Bitcoin Overview
What is Bitcoin (BTC)?
Bitcoin (BTC) is a decentralized digital currency that operates without central bank or government control. Launched in 2009, it introduced blockchain technology to enable secure peer-to-peer transactions through cryptographic verification.
Key characteristics:
- Limited supply: Capped at 21 million coins
- Pseudonymous creator: Developed by Satoshi Nakamoto (identity remains unknown)
- Transparent ledger: All transactions recorded publicly on the blockchain
- Deflationary design: Halving events reduce new supply every 4 years
How Bitcoin Works
The Bitcoin network processes transactions through these steps:
- Users initiate transactions via cryptocurrency wallets
- Miners verify transactions by solving complex mathematical problems
- Verified transactions bundle into blocks (~10 minutes/block)
- Blocks chain together forming an immutable public ledger

Bitcoin Mining Explained
Mining serves two critical functions:
- Transaction validation: Miners confirm legitimate transactions
- New coin issuance: Miners earn BTC rewards for adding blocks to the chain
Current mining statistics:
| Metric | Value |
|---|---|
| Block reward | 6.25 BTC |
| Hash rate | ~400 EH/s |
| Next halving | 2024 (est.) |
Understanding Bitcoin Halving
The halving mechanism:
- Occurs every 210,000 blocks (~4 years)
- Reduces block rewards by 50%
- Creates programmed scarcity (only 32 halvings possible)
Historical price impact:
| Halving Year | Pre-Event Price | Post-Event Price (1Y) |
|---|---|---|
| 2012 | $12 | $1,000 |
| 2016 | $650 | $2,500 |
| 2020 | $8,500 | $58,000 |
