As with any technical area of interest, you will often encounter many jargon words and technical concepts. Below we will list important cryptocurrency terminology you’ll often read in crypto circles. This will help you keep tabs on the most prominent concepts and words when navigating this field. For ease of reference, the terms are laid out in alphabetical order. 


This refers to the sender or recipient’s “wallet”. It’s essentially a sequence of letters and numbers representing the destination for you to send and receive cryptocurrency. Each address is specific to every network (for example, a Bitcoin address for a Bitcoin account). 

Altcoin (Alt)

These are all other cryptocurrencies that aren’t Bitcoin. Following its success, altcoins were developed to improve on Bitcoin’s perceived failures and act as alternatives. 

All-Time High (ATH)

The highest price a particular currency has reached. 


In cryptocurrency terminology, arbitrage is when traders take advantage of price differences between different exchanges. Even modest differences can reap the rewards. 

Bear Market

A crypto market that either stagnates or trends downward. 


The first decentralised cryptocurrency allows for peer-to-peer financial transactions based on blockchain technology.   


A grouping of transactions all confirmed (verified) and put together before being tagged onto a blockchain


A distributed and digitalised public ledger. This is where most cryptocurrencies’ transactions and balances are recorded as sequentialised blocks of verified transactions protected by cryptographical hashes. These transactions are immutable. 


In cryptocurrency terminology, trading bots are programmed software which allows the execution of trades on market exchanges without the supervision of a person or entity. 

Bull Market

The opposite of a bear market: this is when prices trend upward. 

Buy Low, Sell High

A typical mantra, it’s good to buy low and sell high (and avoid the opposite). 


In cryptocurrency terminology, this is a digital currency used in the crypto ecosystem. It represents one unit of the particular currency. While the term coin is often used interchangeably with the term token, some currencies specifically use the term token as opposed to coins (such as Ethereum’s Ether token). 


A currency used as a medium of exchange relies on cryptographic technology. 


The technology behind the secure encoding and decoding of cryptocurrencies. It’s more fundamental to crypto than the currencies themselves. 

Cryptographic Keys

Public-private key cryptography is the norm in exchanges. The public key is a publicly known address where cryptocurrencies can be received. The private key is known only to the owner of the public address and is used by the owner to access their currency. Both public and private keys are information represented as unique strings of numbers and letters.   


Exponential Moving Average (EMA)

A line that assists traders in tracking trends that incorporates price behaviour over time. 


In cryptocurrency terminology, this refers to a change in a cryptocurrency’s protocols. The developers of a currency can update its protocol now and then, thus “splitting” the software. This results in both hard and soft forks. Hard forks create two separate but identical versions of the previous software but are now treated as separate blockchains that change over time. Soft forks are simply updates to the underlying software, usually on the software that operates on the blockchain. 

Fundamental Analysis (FA)

In cryptocurrency terminology, it refers to researching and evaluating a currency’s intrinsic value. This is done by complementing price movement data from technical analysis graphs with external factors. Anything that could meaningfully influence the price of the currency in question, such as news or information on its creators, is analysed. 

Going Long

If a trader is “going long” (or “taking a long position”), it means that they are betting a currency price will soon increase in value. 


This is a line of characters that represents a particular cryptographic key. Hash algorithms generate these to incorporate data into these hashes. Any modification to the hash changes the data, and vice versa. 


Unique to cryptocurrency terminology, this is an acronym that many in the crypto world take to mean “Hold On for Dear Life”. It was a meme that was spread through a misspelling of the word “hold” on an old forum post. You will HODL if you want to come out the other side of a fluctuation in the market, holding onto your currency.  

Initial Coin Offering (ICO)

This is the process of raising money to distribute a new token popularised by Ethereum. Tokens are offered in return for investment. 

Market Orders

Transactions are done as quickly as possible at the current market price. 

Market Price

The general price of a currency at a given time. 


In cryptocurrency terminology, this is solving cryptographic puzzles with software to confirm transactions and then add them to the public ledger. Miners get rewarded with coins for performing this action. 


A word unique to cryptocurrency terminology is when the price of a particular currency increases quickly. The joke is that the price goes through the stratosphere to the moon. 


Any server or computer hosting the distributed blockchain. These distributed nodes maintain the integrity of the public ledger. 

Panic Selling

This is pretty much what it says – selling in a panic when the currency prices are low and seem to be going further down. It is an example of how emotions can affect the market. 


Proof-Of-Work (PoW)

The investment of time and power to perform crypto mining. It’s seen as the proof needed to show that work has been done, after which this is exchanged for coins. 

Pump And Dump (PND)

The coordinated effort to pump coins into the market to raise their value artificially inflates the price. This is why sudden growth in cryptocurrencies must sometimes be treated with scepticism before buying into the sudden rush. Some PND tactics do increase the value of a coin over time. However, they typically cause instability in the market. 

Return On Investment (ROI)

The efficiency of your investment in the crypto market, usually in the form of an increase in profit. 

Relative Strength Index (RSI)

An indication of the oscillations in the market over time. It’s used to track price gains and losses data over a period to glean price fluctuations’ pace and movement. 


If you “short”, you would bet that a particular currency’s value price will fall or depreciate soon. Shorting can result in large profits but is extremely risky due to the volatile nature of the market.    

Smart Contract

In cryptocurrency terminology, this is a contract in the form of software. It has the same functions as a regular digital contract, but now with the added functionality of the decentralised blockchain system. 


The difference between the highest and lowest bid on a cryptocurrency. 

Stop-Loss Order

This is the limit set for when a particular price is reached to prevent further losses on a currency. It limits any potential losses to a predetermined and acceptable range. 

Technical Analysis (TA)

This form of analysis is different from fundamental analysis. In cryptocurrency terminology, technical analysis is the scientific activity of future trend prediction in cryptocurrencies. A currency’s past data (typically price and volume) are used to ascertain future price movements. It’s the go-to for cryptocurrency speculation but should be complemented with fundamental analysis and others to ensure predictions are as strong as possible. 


In cryptocurrency terminology, this is a digital currency used in the crypto ecosystem. It represents one unit of the particular currency. The word token can be used interchangeably with coins, but not always (such as Ethereum’s Ether token). 


Information in cryptocurrency networks is tokenised. This means they are encrypted and altered into data strings, which can then be stored on the distributed blockchain. Tokenisation is this very act of encryption and alteration into data strings. 


For crypto to exchange “hands”, data is added to the existing blockchain to represent this exchange. This process is known as a transaction. 

Transaction ID

This unique number is ascribed to each transaction to allow easy tracking. 


These are investors in cryptocurrency with large capital behind them. They usually have many coins or tokens and can influence the market considerably. The joke goes that whales “make waves” in the market. 

White Paper

When cryptocurrencies are created, their developers often provide white papers. These documents provide information about the currency and detail the technology supporting it. When contemplating an ICO, white papers are often essential reading before making a decision. 


Having a handle on cryptocurrency terminology while navigating the marketplace can only help ensure proper investments are made. Terminology can change so potential traders can benefit from sufficient research and the latest information. In light of this, our glossary and terminology list should help you stay informed.
