1. Bitcoin & Nationwidee Concepts & Current Insights

2. What is Bitcoin? Digital, decentralized cryptocurrency No central authority or bank controls it Symbol: BTC ₿

3. Who Created Bitcoin & When? Created in 2008 by Satoshi Nakamoto (pseudonym) First implementation launched January 2009 Identity remains unknown

4. What is a Blockchain? Digital ledger of records (blocks) connected in a chain Each block holds transactions Immutable & distributed across many nodes

5. How Does Bitcoin Work? Users send BTC peer-to-peer Transactions broadcast to network Miners validate & add transactions into blocks Blocks chained together → blockchain

6. How Are Bitcoins Created (Mining)? Mining = solving cryptographic puzzles (Proof-of-Work) Miner adds block & gets reward Reward halves ~ every 4 years Max supply capped at 21 million BTC

7. Current Supply & Circulation Total supply cap = 21 million BTC Currently ~19.92 million BTC in circulation Only ~1-2 million BTC remain to be mined

8. Usage & Transactions Buy, sell, store BTC on exchanges Wallets: hot (online) & cold (offline/hardware) Private key signs transaction, public key verifies

9. Public & Private Keys Private key = control your BTC (never share) Public key / address = where others send BTC Digital signatures ensure only owner can spend

10. Why Does Bitcoin Have Value? Scarcity (fixed supply) Demand from users & investors Trust in its network & security Digital gold

11. Risks of Investing in Bitcoin Highly volatile prices Security risks (wallet hacks, phishing) Regulatory changes or bans Scams & fraud

12. Bitcoin vs Traditional Currencies Bitcoin: Decentralized, fixed supply, digital only Fiat: Central bank control, can be printed, physical + digital

13. Pros & Cons Summary Pros: Transparency, fast cross-border payments, no central control, scarcity Cons: Volatility, regulatory uncertainty, scalability, energy use

14. Environmental Impact Mining consumes large electricity Carbon footprint concerns Some miners use renewables

15. Altcoins & Other Cryptos Altcoins = other cryptocurrencies besides Bitcoin Examples: Ethereum, Litecoin, Cardano Differences: consensus, purpose, tokenomics

16. Future Outlook & Discussion Future regulations will matter More institutional adoption likely Layer-2 solutions & scalability upgrades
