Normal Currency vs Cryptocurrency (Grade 11 NSC Matric Computer Application Technology): Revision Notes

Normal Currency vs Cryptocurrency

In recent years, digital currencies like Bitcoin and Ethereum have become incredibly popular and caught the attention of people worldwide. But what exactly makes cryptocurrency different from the regular money we use every day?

What is cryptocurrency?

Cryptocurrency can be understood as a form of digital money that exists only in electronic form. Unlike the cash in your wallet or the money in your bank account, you cannot hold cryptocurrency in your hands because it has no physical form whatsoever.

Here's how it works: when people buy and sell cryptocurrency, a special security system called cryptography protects their transactions. This system takes personal information about the buyers and sellers and scrambles it into a secret code that cannot be read unless someone has the right key to decode it. This makes cryptocurrency transactions very secure.

What is normal currency?

Normal currency, also called fiat currency, is the traditional money we're all familiar with - like South African rands, US dollars, or British pounds. This type of money has several important characteristics that make it different from cryptocurrency.

Firstly, normal currency is usually supported by something physical that gives it real value, such as gold reserves. It's created, controlled and backed by a country's central authority - in South Africa, this would be the Reserve Bank working with the government.

Normal currency is considered "legal tender," which means businesses and individuals are legally required to accept it as payment for goods and services. It also has an official value that can be tracked on world stock markets.

Key differences between the two types of currency

Centralisation vs decentralisation

Normal currency is centralised, meaning it's controlled by a single country's government and central bank. Cryptocurrency, however, is decentralised - no single authority controls it, making it global and independent of any particular country's economic policies.

Physical backing

Traditional money is typically backed by physical assets like gold or the economic strength of a country. Cryptocurrencies, on the other hand, are not tied to any physical items or single country's economy. Their value comes from supply and demand in the digital marketplace.

Limited supply

One interesting feature of cryptocurrencies is that they are finite - there's only a limited amount that can ever be created. This is very different from normal currency, where governments can print more money when needed.

The story of Bitcoin

Bitcoin provides a fascinating example of how cryptocurrency has evolved. When Bitcoin was first created in 2008, hardly anyone knew about it or understood what it was. For several years, it remained something that only computer enthusiasts were interested in.

However, as more people learned about Bitcoin, its value began to increase dramatically.

This example shows how volatile and unpredictable cryptocurrency values can be compared to traditional currencies.
