BTC
**Type:** Cryptocurrency
**Technology:**
- **Blockchain:** Bitcoin operates on a decentralized blockchain, a distributed ledger that records all transactions across a network of computers (nodes).
- **Consensus Mechanism:** Proof of Work (PoW) – Miners compete to solve complex mathematical problems, and the first to solve the problem adds a new block to the blockchain and is rewarded with newly minted Bitcoin.
- **Supply Limit:** 21 million BTC (the maximum number of bitcoins that can ever be mined).
**Initial Value:**
- **Genesis Block Reward:** 50 BTC (January 3, 2009)
- **First Recorded Exchange Rate:** $0.0008 to $0.08 per BTC (early 2010)
**Key Historical Milestones:**
1. **Genesis Block (January 3, 2009):** The first block of the Bitcoin blockchain, called the Genesis Block, was mined by Satoshi Nakamoto, marking the birth of Bitcoin.
2. **First Bitcoin Transaction (January 12, 2009):** Satoshi Nakamoto sent 10 BTC to Hal Finney, a computer scientist and early Bitcoin contributor.
3. **Bitcoin Pizza Day (May 22, 2010):** The first real-world transaction using Bitcoin, where Laszlo Hanyecz paid 10,000 BTC for two pizzas, valuing BTC at $0.0025.
4. **Mt. Gox Hack (2014):** The largest Bitcoin exchange at the time, Mt. Gox, was hacked, leading to the loss of approximately 850,000 BTC and severely impacting Bitcoin’s reputation.
5. **Bitcoin Halving Events:** Halvings occur approximately every four years, reducing the block reward by half:
- **First Halving:** November 28, 2012 (block reward reduced from 50 BTC to 25 BTC).
- **Second Halving:** July 9, 2016 (block reward reduced from 25 BTC to 12.5 BTC).
- **Third Halving:** May 11, 2020 (block reward reduced from 12.5 BTC to 6.25 BTC).
- **Fourth Halving (Expected):** Around April 2024 (block reward will reduce from 6.25 BTC to 3.125 BTC).
6. **Bitcoin’s All-Time High (November 10, 2021):** Bitcoin reached an all-time high of approximately $68,789.63.
### **Current Status (2024):**

### **Key Features:**
- **Decentralization:** No central authority controls Bitcoin; it is governed by its users through a distributed consensus mechanism.
- **Transparency:** All Bitcoin transactions are publicly recorded on the blockchain, allowing for transparency and traceability.
- **Security:** Bitcoin’s blockchain is secured by cryptographic techniques, making it resistant to fraud and hacking.
- **Scarcity:** With a fixed supply of 21 million coins, Bitcoin is often compared to gold, leading to its nickname "digital gold."
### **Future Outlook:**

- **Scalability Challenges:** Ongoing developments like the Lightning Network aim to address Bitcoin's scalability issues, making transactions faster and cheaper.
