🔍 What is Cryptocurrency?

Cryptocurrency is a digital or virtual form of currency that uses cryptography for security. Unlike traditional currencies like the US dollar or euro, cryptocurrencies are decentralized and operate on blockchain technology — a public, transparent ledger system.

Bitcoin, created in 2009, was the first cryptocurrency. Since then, thousands of cryptocurrencies like Ethereum, Binance Coin, and Solana have emerged.

💡 How Does It Work?

Cryptocurrencies use blockchain technology to store and verify transactions. Every transaction is recorded in a block and added to a chain, ensuring transparency and security. These transactions are verified by a process called mining, done by powerful computers.

Unlike banks, there’s no central authority. This makes transactions:

Faster

Borderless

Often cheaper
