What Is Bitcoin?

Bitcoin (BTC) is the first cryptocurrency, created in 2009 by a person or group using the pseudonym Satoshi Nakamoto. It’s controlled by no central bank or government and runs on a decentralized network.

It’s the most valuable and most recognized cryptocurrency ever created. With a capped supply of 21 million, it’s often compared to gold.

How Does Bitcoin Work?

Bitcoin operates on a blockchain using a Proof of Work mechanism. Miners compete using computing power to validate transactions. Successful miners earn newly created Bitcoin.

Every transaction is recorded on the blockchain - those records are transparent, immutable, and permanent.

Why Is Bitcoin Valuable?

  • Fixed supply: No more than 21 million Bitcoin will ever exist
  • Decentralization: No single authority controls it
  • Security: One of the most secure blockchain networks
  • Adoption: The most widely accepted cryptocurrency
  • Inflation hedge: Some investors treat Bitcoin as digital gold

Key Bitcoin Facts

  • Symbol: BTC
  • Maximum supply: 21 million BTC
  • Block time: ~10 minutes
  • Halving: Every ~4 years, miner rewards are cut in half
  • Divisibility: 1 BTC = 100,000,000 satoshi
