A coin or token is a digital asset that represents value and can be used for various purposes within a specific ecosystem. Coins, like Bitcoin or Ethereum, typically operate on their own blockchain and can be used for transactions, investments, or as a store of value. Tokens, on the other hand, often exist on existing blockchains, such as Ethereum, and can represent assets, utilities, or rights within a particular application or platform. Both coins and tokens are part of the broader category of cryptocurrencies, which utilize blockchain technology to ensure security and transparency. Users can buy, sell, or trade these digital assets on various cryptocurrency exchanges, making them accessible to a wide audience.
