Introduction
Cryptocurrencies are shaking up money as we know it, offering a secure, decentralized way to pay and invest. But what’s crypto really about, and why should you care? This guide explains the basics: cryptocurrencies are digital currencies that use cryptography for security and operate on decentralized networks. Let’s dive in and explore this exciting world!
What is Cryptocurrency?
Cryptocurrency is digital money secured by cryptography, making it tough to fake. Unlike dollars or euros, it’s not controlled by any government or bank. It uses blockchain—a shared, tamper-proof record of every transaction. Bitcoin, launched in 2009 by the mysterious Satoshi Nakamoto, was the first. Now, thousands of coins like Ethereum, Ripple, and Dogecoin are out there, each with cool features.
- Bitcoin started it all. It’s like digital gold.
- Blockchain keeps things honest. Everyone sees the same ledger.
- Altcoins spice things up. They do more than just payments.
