Crypto and digital assets

A grounded, hype-free introduction to cryptocurrency, covering how it works, the real risks, and where it fits for a beginner.

What is cryptocurrency?

Cryptocurrency is a form of digital money that isn't issued or run by a bank or government. Instead of a central authority keeping track of who owns what, a network of computers around the world maintains the records together, agreeing on the current state of every account through a shared set of rules rather than one company's internal database.
