🪙 Section 1: What Is Cryptocurrency?
Cryptocurrency is a digital form of money that uses cryptography (advanced math and coding) to secure transactions. Unlike traditional currencies such as the British Pound or US Dollar, cryptocurrencies are not issued by governments or central banks. Instead, they are maintained by decentralized computer networks all over the world.
🔍 So… What Makes It Different?
| Traditional Currency | Cryptocurrency |
|---|---|
| Centralized (controlled by governments or banks) | Decentralized (controlled by a network of users) |
| Requires intermediaries (banks, payment processors) | Peer-to-peer (you send directly to others) |
| Inflation-prone due to unlimited printing | Many have fixed supply (e.g. Bitcoin: 21 million max) |
| Can be censored or blocked | Transactions are borderless, censorship-resistant |
| Relatively private | Pseudonymous (linked to wallet addresses, not names) |
🧠 Cryptocurrency in Plain Terms
Think of cryptocurrency as digital cash that you can send and receive without a bank. Each transaction is recorded on a public digital ledger called the blockchain, which is like a massive, tamper-proof receipt book shared by thousands of computers.
When you send someone Bitcoin, for example, you’re not handing over a coin. Instead, you’re updating the ledger to say, “I no longer own this, now they do.”
🧱 Real-World Example:
Imagine you want to send £100 to a friend in another country.
- With a bank: You deal with delays, exchange rates, and fees.
- With crypto: You send Bitcoin or another coin, and it’s received in minutes — often with lower fees and no middlemen.
🪙 Popular Cryptocurrencies
There are thousands of cryptocurrencies, but here are a few you’ll hear about often:
| Name | Symbol | Key Use |
|---|---|---|
| Bitcoin | BTC | The original crypto, digital gold |
| Ethereum | ETH | Powers smart contracts and apps |
| Tether | USDT | Stablecoin pegged to USD |
| Solana | SOL | Fast blockchain for DeFi and NFTs |
| Ripple (XRP) | XRP | Cross-border payments |
Each has different functions — some are currencies, others are platforms for applications, and some are meant to remain stable in value.
