What Is Cryptocurrency? A Beginner’s Guide to Digital Money in 2025
Cryptocurrency is no longer just a buzzword — it's becoming a global financial revolution. In 2025, millions of people around the world are investing, spending, and saving in digital currencies like Bitcoin and Ethereum. But what exactly is cryptocurrency? In this beginner-friendly guide, we break down the basics, how it works, and why it matters today more than ever.
