Cryptocurrencies are digital assets that use cryptography to secure and verify transactions, while digital assets can refer to any type of asset stored and maintained on a digital platform. Cryptocurrencies are typically decentralized and rely on peer-to-peer networks, while digital assets may or may not be held on a blockchain or other distributed ledger technology. Additionally, cryptocurrencies are typically used as a medium of exchange, while digital assets may have other functions such as representing other forms of value, property, or services.
