Introduction to Cryptocurrencies
Cryptocurrencies, also known as virtual currencies, are digital assets that use cryptographic techniques to secure transactions and control the creation of new units. Unlike traditional fiat currencies issued by central banks, cryptocurrencies operate on decentralized networks powered by blockchain technology. This ensures transparency, immutability, and global accessibility without intermediaries.
Key types of cryptocurrencies include:
- Major Coins: High-market-cap assets like Bitcoin (BTC) and Ethereum (ETH).
- Stablecoins: Pegged to fiat currencies (e.g., USDT) to minimize volatility.
- Altcoins: Alternative coins with smaller market capitalizations.
