What is the difference between digital money and cryptocurrencies?

Could you elaborate on the key distinctions between digital money and cryptocurrencies? Are they both simply forms of electronic payment? Or do they possess distinct characteristics and use cases? In what way is cryptocurrency differentiated by its decentralized nature? Do digital money options tend to rely more on traditional banking systems, while cryptos aim for financial autonomy? And what are some examples of how cryptocurrencies have revolutionized financial transactions in recent years? Clarifying these differences would help me gain a deeper understanding of the two concepts.
