Here’s a basic crypto knowledge lesson.
Lesson 1: What Is Cryptocurrency?
A cryptocurrency is a digital form of money that runs on blockchain technology. It’s decentralized, meaning no bank or government controls it.
• Example: Bitcoin (BTC), Ethereum (ETH)
Lesson 2: What Is a Blockchain?
A blockchain is a digital ledger that records all crypto transactions publicly.
Think of it like a Google spreadsheet that everyone can see, but no one can secretly change.
Lesson 3: What Is a Wallet?
A crypto wallet stores your digital assets.
There are two main types:
• Hot Wallets: Connected to the internet (e.g., MetaMask, Trust Wallet)
• Cold Wallets: Offline storage (e.g., hardware wallets like Ledger)
Your private key = your money. Never share it.
Lesson 4: What Is an Exchange?
A crypto exchange is where you buy, sell, and trade cryptocurrencies.
• Centralized (CEX): Binance, Coinbase
• Decentralized (DEX): Uniswap, PancakeSwap
Lesson 5: What Is Bitcoin (BTC)?
Bitcoin is the first and most well-known cryptocurrency.
It was created in 2009 by an unknown person or group named Satoshi Nakamoto.
Purpose: Be a decentralized form of money.
Lesson 6: What Is Ethereum (ETH)?
Ethereum is more than just money. It allows developers to build smart contracts and dApps (decentralized apps).
Think of Bitcoin as digital gold, and Ethereum as digital infrastructure.
Lesson 7: What Is a Smart Contract?
A smart contract is code that automatically executes when certain conditions are met.
Example: You bet 1 ETH on a football game — the smart contract pays the winner instantly, without a third party.
Lesson 8: What Is a Token?
Tokens are built on top of blockchains like Ethereum.
They can represent anything: a currency (USDT), a meme (DOGE), or ownership (NFTs).
Lesson 9: How to Stay Safe in Crypto
• NEVER share your private key or seed phrase.
• Use two-factor authentication (2FA).
• Don’t fall for DMs offering “guaranteed profits.”
• Start small and always DYOR (Do Your Own Research).
