What Cryptocurrency Is and Why It Matters

Cryptocurrency is a form of digital money that uses software, cryptography, and a distributed network instead of a single central operator. In this lesson, you will learn the basic idea behind crypto, how it differs from cash and bank money, and why people use it for payments, savings, and access to digital services.

We will also look at the main reasons cryptocurrency matters: it can move across borders quickly, it can be open to anyone with an internet connection, and it creates new ways to store and transfer value online. The lesson stays focused on the big picture so later lessons can explore blockchain, wallets, transactions, and risks in more detail.
