### **What Are Digital Currencies?**
Digital currencies are electronic money used over the internet, with no physical form. They are classified into three main types:
1. **Cryptocurrencies**: Such as Bitcoin and Ethereum, which rely on **blockchain** technology to securely and decentralize transaction records.
2. **Stablecoins**: Like Tether, which peg their value to physical assets (such as gold or the U.S. dollar) to avoid volatility.
3. **Central Bank Digital Currencies (CBDCs)**: Government-led projects, such as China’s digital yuan, aiming to merge technological benefits with central bank oversight.
