Introduction to Bitcoin (BTC)
Bitcoin (BTC) is a decentralized digital currency created in 2008 following the global financial crisis. As the first successful implementation of cryptocurrency, it introduced groundbreaking concepts like blockchain technology and peer-to-peer electronic cash systems.
Key Characteristics of Bitcoin:
- Decentralized: No central authority controls Bitcoin
- Limited Supply: Fixed maximum supply of 21 million coins
- Pseudonymous: Transactions don't require personal identification
- Global: Can be transferred worldwide without borders
- Secure: Cryptographic protection prevents counterfeiting
The History and Creation of Bitcoin
Bitcoin was conceived by the pseudonymous Satoshi Nakamoto, who published the famous whitepaper "Bitcoin: A Peer-to-Peer Electronic Cash System" in October 2008. The network officially launched on January 3, 2009 when Nakamoto mined the genesis block (Block 0), receiving a 50 BTC reward.
Bitcoin Halving Schedule
| Block Height | Reward Amount | Approximate Date |
|---|---|---|
| 0-210,000 | 50 BTC | 2009-2012 |
| 210,001-420,000 | 25 BTC | 2012-2016 |
| 420,001-630,000 | 12.5 BTC | 2016-2020 |
| 630,001-840,000 | 6.25 BTC | 2020-2024 |
The next halving is expected around April 2024, reducing the block reward to 3.125 BTC. This scheduled scarcity is fundamental to Bitcoin's value proposition.
