Navigating the cryptocurrency landscape can be daunting, especially for newcomers. This comprehensive glossary breaks down key concepts, from blockchain fundamentals to advanced trading strategies, ensuring you're equipped to explore the crypto ecosystem with confidence.
Core Blockchain & Cryptocurrency Concepts
1. Blockchain
A decentralized digital ledger recording transactions across a network of computers. Blockchains enable secure, transparent data storage without centralized control—most famously powering cryptocurrencies like Bitcoin.
2. Cryptocurrency
Digital currencies secured by cryptographic encryption. Unlike traditional money, cryptocurrencies operate on decentralized networks (typically blockchains) and are mined or traded via exchanges.
3. Decentralization
The distribution of control across a network rather than relying on central authorities (e.g., banks). Decentralization enhances security and reduces single points of failure.
4. Smart Contracts
Self-executing code on blockchains that automates agreements (e.g., releasing funds when conditions are met). Ethereum pioneered their widespread use.
5. Tokenomics
The economic model governing a cryptocurrency, including supply mechanisms, utility, and distribution.
Trading & Investment Terms
6. FOMO (Fear of Missing Out)
Emotion-driven trading when prices surge, often leading to impulsive buys at peak values.
7. HODL
Slang for holding assets long-term despite market volatility (originating from a misspelled "hold" in a Bitcoin forum).
8. Altcoin
Any cryptocurrency other than Bitcoin (e.g., Ethereum, Solana).
9. Stablecoin
Cryptocurrencies pegged to stable assets like the US dollar (e.g., USDT, USDC) to minimize volatility.
10. Market Cap
Total value of a cryptocurrency: Price × Circulating Supply.
DeFi & Advanced Concepts
11. DeFi (Decentralized Finance)
Financial services (lending, trading) built on blockchains, eliminating intermediaries like banks.
12. TVL (Total Value Locked)
The sum of assets deposited in DeFi protocols, indicating ecosystem growth.
13. Impermanent Loss
Temporary loss experienced by liquidity providers due to price fluctuations in trading pools.
14. NFT (Non-Fungible Token)
Unique digital assets representing ownership (e.g., art, collectibles) on blockchains.
15. DAO (Decentralized Autonomous Organization)
Community-governed entities managed via blockchain voting.
Tax & Regulatory Terms
16. Capital Gains Tax
Tax on profits from selling crypto. Short-term (<1 year) rates are typically higher than long-term.
17. FIFO/LIFO
Accounting methods for calculating gains: First-In-First-Out vs. Last-In-First-Out.
18. KYC (Know Your Customer)
Identity verification required by exchanges to comply with anti-money laundering laws.
19. Travel Rule
Regulation mandating crypto exchanges share sender/receiver data for transactions above threshold amounts.
Security & Risks
20. Rug Pull
Scam where developers abandon a project after attracting investor funds, crashing the token’s value.
21. Cold Wallet
Offline storage (e.g., hardware devices) for cryptocurrencies, highly secure against hacks.
22. 51% Attack
When a single entity controls most of a blockchain’s mining power, enabling transaction manipulation.
23. Dusting Attack
Spam transactions sent to wallets to deanonymize holders by tracing activity.
