Cryptocurrency is a digital currency secured by cryptography, operating on decentralized networks without central banks or governments. Powered by blockchain technology, it offers secure, transparent transactions. In 2025, it extends to smart contracts and NFTs, broadening its influence.
Key Features
- Decentralization: Maintained by thousands of global nodes (e.g., Bitcoin’s 15,000).
- Security: Protected by advanced encryption like ECC.
- Programmability: Ethereum’s smart contracts expand its utility.
- Limited Supply: Bitcoin’s 21 million cap (19.7 million mined by 2025) resists inflation.
The Evolution of Cryptocurrency: From Origins to 2025
The Birth of Cryptocurrency
