Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. It operates on decentralized systems, typically using blockchain technology, which ensures transparency, immutability, and security in transactions. Unlike traditional currencies, cryptocurrencies are not controlled by central banks or governments.
Key Features of Cryptocurrencies
- Decentralization: No central authority manages or controls cryptocurrencies.
- Security: Transactions are encrypted and secured using advanced cryptographic techniques.
- Transparency: Most cryptocurrencies operate on public blockchains, allowing anyone to view transactions.
- Anonymity/Pseudonymity: Users can make transactions without revealing personal information.
- Global Access: Cryptocurrencies can be used anywhere with an internet connection.
