Whether you're just curious or ready to invest, understanding these terms is essential. Let's dive in! 🌊

🔗 What is Cryptocurrency?

Cryptocurrency is a type of digital or virtual money that uses cryptography to secure transactions. Unlike traditional currencies issued by governments (fiat), cryptocurrencies are typically decentralized and run on a technology called blockchain.

💡 Why It Matters

Cryptocurrencies offer a new financial system that is borderless, decentralized, and accessible to anyone with an internet connection. Understanding crypto terms will help you make informed decisions and avoid common pitfalls.

📘 Essential Crypto Terms You Should Know

Here is a beginner-friendly glossary of the most common and important terms in crypto:

🔗 Blockchain

A distributed digital ledger that records all cryptocurrency transactions across a network of computers. It is transparent, immutable, and the backbone of most crypto projects.

🪙 Coin vs Token

• Coin: A cryptocurrency that runs on its own blockchain (e.g., Bitcoin, Ethereum).
• Token: A digital asset built on an existing blockchain (e.g., USDT on Ethereum).

👛 Wallet

A tool (software or hardware) that stores your cryptocurrency. Comes in two types: custodial (managed by a third party) and non-custodial (you control your private keys).

📈 Exchange

A platform where you can buy, sell, or trade cryptocurrencies. Examples include Binance, Coinbase, and Kraken.

🔐 Private Key / Public Key

• Public Key: Your wallet address. You can share this to receive crypto.
• Private Key: A secret code that allows access to your crypto. Never share this!

⛽ Gas Fee

A small fee paid to process transactions on a blockchain network, especially Ethereum. Gas fees can vary depending on network congestion.

📜 Smart Contract

A self-executing contract with coded terms directly on the blockchain. Enables decentralized applications (dApps) to function without intermediaries.

💼 DeFi (Decentralized Finance)

Financial services built on blockchain without centralized institutions. You can lend, borrow, and trade crypto directly with others.

🎢 Volatility

Crypto markets are known for being highly volatile — prices can change rapidly within minutes. High risk, high reward.

🧍 HODL

A slang term that means "Hold On for Dear Life" — keep your crypto long-term regardless of short-term price swings.

😱 FOMO (Fear of Missing Out)

Buying a coin impulsively because it’s rapidly going up in value. Often leads to buying at the top.

🐻 Bear Market / 🐂 Bull Market

• Bear Market: A market in decline — prices falling.
• Bull Market: A market in uptrend — prices rising.

🧱 Layer 1 / Layer 2

• Layer 1: The base blockchain (e.g., Ethereum, Solana).
• Layer 2: Built on top of Layer 1 to improve scalability (e.g., Polygon, Arbitrum).

🔄 Swap

Exchanging one cryptocurrency for another — usually done via decentralized exchanges like Uniswap.

🧑‍🌾 Yield Farming / Staking

• Staking: Locking your tokens to help secure a blockchain and earn rewards.
• Yield Farming: Moving funds across DeFi protocols to earn the highest returns.

📉 Rug Pull

A type of scam where developers abandon a project and run away with investors’ funds. Always research before investing!

🛡️ Security Terms

🧾 Seed Phrase

A series of 12–24 words that act as a backup to access your wallet. Write it down and store it offline.

🔒 Cold Wallet / Hot Wallet

• Cold Wallet: Offline storage (e.g., hardware wallet) — safer from hacks.
• Hot Wallet: Online wallet — more convenient, but riskier.

⚠️ Phishing

A cyberattack where scammers trick you into giving up your login info or seed phrase. Always double-check URLs and never click on suspicious links.
