1. What is Crypto & Why It Matters

Cryptocurrencies are digital assets secured by cryptography and powered by decentralized networks called blockchains.

• Decentralized: No single entity controls the system.
• Transparent: All transactions are publicly recorded.
• Global & Borderless: Accessible anywhere with internet.

Blockchain Explained

A blockchain is a chain of blocks, each containing verified transactions. Each block references the previous one, making it nearly impossible to alter past data.

Core Components:

• Nodes – computers running the network.
• Consensus – how nodes agree on valid transactions.
• Immutable ledger – tamper-resistant record of transactions.

2. How Anyone Can Earn with Crypto

Entry-Level Methods

• Learning Rewards: Earn tokens by completing educational modules (e.g., Coinbase Earn).
• Microtasks & Airdrops: Participate in early-stage projects for free tokens.
• Play-to-Earn: Games that reward players with crypto assets.

Passive Strategies

• Staking: Lock tokens and earn percentage yield.
• Yield Farming: Provide liquidity and earn fees via DeFi platforms.
• Savings Accounts: Deposit stablecoins in high-interest protocols.

Active Involvement

• Trading: Buy/sell with strategies like DCA or swing trading.
• NFT Creation: Mint and resell digital art and collectibles.

3. Staying Safe: Wallets, Exchanges & Best Practices

Choosing a Wallet

• Hot Wallets: Easy access (e.g., MetaMask, Trust Wallet).
• Cold Wallets: Hardware devices like Ledger or Trezor.

Using Exchanges

• Top Platforms: Coinbase, Kraken, Binance.

Staying Secure

• Never share your private keys or seed phrases.
