Designed for beginners, this guide covers foundational concepts across trading, investing, blockchain technology, and market behavior. By the end, you’ll have a solid grasp of the language used in the crypto space—and the confidence to navigate it.
A
Arbitrage
Arbitrage is a trading strategy that capitalizes on price differences for the same cryptocurrency across different exchanges. Traders buy low on one platform and sell high on another, profiting from the gap.
All-Time High (ATH) / All-Time Low (ATL)
An asset’s ATH is the highest price it has ever reached, while the ATL is its lowest recorded price. These markers help traders assess market cycles and sentiment.
Bid Price
The bid price is the highest amount a buyer is willing to pay for a cryptocurrency at a given moment.
Average Directional Index (ADX)
ADX measures the strength of a market trend, regardless of direction. A high ADX value suggests a strong trend, while a low value indicates a sideways or consolidating market.
Accumulation/Distribution Line (A/D)
This indicator estimates supply and demand by combining price and volume. It’s cumulative—each period’s value builds on the previous one—helping traders identify potential reversals.
B
Ask Price
The ask price is the lowest price at which someone is willing to sell an asset.
Bull Market
A bull market refers to a period of rising prices and positive investor sentiment. It's characterized by optimism and increasing demand.
Bear Market
Opposite of a bull market, a bear market sees declining prices and widespread pessimism. Investor confidence drops, often leading to prolonged sell-offs.

Buy Order / Sell Order
A buy order is placed when a trader wants to purchase an asset at a specified price. A sell order is used to offload assets at a desired price.
BTFD (Buy The F*ing Dip)
BTFD is a slang term encouraging investors to buy assets immediately after a price drop. While it can lead to gains if the market rebounds, it’s risky without proper analysis.
BUIDL
A play on “HODL,” BUIDL emphasizes actively contributing to blockchain projects—through development, advocacy, or usage—rather than just holding assets.
C
Copy Trading
Copy trading allows users to automatically mirror the trades of experienced investors, often in futures or spot markets. It’s ideal for beginners learning market strategies.
Crypto Portfolio
A collection of cryptocurrencies held by an investor. Diversification across coins, tokens, and DeFi assets helps manage risk.
Candlestick Chart
Candlesticks display price movements over time, showing open, close, high, and low prices. They’re essential for technical analysis and spotting patterns.
Centralized Exchange (CEX)
Operated by a company, centralized exchanges like OKX facilitate trading by acting as intermediaries. They control order books, security, and user funds.
Correlation
This measures how two assets move in relation to each other. High correlation means they tend to rise or fall together—useful for portfolio diversification.
Coin-Margined Contracts
These derivatives use cryptocurrency (like BTC or ETH) as collateral. Profits and losses are settled in the same crypto asset.
D
DYOR (Do Your Own Research)
A core principle in crypto: always verify information independently. Never rely solely on influencers or social media tips.
Day Trading
Day traders open and close positions within the same 24-hour period, aiming to profit from short-term price fluctuations.
Dollar-Cost Averaging (DCA)
DCA involves investing fixed amounts at regular intervals, regardless of price. This reduces the impact of volatility and lowers average entry cost over time.
👉 Start practicing DCA with a secure and user-friendly trading platform.
E
ERC-20
The most widely used token standard on Ethereum. ERC-20 simplifies token creation and ensures compatibility with wallets and exchanges.
ERC-721
A standard for non-fungible tokens (NFTs), each unique and indivisible. Used for digital art, collectibles, and in-game items.
Ethereum Virtual Machine (EVM)
The EVM executes smart contracts on the Ethereum network. It’s a decentralized runtime environment enabling developers to build dApps.
F
Fiat Currency
Government-issued money like USD or EUR. To trade crypto with fiat, users typically deposit funds through regulated platforms.
FOMO (Fear of Missing Out)
FOMO drives impulsive buying when prices surge. Recognizing this emotion helps avoid poor timing and overpaying.
FUD (Fear, Uncertainty, Doubt)
Negative rumors or news that may cause panic selling. Always assess sources critically before reacting.
Fundamental Analysis (FA)
Evaluates a project’s intrinsic value based on team strength, technology, use case, tokenomics, and market potential.
Futures Trading
Allows speculation on future asset prices without owning the underlying crypto. Contracts can be settled in cash or coin.
G
Grid Trading
An automated strategy placing buy and sell orders at set price intervals, forming a "grid." Profits come from small price fluctuations within a range.
H
High / Low (24h)
The highest and lowest prices an asset reached in the past 24 hours. These values help assess short-term volatility.
