What is Cryptocurrency?
Cryptocurrency (or crypto) is a digital form of money built on blockchain technology. Unlike traditional currencies, it is decentralized, meaning no bank or government controls it. Bitcoin was the first crypto, launched in 2009, and today thousands of coins exist — including Ethereum, Solana, and BNB.
How Does Cryptocurrency Work?
Every crypto transaction is recorded on a blockchain — a secure public ledger shared across thousands of computers worldwide. This makes crypto:
✅ Transparent
✅ Hard to hack
✅ Borderless
When you send or receive crypto, your digital wallet uses private and public keys to confirm ownership.
Why is Crypto Popular?
People use crypto for:
- Trading and investment (to earn profit on price changes)
- Payments (fast and low-cost global transfers)
- DeFi (Decentralized Finance) apps — to lend, borrow, or stake coins
- NFTs and Gaming (digital collectibles & in-game assets)
Key Crypto Terms to Know

- Token – A digital asset built on another blockchain (e.g., ERC-20 tokens on Ethereum).

Is Crypto Safe?
Crypto is secure but risky.
- Your funds are only as safe as your wallet security and investment choices.
- Always enable 2FA, use cold wallets, and avoid sharing private keys.
