What Does Crypto Mean?
Before we jump into the jargon and other crypto terms, let’s get clear on the basics. Let’s start with what crypto really is.
The Definition of Crypto
Crypto is short for cryptocurrency—a digital form of money built on blockchain technology. Unlike traditional currencies like dollars, euro or pounds, crypto isn’t issued by a central bank. Instead, it’s decentralised, often open-source, and governed by code and consensus over the internet.
Think of it like this: crypto is money that lives online and isn’t controlled by banks.
Examples of cryptocurrencies include:
- Bitcoin (BTC)
- Ethereum (ETH)
- Ripple (XRP)
- Solana (SOL)
- Pi Network (PI)

Cryptocurrencies allow you to send, receive, store, and invest money without a traditional middleman like a bank.
Now that we’ve covered the basics, let’s dive into some language of crypto.
Crypto Terms You Need to Know
Here’s a breakdown of the most common crypto terms and their meanings, grouped by category to make things easier.
Core Cryptocurrency Terminology
Cryptocurrency – A digital currency using cryptography for security. It exists only online and operates independently of banks or governments.
Blockchain – A public digital ledger that records all cryptocurrency transactions. It’s secure, transparent, and unchangeable.
Crypto Token – A unit of value issued on an existing blockchain. Tokens can represent assets, utilities, or other forms of value.
Altcoin – Any cryptocurrency that isn’t Bitcoin. Examples include Ethereum, Litecoin, and Pi Network.
Fiat – Government-issued currency like the British pound (GBP), Euro (EUR), or US dollar (USD). Crypto is often traded against fiat.
Wallet – A digital app or device that stores your private keys and allows you to send and receive crypto. Crypto wallets can be hot (online) or cold (offline).
Seed Phrase – A series of 12–24 words that act as a backup for your crypto wallet. Lose this, and you could lose access forever.
Beginner Crypto Slang Explained
HODL – Long story short, what originally began as a typo of “hold,” by someone at the very beginning of crypto, it now means “Hold On for Dear Life.” A strategy where users buy crypto and hold it long-term regardless of market fluctuations.
FOMO (Fear of Missing Out) – The anxiety you feel when you see a crypto pumping and you want to buy in before it’s too late.
FUD (Fear, Uncertainty, Doubt) – Another acronym widely used in crypto. Negative news or rumours that cause panic selling. Sometimes used deliberately to manipulate the market.
Crypto Pump and Dump – When a group boosts the price of a coin through hype, only to sell it at a peak—causing a crash.
What is a Crypto Whale – A person or entity that holds a large amount of a particular cryptocurrency. Their moves can shift market prices.
Bagholder – Someone who holds a cryptocurrency after its value drops, often significantly.
Trading and Investment Crypto Jargon
Crypto Bull Market – A market where prices are rising and investor confidence is high.
Crypto Bear Market – A market where prices are falling and pessimism is widespread.
ATH (All-Time High) – The highest price ever reached by a crypto coin or token.
ATL (All-Time Low) – The lowest price a crypto asset has ever traded at.
Liquidity – How easily an asset can be bought or sold without affecting its price. Higher liquidity means easier trading.
Slippage – The difference between the expected price of a trade and the price at which it’s executed.
Market Cap – The total value of a cryptocurrency’s circulating supply. This is calculated by this formula: price x circulating supply.
Volume – The total amount of a crypto traded in a given period. High volume means high activity.
What Does HODL Mean?
This one’s classic crypto slang. “HODL” started as a typo in a Bitcoin forum back in 2013. Someone meant to say “hold” but wrote “HODL”—and it stuck. Today, HODL means: Hold onto your crypto for the long term, or Hold On for Dear Life – even during market dips.
HODLers believe in the future of crypto, ignoring short-term volatility. It’s both a mindset and a meme.
What Is Proof of Stake in Crypto?
You’ve probably heard this phrase thrown around—especially with Ethereum’s upgrade.
What Does Proof of Stake Mean?
Proof of Stake (PoS) is a consensus mechanism—a way for blockchains to agree on what’s valid.
In PoS:
- You stake (lock) your coins to support the network
- In return, you may earn rewards for helping validate transactions
It’s seen as:
- Energy-efficient
- Fast and scalable
- More sustainable than older models
What Is Proof of Work in Crypto?
Before PoS, there was Proof of Work—popularised by Bitcoin.
How PoW Works
Proof of Work (PoW) is the original way crypto networks validate transactions.
In PoW:
- Computers solve complex problems
- The first to solve it gets to add a new block
- They earn newly minted coins as a reward
While secure, PoW is:
- Energy intensive
- Slower than newer models
Bitcoin still uses Proof of Work and it’s partly why mining BTC requires specialised equipment.
