Introduction to Bitcoin
Bitcoin (BTC) is the world's first decentralized cryptocurrency, created in 2008 by the mysterious Satoshi Nakamoto as a response to the global financial crisis. This digital currency operates without central banks or governments, using blockchain technology to enable peer-to-peer transactions.
Key Characteristics:
- Decentralized: No single entity controls the network
- Limited Supply: Capped at 21 million coins
- Pseudonymous: Transactions don't reveal personal identities
- Global: Can be sent anywhere in the world
- Low Fees: Minimal transaction costs compared to traditional systems
How Bitcoin Works
The Bitcoin network relies on a process called "mining" to validate transactions and create new coins. Miners use specialized computers to solve complex mathematical problems that verify blocks of transactions. Successful miners receive newly minted bitcoins as reward.
