There were many attempts to create a digital currency during the technology boom of the 1990s, with systems like Flooz, Beenz, and DigiCash appearing in the market but ultimately failing. There were many reasons for their failure, such as fraud, financial issues, and even friction between company employees and their bosses.
It is worth noting that all of these systems used a trusted third-party approach, meaning that the companies behind them validated and facilitated transactions. Due to the failures of these companies, creating a digital currency system was seen as a hopeless case for a long time.

Cryptocurrencies are virtual or digital currencies designed to function as a medium of exchange. They use encryption to secure and verify transactions as well as to control the creation of new units of any specific digital currency. Essentially, cryptocurrencies are limited entries in a database that can only be altered if certain conditions are met.
