Digital money is defined as any means of payment that exists purely in electronic form rather than physical form like cash. It is accounted for and transferred using computers rather than tangible currency. Examples of digital money include payments made using smartphones, credit cards, and online transactions over the internet. Previously, various commodities like beaver pelts, dried corn, and gold served as forms of money because they had intrinsic value and were durable. However, bartering direct trades of goods for other goods was inefficient since the goods you had may not exactly match what others needed. To address these issues, commodity money and then government-issued fiat currency were developed.
