Core crypto terms

Each term includes a simple definition, why it matters, and a risk note where useful.

Bitcoin

The first widely used cryptocurrency and a decentralized digital asset secured by a blockchain.

Why it matters

Bitcoin is often used as a reference point for the broader crypto market.

Risk note

Its price can still be volatile, and ownership requires careful wallet security.

Open term page

Ethereum

A blockchain network that supports smart contracts, tokens, decentralized apps, and NFTs.

Why it matters

Many crypto projects are built on Ethereum or use Ethereum-style token standards.

Risk note

Users should understand gas fees, contract permissions, and wallet approvals.

Open term page

Blockchain

A shared digital ledger that records transactions across many computers.

Why it matters

Blockchains make transaction history easier to verify than a private database.

Risk note

A public ledger does not mean every project using it is trustworthy.

Open term page

Smart Contract

Code deployed to a blockchain that can execute rules for tokens, apps, or transfers.

Why it matters

Token behavior can depend on smart contract code and owner permissions.

Risk note

Bad or malicious contract code can block sells, change fees, or expose funds.

Open term page

Wallet

Software or hardware used to manage crypto addresses and sign transactions.

Why it matters

A wallet is how users interact with tokens, exchanges, and decentralized apps.

Risk note

If a wallet or seed phrase is compromised, assets can be lost permanently.

Open term page

Private Key

A secret cryptographic key that controls access to a crypto address.

Why it matters

Whoever controls the private key controls the assets at that address.

Risk note

Never share a private key. No legitimate support team needs it.

Open term page

Seed Phrase

A set of words that can restore access to a crypto wallet.

Why it matters

It is usually the backup for wallet ownership.

Risk note

Anyone with the seed phrase can drain the wallet.

Open term page

Liquidity

The amount of available funds that lets buyers and sellers trade a token.

Why it matters

Low liquidity can make a token hard to sell without major price impact.

Risk note

Unlocked or removable liquidity can be a rug-pull warning sign.

Open term page

Market Cap

A rough valuation calculated by multiplying token price by circulating supply.

Why it matters

It helps compare the size of different crypto assets.

Risk note

Market cap can mislead if supply data, liquidity, or trading volume is weak.

Open term page

Fully Diluted Valuation

A valuation estimate using the maximum possible token supply.

Why it matters

It shows how large a project could be valued if all tokens existed in circulation.

Risk note

Large locked or future supply can create selling pressure later.

Open term page

Rug Pull

A scam where project insiders remove liquidity, abandon the project, or exploit users.

Why it matters

Rug pulls are a major risk in new and low-liquidity tokens.

Risk note

Check liquidity locks, owner permissions, token distribution, and project history.

Open term page

Honeypot

A token or contract setup where users can buy but cannot sell normally.

Why it matters

It can trap buyers even while the chart appears active.

Risk note

Do not assume a token is sellable just because buying works.

Open term page

Tokenomics

The structure of a token's supply, distribution, incentives, fees, and utility.

Why it matters

Tokenomics can explain who holds supply and how incentives are aligned.

Risk note

Unclear tokenomics can hide insider concentration or future unlock risk.

Open term page

Airdrop

A distribution of tokens to users, often for community growth or protocol usage.

Why it matters

Airdrops can introduce users to new projects and networks.

Risk note

Fake airdrops often request wallet approvals or seed phrases.

Open term page

Staking

Locking or delegating crypto assets to support a network or earn rewards.

Why it matters

Staking is common in proof-of-stake networks and some token ecosystems.

Risk note

Rewards are not assured, and lockups or smart contracts can add risk.

Open term page

Gas Fee

A network fee paid to process blockchain transactions.

Why it matters

Gas affects the cost of swapping, sending, minting, or approving tokens.

Risk note

High fees can make small trades uneconomical.

Open term page

DEX

A decentralized exchange where users trade from their own wallets.

Why it matters

Many new tokens launch on DEX platforms before major exchanges.

Risk note

DEX trading can expose users to fake tokens, slippage, and malicious approvals.

Open term page

CEX

A centralized exchange that holds user accounts and facilitates trading.

Why it matters

CEX platforms can simplify onboarding and liquidity access.

Risk note

Users rely on the exchange's custody, security, and rules.

Open term page

LP Token

A token representing a share of liquidity provided to a trading pool.

Why it matters

LP tokens can indicate who controls pool liquidity.

Risk note

If insiders control removable LP tokens, liquidity may be pulled.

Open term page

Slippage

The difference between expected trade price and the final executed price.

Why it matters

Slippage rises when liquidity is low or price moves quickly.

Risk note

High slippage can lead to worse fills or expose users to predatory trading.
