Digital Currencies Explained

Digital currencies are money-like assets that exist only in digital form, exchanged digitally, and are not controlled by central banks or governments.

While the syllabus might define digital currency as purely electronic, a broader definition includes any currency recorded and transferred on computers (e.g., online bank accounts for pounds, euros, dollars). Traditional currencies can exist digitally. Cryptocurrencies, however, are purely virtual with no physical version. All cryptocurrencies are digital currencies, but not all digital currencies are cryptocurrencies.

Digital currencies have been an accepted form of payment, allowing transfers between accounts without physical cash, enabled by online banking and smartphone payment apps. These traditional digital currencies, while existing as data, can be converted into physical cash.

There are thousands of cryptocurrencies, with Bitcoin being the most well-known. More businesses and even nations are accepting cryptocurrencies as payment.

Digital currencies (traditional) rely on a central banking system, which brings limitations in maintaining confidentiality and security. Cryptocurrencies, in contrast, bypass centralized banking and government authority, using cryptography to track publicly available and secure transactions through a blockchain network.
