Cryptocurrency Glossary: The Language Of DeFi

In Summary:

  • The crypto market carries its own unique, ever-expanding terminology

Somewhere between cutting-edge financial technology, decentralized monetary systems, and internet meme culture, you arrive at cryptocurrency. From this fusion of technology and populism, digital currencies carry their own language that seems alien to even the most experienced traders of traditional assets.  

We’ve compiled a straightforward crypto glossary to help you decode some of the most common crypto terminologies. Of course, this list is by no means exhaustive because the industry is changing all the time, but that’s part of the appeal of this asset class.
