Bitcoin (BTC) is a revolutionary virtual currency that operates on a decentralized peer-to-peer (P2P) payment system, free from central control by governments or organizations. Introduced in 2008 by the pseudonymous Satoshi Nakamoto, Bitcoin pioneered blockchain technology and remains the largest cryptocurrency by market capitalization.
How Bitcoin Works
Bitcoin functions entirely digitally via a decentralized blockchain network—a public ledger recording all transactions. Key features include:
- Decentralized Validation: Transactions are verified by nodes across the network.
- Immutable Ledger: Once recorded, transactions cannot be altered or removed.
- Proof-of-Work: Miners solve complex computations to validate blocks, earning BTC as rewards.
This system ensures security, transparency, and anonymity for users.
The Origins of Bitcoin
Created in response to the 2007–2008 financial crisis, Bitcoin aimed to establish a fairer financial system. Its foundational principles were outlined in Nakamoto’s whitepaper, Bitcoin: A Peer-to-Peer Electronic Cash System. Despite claims by various individuals, Nakamoto’s true identity remains unknown.

Innovations:
- Ordinals Protocol: Embeds data (images, videos) into individual satoshis.
- Runes Protocol (2024): Enables token creation directly on Bitcoin’s blockchain.
Bitcoin Price Dynamics
BTC’s value is driven by:
- Supply and Demand: Scarcity (limited supply) and adoption influence price.
- Market Sentiment: News and public perception significantly impact trading behavior.
- Mining Rewards: Halving events reduce mining subsidies by 50% every ~4 years (next: 2028).
