

Structure
While cryptocurrencies such as Bitcoin or Litecoin always have their own blockchain, the tokens operate ‘on top of another blockchain. For example, the OmiseGO and EOS tokens operate on top of the Ethereum blockchain.

Purpose
While the purpose of cryptocurrencies is to be a unit of value or payment method (replacing, for example, the euro or the dollar), tokens can basically represent any asset that is fungible and negotiable, from merchandise or votes to loyalty points. , And even other cryptocurrencies!
Even so, in practice, the line that divides cryptocurrencies and tokens is not clear and sharp today. Both are used to transfer value and as a means of payment, similar to the way both dollars and stocks are used to reward people for their work.
