Although more and more people are becoming aware of cryptocurrencies, much of the language used can seem a bit daunting and peculiar. Unlike conventional money, the ever-growing space of crypto requires some understanding of somewhat complex concepts.
It’s beneficial first to understand that a cryptocurrency is a digital currency facilitated through cryptographic means. For instance, does the term ‘mining’ have any relation to precious metals being dug out of the ground?
What about blockchain? Luckily, this article has put together a relatively comprehensive A-Z glossary of the phrases any new or experienced enthusiast in cryptocurrencies will likely come across in their journey.
