What is Cryptocurrency?
Cryptocurrency is a digital or virtual currency secured by cryptography. Unlike traditional money issued by governments, cryptocurrencies operate on decentralized networks using blockchain technology.
The first cryptocurrency, Bitcoin, was introduced in 2009 by an anonymous creator known as Satoshi Nakamoto. Bitcoin was designed to allow peer-to-peer payments without banks or intermediaries.
Today, there are thousands of cryptocurrencies, each serving different purposes.

Each block contains:
