Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments, cryptocurrencies operate on decentralized systems, often built on blockchain technology.

Key Features of Cryptocurrency:

• Decentralization: No central authority or government controls cryptocurrencies.
• Transparency: Blockchain technology allows transactions to be recorded on public ledgers, enhancing traceability.
• Anonymity: While transactions are transparent, user identities remain pseudonymous.
• Limited Supply: Many cryptocurrencies, like Bitcoin, have a capped supply, ensuring scarcity.

The Birth of Cryptocurrency

The concept of cryptocurrency dates back to the 1980s with the development of digital cash. However, it wasn’t until 2009 that Bitcoin, the first cryptocurrency, was introduced by an anonymous individual or group under the pseudonym Satoshi Nakamoto.

Timeline of Cryptocurrency Development:

• 2009: Bitcoin launches, marking the first decentralized cryptocurrency.
