What Is Bitcoin & Why Does It Matter?
Bitcoin is digital money designed to operate without central banks or governments. Imagine cash for the internet—but decentralized, secure, and globally accessible. Created in 2009 by the pseudonymous Satoshi Nakamoto, Bitcoin introduced the world to blockchain technology, revolutionizing finance and sparking the cryptocurrency movement.
Key Features of Bitcoin
- Decentralized: No single entity controls Bitcoin; it’s maintained by a global network of computers.
- Transparent & Immutable: All transactions are recorded on a public ledger (blockchain) that can’t be altered.
- Limited Supply: Only 21 million Bitcoins will ever exist, creating scarcity akin to digital gold.
- Divisible: Each Bitcoin can be split into 100 million satoshis, enabling microtransactions.
- Pseudonymous: Wallet addresses are visible, but identities aren’t directly linked.

How Bitcoin Works
The Blockchain: Bitcoin’s Backbone
The blockchain is a public ledger where every transaction is verified by "miners" (computers solving cryptographic puzzles). This process ensures:
- Security: Fraudulent transactions are nearly impossible.
- Trustlessness: No need for intermediaries like banks.
- Global Accessibility: Anyone with internet can participate.
Sending Bitcoin
- Initiate: Use a digital wallet to send Bitcoin.
- Broadcast: The transaction is shared with the network.
- Verify: Miners validate the transaction.
- Confirm: It’s added to the blockchain—forever.
Why Bitcoin Was Created
Born after the 2008 financial crisis, Bitcoin offered an alternative to traditional banking—a peer-to-peer electronic cash system free from central control. Its goals:
- Financial Sovereignty: Users control their funds.
- Inflation Resistance: Fixed supply prevents devaluation.
- Borderless Payments: Send value anywhere, anytime.
