Cryptocurrency and digital currency are often used interchangeably, but they actually refer to different things. Digital currency is any currency that exists entirely in digital form, whether it's backed by a government or not. Cryptocurrency, on the other hand, is a type of digital currency that uses cryptography to secure and verify transactions, as well as to control the creation of new units.
While digital currencies like digital versions of the US dollar or euro are backed by a central authority, cryptocurrencies like Bitcoin or Ethereum are decentralized and operate independently of any government or financial institution.
