Digital money ideas began in the 1990s. Projects like DigiCash and e-gold attempted to create online payment systems. They failed, but they introduced the world to digital currency.

2. Bitcoin launched in 2009 & Satoshi Nakamoto

In 2009, Satoshi Nakamoto launched Bitcoin. It became the first real cryptocurrency. Bitcoin used blockchain and worked without a bank.

How Does Cryptocurrency Work?

Cryptocurrency works using technology that lets people send money directly to each other. It does not need a bank or an intermediary. All transactions are checked and stored on a public system called blockchain so that everyone can see them, but no one can cheat. It makes crypto fast, safe, and reliable for online use. Here is How Cryptocurrency Works 

1. Blockchain Technology: Every transaction is added to a digital ledger called a blockchain. Each block links to the previous one, keeping records safe and transparent.
2. Decentralization: No single person or organization controls cryptocurrency. Users worldwide share control, reducing fraud risks.
3. Mining and Creation: Some coins, like Bitcoin, are made through mining. Computers solve complex problems to confirm transactions and earn new coins.
4. Transactions: A digital wallet is used to send crypto. The network verifies the transaction, and it becomes part of the blockchain.
5. Security:
   Advanced cryptography ensures only the wallet owner can access funds. Transactions cannot be changed once they have been confirmed.
6. Global Use: Cryptocurrency operates worldwide, 24/7, without bank delays or geographical borders.
