51 Cryptocurrency Glossary: Dictionary of Cryptocurrency and Bitcoin Terms

The cryptosphere is getting more crowded than ever. More and more people are joining the space every day with the hopes of making quick money.

However, in the process, they are bombarded with numerous terminologies and crypto jargons that make most of them feel out of the sink.

When I started, I felt the same. But trust me when I say that learning these new terms and jargons is worth every bit of the hassle. Needless to say, it might seem overwhelming at first, but you will get used to it with time. If you intend to stay in the game, it is very important that you understand the terms used in the cryptosphere.

Moreover, if you are not a quick learner and don’t like updating yourself, you are destined to get outdated very soon considering this space is growing at an astronomical pace.

Keeping all these factors in mind, I have compiled a list of cryptocurrency terms and Bitcoin terminologies that you need to know and understand for a successful outing in the crypto world.
