What is Bitcoin?
🟠 What is Bitcoin?
Bitcoin (BTC) is the world’s first and most well-known cryptocurrency.
It’s often called “digital gold” because it’s:
- Limited in supply
- Decentralized
- Used as a store of value
Created in 2009, Bitcoin allows people to send and receive peer-to-peer digital money without a bank or government.
🧑💻 Who Created Bitcoin?
Bitcoin was invented by a mysterious figure (or group) named Satoshi Nakamoto.
To this day, nobody knows who they are.
In 2008, Nakamoto published a white paper titled:
📄 “Bitcoin: A Peer-to-Peer Electronic Cash System”
The first Bitcoin block (called the Genesis Block) was mined on January 3, 2009 — and history was made.
🏦 Why Was Bitcoin Created?
Bitcoin was created in response to the 2008 financial crisis as an alternative to the traditional banking system.
Main goals:
- Give people financial freedom
- Avoid inflation caused by money printing
- Remove the need for middlemen (banks, governments)
🔗 How Does Bitcoin Work?
Bitcoin runs on a blockchain — a public digital ledger that records every transaction.
It’s powered by a network of computers (called nodes) that validate and record each transaction.
Key terms:
- Blockchain: Like a shared Google doc for money
- Mining: The process of verifying transactions and earning new BTC
- Wallet: An app or device that stores your Bitcoin securely
💰 Why is Bitcoin Valuable?
- Limited Supply – Only 21 million Bitcoins will ever exist.
- Decentralized – No one can control or shut it down.
- Secure – Uses advanced encryption and thousands of independent nodes.
- Global – Accessible to anyone with internet.
- Scarcity – Like gold, but digital and easier to transfer.
📉 Is Bitcoin Too Volatile?
Bitcoin’s price can go up or down very fast. This is because:
- It’s still a young technology
- Media hype and news can cause spikes
- Supply and demand are always shifting
That’s why many see Bitcoin as a long-term investment rather than quick cash.
