Cryptocurrency: Introduction

Cryptocurrency is a form of digital currency that runs without control by any central authority, like a bank or government. It relies on blockchain technology—a decentralized, encrypted ledger that validates and records all transactions transparently and securely (New York Post). From Bitcoin and Ethereum to stablecoins, cryptos enable peer‑to‑peer payments, global access, and innovation in areas such as smart contracts, decentralized finance (DeFi), and NFTs .

While crypto offers high growth potential and financial inclusion, it also brings risks—extreme volatility, regulatory uncertainty, hacking threats, and environmental concerns .
