In 1998, Chinese engineer Wei Dai first introduced the concept of “cryptocurrency.” Unlike conventional currency, digital currency only exists online. Users can exchange cryptocurrency online after purchasing tokens using “real” — i.e., traditional or fiat — currency. Cryptocurrency eliminates the need for a central controlling authority, such as a financial institution or government office, and instead creates a fast, easy and effective way for people around the world to exchange money.
About a decade after the idea of cryptocurrency was first described, an innovator using the pseudonym “Satoshi Nakamoto” revealed the concept behind Bitcoin. Today, Bitcoin (or BTC) is one of the most popular forms of cryptocurrency. While Bitcoin has eliminated the need for a central authority, it hasn’t removed the costs associated with the technology underpinning cryptocurrencies. Knowing how this technology works can help you better understand transaction fees — and how to minimize your costs when using cryptocurrencies.
