Crypto: From a Digital Currency Concept to a Global Financial Revolution
Cryptocurrencies were first introduced in 2008 with the publication of the Bitcoin whitepaper by the pseudonymous Satoshi Nakamoto. What began as a decentralized alternative to traditional money has evolved into a transformative force reshaping global finance, technology, and digital interaction.
At its core, cryptocurrency is a form of digital money built on blockchain technology a secure, transparent, and immutable ledger. Bitcoin pioneered this concept by enabling peer-to-peer value transfer without relying on banks or intermediaries. Soon after, Ethereum took the technology further by introducing smart contracts, allowing developers to build decentralized applications (dApps) across finance, gaming, identity, and beyond.
