1. Blockchain Technology: Most cryptocurrencies operate on a decentralized ledger called blockchain, which records all transactions across a network of computers.
2. Types of Cryptocurrencies: The most well-known is Bitcoin, but there are thousands of others, including Ethereum, Ripple, and Litecoin, each with unique features and uses.
3. Wallets: To store and manage cryptocurrencies, users need a digital wallet, which can be software-based (online or mobile) or hardware-based (offline).
4. Investing: People buy cryptocurrencies as an investment, hoping their value will increase. However, the market is highly volatile.
5. Mining and Staking: Some cryptocurrencies are created through mining (solving complex mathematical problems) or staking (holding coins to support network operations).
6. Regulation: The regulatory environment for cryptocurrencies varies by country, affecting their legality and use.
