What Is Cryptocurrency? Beginner’s Guide to Digital Money (2025)

by | Sep 16, 2025 | Informational

Cryptocurrency is one of the most talked-about things in finance and technology right now. But a lot of newcomers still want to know the big question: “What is cryptocurrency?”

Cryptocurrency is a type of digital money that functions on a decentralized basis, which means that no one bank or government controls it. Transactions are instead stored on a blockchain, which is a digital ledger that is both safe and clear.


How Does Cryptocurrency Work?

Blockchain technology is what makes cryptocurrency work. A network of computers checks each transaction, making it almost hard to change. You may send and receive money digitally from anywhere in the globe using crypto, so you don’t have to carry cash or swipe a bank card tied to a bank account.


Types of Cryptocurrency

There are thousands of cryptocurrencies, but the most popular include:

  • Bitcoin (BTC): The first and most valuable cryptocurrency.
  • Ethereum (ETH): Known for smart contracts and powering decentralized apps.
  • Tether (USDT): A stablecoin pegged to the U.S. dollar.
  • Solana (SOL): A fast blockchain for apps and payments.
