Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments (like the dollar or euro), cryptocurrencies are typically decentralized and operate on technology called blockchain. The blockchain is a distributed ledger that records all transactions across a network of computers.
Here are some key points about cryptocurrency:
1. **Bitcoin**: The first and most well-known cryptocurrency, created in 2009 by an anonymous person or group known as Satoshi Nakamoto.
2. **Ethereum**: A platform that enables smart contracts and decentralized applications (dApps) beyond just a currency. It was proposed by Vitalik Buterin in 2013.
3. **Altcoins**: These are alternative cryptocurrencies to Bitcoin, such as Ripple (XRP), Litecoin (LTC), and Cardano (ADA).
4. **Wallets**: Digital wallets are used to store and manage your cryptocurrencies. They can be software-based (online or desktop apps) or hardware-based (physical devices).
5. **Exchanges**: Platforms where you can buy, sell, or trade cryptocurrencies. Examples include Coinbase, Binance, and Kraken.
6. **Mining**: The process of validating transactions and securing the blockchain network, often requiring significant computational power.
7. **Volatility**: Cryptocurrencies can experience significant price fluctuations, which can lead to both high rewards and high risks.
