Bitcoin (BTC) revolutionized digital finance as the world's first decentralized peer-to-peer (P2P) cryptocurrency. Created in 2008 by the pseudonymous Satoshi Nakamoto, Bitcoin introduced blockchain technology—a transparent, immutable ledger system that operates without central authority. Today, BTC maintains the highest market capitalization among cryptocurrencies.
How Bitcoin Works
Bitcoin exists entirely digitally, powered by a decentralized blockchain network. Here's the operational framework:
- Transactions: Verified by nodes and grouped into blocks
- Proof-of-Work: Mining process securing the network
- Immutability: Blocks permanently recorded on the public ledger
- Anonymity: Pseudonymous transactions protect user privacy

- Fixed supply of 21 million coins
- Democratic access through P2P networks
The creator's true identity remains unknown despite numerous claims.

Bitcoin Tokenomics and Pricing Factors
BTC's value derives from:
| Factor | Impact |
|---|---|
| Fixed Supply | 21 million cap creates scarcity |
| Mining Rewards | Halving events reduce new supply |
| Market Demand | Adoption drives price movements |
| Sentiment | News/events influence trading behavior |
Mining process:
- Computers solve complex equations
- Successful miners earn BTC rewards
- Security maintained through decentralization
Understanding Bitcoin Halving
The quadrennial event reduces mining rewards by 50%. Historical halvings:
| Year | Block Reward Before | Block Reward After | Subsequent Price Increase |
|---|---|---|---|
| 2012 | 50 BTC | 25 BTC | 12,400% |
| 2016 | 25 BTC | 12.5 BTC | 5,200% |
| 2020 | 12.5 BTC | 6.25 BTC | 1,200% |
| 2024 | 6.25 BTC | 3.125 BTC | TBD |
The next halving is projected for 2028, reducing rewards to 1.5625 BTC per block.
