Digital cash refers to money that exists only in electronic form, allowing users to make transactions online without the need for physical currency. It can be used for various purposes, such as online shopping or transferring funds between individuals. Digital cash is often stored in digital wallets and can be accessed through computers or smartphones. One popular form of digital cash is cryptocurrency, which uses blockchain technology to secure transactions and control the creation of new units. Unlike traditional currencies issued by governments, digital cash operates independently and can provide users with greater privacy and lower transaction fees.
