Cryptocurrency, often called crypto, is a digital form of money that uses blockchain technology to secure and verify transactions. Unlike traditional currencies issued by governments, cryptocurrencies operate on decentralized networks, making them fast, transparent, and resistant to control by any single authority.
How Cryptocurrency Works
Cryptocurrencies run on blockchain, a distributed digital ledger that records every transaction across multiple computers. Each transaction is verified by network participants, which ensures security and prevents fraud.
When you buy crypto, your ownership is stored in a digital wallet. You can use crypto for trading, investing, payments, or transferring money globally.
Popular Cryptocurrencies
While thousands of cryptocurrencies exist, the most well-known include:
- Bitcoin (BTC)
- Ethereum (ETH)
- Binance Coin (BNB)
- Solana (SOL)
- Ripple (XRP)
- Cardano (ADA)
- Dogecoin (DOGE)
Bitcoin is the first and largest, while Ethereum is famous for smart contracts and decentralized apps.