What Does Pump and Dump Mean?
This is one of the dodgy sides of crypto and a term worth knowing to avoid scams.
Crypto Pump and Dump Explained
A pump and dump is a manipulation scheme where:
- A group hypes a coin (often with false claims)
- The price “pumps” as people rush to buy
- Organisers sell at the top (“dump”), crashing the price
Avoid coins with:
- Sudden hype
- No clear purpose
- Zero transparency
Tip: If it sounds too good to be true, it probably is.
Crypto Terms for Wallets
Crypto Private Key – A secret string of letters and numbers that gives you control over your crypto. Never share this.
Public Key – Your crypto receiving address. Safe to share with others.
Hot Wallet – A wallet connected to the internet, such as a browser extension or mobile app.
Cold Wallet – A wallet stored offline, like a hardware device or paper wallet. More secure for long-term storage.
2FA (Two-Factor Authentication) – An added security layer where a second device or app (like Google Authenticator) confirms your identity.
What Is a Crypto Private Key?
Crypto means you control your money. But with control comes responsibility—especially over your private key.
Crypto Private Key Explained
A private key is a unique code that gives access to your crypto. Think of it like a password to your bank account. Anyone who has it can move your coins.
You’ll see two types of keys:
- Public Key – like your crypto wallet address
- Private Key – what proves you own the coins
NEVER share your private key. If it’s lost or stolen, your crypto is gone for good.
What Is a Crypto Wallet Seed Phrase?
Closely tied to your private key is your seed phrase. This is your most precious code in crypto, if you lose this code your crypto wallet is gone. Keep this code in a place you can find it, but also keep it out of the hands of others. If someone gains access to your seed phrase, they have full control of your crypto wallet.
A Crypto Seed Phrase = Crypto Wallet Master Key
A seed phrase (also called a recovery phrase) is usually 12 or 24 words randomly generated when you create a crypto wallet.
It’s used to:
- Restore your wallet
- Recover your coins if you lose your phone or app
Make sure to write it down. Store it offline in a safe place and most importantly, keep your seed phrase private.
Example of a seed phrase:
slice hammer vacuum bullet swim egg nest fire echo coconut lava skate
Lose this and you lose access—forever. Need help getting started? Read: How to Create a Crypto Wallet
What Is a Crypto DApp?
A DApp is short for decentralised application. It looks like a normal app but runs on blockchain tech. Instead of relying on one central server, DApps run on peer-to-peer networks. They’re often open source.
Popular DApps:
- Uniswap – Trading
- OpenSea – NFTs
- PancakeSwap – DeFi
- Pi Network Apps – Community tools and projects
DApps are shaping the future of Web3 and blockchain. Make sure to keep up to date with new DApps, these could be the future of internet applications and it might be worth getting involved early.
What Does Market Cap Mean in Crypto?
Market cap isn’t just Wall Street talk, it’s also critical information in the crypto world too now.
What Is Crypto Market Cap?
In crypto, market cap stands for market capitalisation. It measures the total value of a cryptocurrency.
Crypto Market Cap Formula:
Market Cap = Coin Price × Circulating Supply
Example of a Crypto Market Cap: If 10 million coins are in circulation and each is worth $1, then market cap = $10 million.
Why it matters:
- High market cap = more established and stable
- Low market cap = riskier but can offer higher growth
So next time you wonder, “what does market cap mean in crypto?”, remember it shows the size and potential stability of a coin.
What’s an Altcoin in Crypto?
You’ve heard of Bitcoin. But what about the rest? These are altcoins. Altcoin simply means any cryptocurrency other than Bitcoin. Alt stands for alternative. So, altcoins are alternative coins to the top crypto coins on the market like Bitcoin.
Popular altcoins include:
- Ethereum (ETH) – Smart contract platform
- Pi Network (PI) – Free-to-mine mobile coin
- Solana (SOL) – Fast Layer 1 blockchain
Some altcoins are experimental, others have major utility. Either way, they make up the majority of the crypto market.
What Is Blockchain in Crypto Terms?
A term that pops up everywhere in crypto is blockchain and for good reason. This is the technology which all crypto operates on, this tech enables the decentralisation of crypto.
What is Blockchain Technology?
A blockchain is a digital ledger that records transactions in a way that’s:
- Permanent
- Tamper-proof
- Distributed across a network
Every time someone sends or receives crypto, that transaction is recorded on a “block.” These blocks form a chain—and that’s in short your blockchain. It’s the foundation of nearly all cryptocurrencies.
Blockchain and Tech-Driven Crypto Terms
Smart Contract – A self-executing agreement written in code on a blockchain. Used in DeFi and NFTs.
Crypto Gas Fees – The cost of completing a crypto transaction on the blockchain. These vary based on network congestion.