Halving
Bitcoin undergoes halving every 210,000 blocks (~4 years), cutting mining rewards in half. This reduces supply inflation and historically precedes bull runs.
HODL
Short for “Hold On for Dear Life,” HODL means holding crypto long-term despite market swings. It reflects confidence in future value growth.
I
Impermanent Loss
Occurs when providing liquidity in decentralized exchanges. If asset prices change significantly, liquidity providers may end up with less value than if they’d held the assets.
K
K-Line (Candlestick)
Same as candlestick chart—visualizes price movement with body and wicks showing open/close and highs/lows.
KDJ Indicator
A momentum oscillator used to identify overbought or oversold conditions. Popular in short-term crypto and stock analysis.
L
Line Chart
Displays closing prices over time as a continuous line. Simpler than candlesticks but less detailed.
Ledger
A record of all transactions on a blockchain. Every node maintains a copy, ensuring transparency and security.
Liquidity
Refers to how quickly an asset can be bought or sold without affecting its price. High liquidity means tight spreads and fast execution.
Limit Order
An order to buy or sell at a specific price or better. Offers control over entry/exit points but may not execute if the market doesn’t reach the target.
M
Margin Trading
Borrowing funds to increase trading position size. Amplifies both gains and losses—requires careful risk management.
👉 Learn margin trading basics with step-by-step guides and live market data.
Isolated vs Cross Margin
- Cross Margin: Uses entire account balance as collateral for a position. Higher risk but reduces liquidation chances.
- Isolated Margin: Allocates specific funds to a single trade. Limits potential loss to that amount.
Market Capitalization (Market Cap)
Calculated as price × circulating supply. Used to rank projects by size and assess stability.
Mining Pool
A group of miners combining computational power to increase chances of earning block rewards in proof-of-work networks.
Moving Average (MA)
Smooths price data over time to identify trends. Common types include SMA (Simple) and EMA (Exponential).
MVRV Z-Score
Compares Bitcoin’s market value to its realized value (actual cost basis of coins). Helps determine if BTC is overvalued or undervalued.
N
Network Fee
Paid to miners or validators for processing transactions. Fees vary based on network congestion.
NVT Ratio (Network Value to Transactions)
Analogous to the P/E ratio in stocks. Measures market value relative to on-chain transaction volume—useful for spotting bubbles.
P
Paper Wallet
A physical document storing private keys offline. Once popular for cold storage, now considered outdated due to usability and security risks.
R
Return on Investment (ROI)
Measures profitability: (Current Value - Cost) / Cost × 100%. Helps evaluate performance of trades or staking rewards.
Relative Strength Index (RSI)
A momentum oscillator ranging from 0–100. RSI above 70 suggests overbought conditions; below 30 indicates oversold levels.
S
Spot Trading
Buying and selling cryptocurrencies at current market prices. Most straightforward form of trading.
Staking
Locking up crypto assets to support network operations (e.g., validating transactions) and earn rewards—common in proof-of-stake systems.
Short Selling
Selling borrowed crypto with the aim of buying it back cheaper later. Profits when prices fall.
Social Trading
Platforms allow users to follow and replicate trades of successful investors—great for learning real-world strategies.
Support and Resistance
Key price levels where buying (support) or selling (resistance) pressure increases. These zones help predict reversals or breakouts.
T
Tokenomics
Encompasses token supply, distribution, utility, incentives, and burn mechanisms. Strong tokenomics are crucial for long-term value.
Technical Analysis (TA)
Uses historical price data, charts, and indicators to forecast future movements. Widely used by traders for timing entries and exits.
Testnet
A sandbox environment for developers to test smart contracts without risking real funds. Uses “fake” tokens but mimics mainnet behavior.
Token
A digital asset built on an existing blockchain (e.g., ERC-20 on Ethereum). Differs from native coins like BTC or ETH.
TradingView Integration
Many platforms integrate with TradingView, offering advanced charting tools and community-driven insights for better decision-making.
U
UTXO (Unspent Transaction Output)
The technical basis for Bitcoin balances. Your wallet balance is the sum of unspent outputs from prior transactions.
Unit Price
The current market price of one unit of a cryptocurrency.
USDT/USDC-Margined Contracts (U-Margin)
Futures contracts settled in stablecoins. Profits and losses are denominated in USDT or USDC, reducing volatility exposure.
V
Validator
Participants in proof-of-stake networks who verify transactions and create new blocks based on staked assets. Earn rewards for honest participation.
Volatility
Measures how drastically an asset’s price fluctuates over time. High volatility offers profit opportunities but increases risk—especially for new traders.
