What is Cryptocurrency?
Cryptocurrency, in simple terms, is digital or virtual money. It’s a form of payment that can be exchanged online for goods and services. Unlike traditional currencies, cryptocurrencies operate independently of a central authority, such as a government or financial institution.
The most famous cryptocurrency is Bitcoin, which was created in 2009. Since then, thousands of other cryptocurrencies, often referred to as altcoins, have been developed. Each cryptocurrency has its unique features, but they all share the common principle of being decentralized.
How Does Cryptocurrency Work?
Cryptocurrency operates on a technology called blockchain. Think of blockchain as a digital ledger that records all transactions across multiple computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network.
Digital Wallets: To use cryptocurrency, you need a digital wallet. This is a software program where you can store your public and private keys. Public keys are used to receive cryptocurrency, while private keys are used to send it.
Transactions: When you send cryptocurrency to someone, the transaction is broadcast to the network. Miners, who are users that use their computers to help validate and record transactions, then compete to solve complex mathematical problems. The first to solve the problem gets to add the transaction to the blockchain and earns a reward in cryptocurrency.
Blockchain: Once a transaction is confirmed by the network, it is added to the blockchain as a new block. This block is then linked to the previous block, creating a chain of blocks that contains a record of all transactions.

- Bitcoin (BTC): The first and most well-known cryptocurrency, known for its decentralized nature and limited supply.
