🔑 Key Facts About Bitcoin
1. What It Is
A peer-to-peer electronic cash system.
Runs on a blockchain, which is a public, tamper-resistant digital ledger.
Every Bitcoin transaction is recorded and visible to anyone using the network.
2. Supply Limit
Total supply is capped at 21 million BTC, making it scarce.
This limit is hard-coded into Bitcoin’s protocol and cannot be changed without consensus.
3. Mining Process
Bitcoins are created through a process called mining, where computers solve complex math problems.
Miners validate transactions and secure the network in exchange for BTC rewards (which halve approximately every 4 years—this is called the halving event).
4. Volatility
Bitcoin’s price is highly volatile, often moving dramatically based on news, adoption trends, macroeconomic events, or regulatory developments.
5. Use Cases
Store of value (“digital gold”)
Hedge against inflation
International remittance
Some use it for payments, but adoption in commerce remains limited

Open source: Anyone can review or propose changes to the code.
Censorship-resistant: Transactions can't easily be blocked or reversed.

⚠️ Risks & Criticisms
Price swings make it risky for short-term use.
Regulatory uncertainty in many countries.
Environmental impact of mining (though this is decreasing with cleaner energy use).
Used for illicit activities in the early years—but now far less so as regulation and compliance have caught up.
