Chapter 1: What Bitcoin Is and Why It Matters
What Is Bitcoin?
Bitcoin is digital money that lives on the internet.
- No paper coins or bills
- Not issued by any government
- People send it directly to each other
Key idea: Bitcoin is a money system that runs on computers around the world, not in a single bank.
Why Was Bitcoin Created?
Bitcoin appears after the 2008 financial crisis.
Problems it tries to fix:
- Banks can block or delay payments
- Governments can print more money
- People may not fully trust middlemen
Bitcoin aims to be money that is:
- Hard to create
- Easy to verify
- Independent from any one country.
Key Features of Bitcoin
Bitcoin is:
- Digital: exists as data, not metal
- Scarce: only 21 million can ever exist
- Borderless: works across countries
- Open: anyone can use or build on it
Takeaway: Bitcoin acts like "internet money" with rules written in code instead of laws alone.
Who Controls Bitcoin?
Surprisingly, no one person or company owns Bitcoin.
- The code is open source
- Thousands of computers (nodes) run it
- Changes need broad agreement
This is called decentralization.
> In Bitcoin, rules matter more than rulers.
Power is spread across the network, which helps resist censorship and corruption.