Proof of Work (PoW) – A consensus algorithm that requires solving complex problems to validate transactions. Used by Bitcoin.
Proof of Stake (PoS) – An alternative to PoW where validators are chosen based on how much crypto they hold and “stake.”
Crypto Nodes – A computer that maintains and validates the blockchain’s ledger. Essential to decentralisation.
Crypto Hash – The result of a cryptographic algorithm used to secure transactions. Hashes are vital for blockchain security.
Crypto Fork – A split in a blockchain that creates two versions of the network. These can be hard forks (major changes) or soft forks (minor upgrades).
Other Relatable Crypto Terms
What Is Web3 in Crypto?
Web3 is the next evolution of the internet—powered by blockchain.
In Web3, users own their data and digital assets. Instead of using platforms like Facebook or Google, you use decentralised applications (DApps) built on blockchains.
Key Web3 crypto terms include:
- DApp – Decentralised Application
- DAO – Decentralised Autonomous Organisation
- Metaverse – Digital worlds and economies where you can buy land, NFTs, and more
What Is DeFi in Crypto?
If you’ve been around the crypto space, you’ve seen “DeFi” everywhere. But what does it mean? DeFi stands for Decentralised Finance. It’s a new way to access financial services without banks or brokers.
Instead of using a bank to save money, take out a loan, earn interest or trade assets. You can do all that through smart contracts on blockchains like Ethereum.
Examples of DeFi platforms:
- Uniswap – Trade tokens
- Aave – Borrow/lend crypto
- Compound – Earn yield
Could DeFi be the future of global finance? It sure looks like a good option, we will have to wait and see.
Understanding DeFi (Decentralised Finance)
DeFi is short for Decentralised Finance, a system where financial services like lending, borrowing, and trading occur on blockchain networks rather than traditional banks. You don’t need banks. You interact directly with smart contracts.
Common DeFi Crypto terms:
Liquidity Pool – A smart contract holding tokens to facilitate decentralised trading.
Yield Farming – Earning rewards by providing liquidity to DeFi protocols.
Crypto Staking – Locking up your crypto to support network operations and earn rewards.
APR/APY – Annual interest rates you earn from staking or farming, expressed as a percentage.
What Does Fiat Mean?
In crypto, you’ll often hear things like “Convert your fiat to crypto” but what does fiat mean?
Understanding Fiat Currency Compared to Crypto
Fiat is government-issued currency like:
- British Pounds (£)
- US Dollars ($)
- Euros (€)
It’s not backed by a physical asset like gold. Instead, its value is based on trust in the government that issues it. Crypto was created as an alternative to fiat, aiming for more transparency, lower fees, and decentralisation away from governed money and traditional banks.
NFT Terminology (Non-Fungible Tokens)
NFTs are unique digital assets stored on a blockchain commonly used in art, gaming, and collectibles.
Popular NFT crypto terms:
Minting – The process of creating a new NFT on a blockchain.
Floor Price – The lowest price you can pay to purchase an NFT from a collection.
Rug Pull – A scam where NFT creators disappear after collecting investors’ funds.
Utility – Real-world benefits or functions attached to owning an NFT (like event access or digital perks).
Tax and Legal Crypto Terms
Capital Gains – Profits made when selling crypto at a higher price than you bought it. Taxable in the UK and many countries.
KYC (Know Your Customer) – Identity verification process required by exchanges for regulatory compliance.
AML (Anti-Money Laundering) – Laws designed to prevent illegal use of crypto and other financial systems.
Crypto Regulation – Government oversight of the crypto market. This is evolving rapidly, especially in the UK and Europe.
Why Learning Crypto Terms & Language Matters
Understanding the widely used crypto terms is essential whether you’re:
- New to crypto
- Learning how to invest
- Exploring decentralised apps
- Mining free crypto coins
- Joining a new crypto network like Pi (or similar apps)
It allows you to make informed decisions, avoid scams, and gain confidence. When you can read crypto charts, understand news reports, and navigate exchanges—you’re no longer guessing. You’re participating.
The Most Misunderstood Crypto Terms
Let’s clear up a few final crypto terms people often get wrong:
Crypto Coins vs. Crypto Tokens
A crypto coin is a native asset of its own blockchain (e.g. Bitcoin or Ethereum). A crypto token is built on top of another blockchain (e.g. USDT on Ethereum’s blockchain).
Decentralised Crypto
It doesn’t mean “no rules”—it means no single person or organisation controls the system. Everyone has access to the blockchain and transactions are confirmed by others on the network.
Crypto Stablecoins
A crypto asset pegged to a fiat currency like USD, GBP or EURO. Examples include USDT and USDC. The value of these coins reflect the value of the fiat currency ($1 in USD is 1 USDT).
