Things have changed dramatically since Bitcoin was first released in 2009. Digital assets are accepted globally and these days, it’s easier than ever to send, receive, and earn rewards on cryptocurrency. Just like other asset classes, digital currency comes with a language all its own. Spend just a little time learning this language, and you’ll enjoy greater insight into the way cryptocurrency works.
This industry’s terminology is complex, as cryptocurrency brings the worlds of finance and computer programming together. Many common terms related to cryptocurrency are acronyms, and unless you’re familiar with them, reading information about crypto can be intimidating. Still other terms are common words that you probably recognize from other sectors: Address, coin, flipping, and wallet are a few that come to mind. When applied to cryptocurrency, these words are conceptually similar but with nuanced meanings.
Some cryptocurrency terms are trading related. If you’re at all familiar with trading, you’ll find that words and phrases used to discuss stocks, bonds, and other common financial asset classes have similar or even the exact same meanings when applied to conversations about crypto. Exchange, fiat, and margin trading are a few examples.
Learning a new language comes with challenges. That’s where our cryptocurrency glossary comes in. With more than one hundred crypto terms to sink your teeth into, it’s designed to give you more than simple translations. Our A to Z list of common words, acronyms, and phrases associated with cryptocurrency offers links to dedicated pages for each term, providing you with a well-rounded introduction to the world of cryptocurrency.
When you navigate to a new page, you’ll receive a short definition of the cryptocurrency term in question, along with a longer explanation when applicable.
