Virtual currency is a type of digital money that exists only in electronic form. Unlike traditional currencies, such as the US Dollar or Euro, virtual currencies are not issued or regulated by any central authority. They can be used for online transactions, trading, and sometimes even for purchasing goods and services in the real world. One of the most well-known examples of virtual currency is Bitcoin, which was created in 2009. Virtual currencies often rely on technology called blockchain to ensure secure and transparent transactions. Users can store, send, and receive virtual currencies using digital wallets, making them accessible and convenient for online use.
