The first decentralized cryptocurrency, created in 2009 by Satoshi Nakamoto

The first decentralized cryptocurrency, created in 2009 by Satoshi Nakamoto.

Bitcoin introduced the concept of a peer-to-peer electronic cash system that operates without a central authority. It uses blockchain technology and proof-of-work consensus to enable secure, transparent transactions between parties anywhere in the world.

Key Features

  • Fixed Supply: Maximum of 21 million BTC will ever exist
  • Decentralized: No central authority controls the network
  • Transparent: All transactions are recorded on a public blockchain
  • Secure: Protected by cryptographic algorithms and distributed consensus

Why It Matters

Bitcoin pioneered the entire cryptocurrency industry and remains the largest cryptocurrency by market capitalization. It's often referred to as "digital gold" due to its store of value properties and limited supply.

While Bitcoin's price volatility makes it challenging for everyday transactions, it has established itself as a hedge against inflation and a global, borderless form of money that operates 24/7 without intermediaries.
