How Does Bitcoin Work?
Mining and Blockchain
Bitcoin relies on mining, a computational process where computers solve complex mathematical problems to validate transactions. Successful mining:
- Adds entries to Bitcoin’s blockchain (a public ledger).
- Creates new bitcoins as a reward.
However, Bitcoin has a capped supply—only 21 million will ever exist.
Bitcoin's Limited Supply
| Mining Period | Bitcoins Generated per Block |
|---|---|
| 2009–2012 | 50 BTC |
| 2012–2016 | 25 BTC |
| 2016–2020 | 12.5 BTC |
| 2020–2024 | 6.25 BTC |
The final bitcoin is expected to be mined around 2140.
Bitcoin’s Value
Bitcoin’s price fluctuates constantly. As of writing:
- 1 BTC ≈ $693 USD
- Historically, Bitcoin has surged as high as $1,116** and dropped below **$500.
What Can You Buy with Bitcoin?
Bitcoin is accepted by major companies, including:
- Overstock.com (online retail)
- Tesla (briefly accepted BTC for cars)
- Sacramento Kings (NBA tickets & concessions)
However, Bitcoin has also been used for illegal transactions, such as:
- Darknet purchases (drugs, weapons)
- Money laundering
Storing Bitcoin
Bitcoin is digital-only—no physical coins exist (though novelty items do). Users store Bitcoin in digital wallets, secured by:
- Public keys (like a username)
- Private keys (like a password—never share this!)
Risks of Bitcoin
- Market Volatility – Prices swing wildly.
- Theft – Hackers target exchanges & wallets.
- No FDIC Insurance – Lost BTC cannot be recovered.
Mt. Gox: A Cautionary Tale
Mt. Gox was once the largest Bitcoin exchange before collapsing in 2014 due to:
- Poor security
- $460 million in stolen Bitcoin
This incident highlighted Bitcoin’s security risks and lack of regulation.
Is Bitcoin Legal?
Yes—but governments are watching closely.
- U.S. Senate hearings have discussed Bitcoin regulation.
- Federal Reserve Chair Janet Yellen stated Bitcoin is outside traditional banking oversight.
The lack of central control is both a strength and a concern for regulators.
