What is Bitcoin?
Bitcoin (BTC) is a peer-to-peer digital currency that allows instant transactions without intermediaries like banks. Created by an anonymous person (or group) named Satoshi Nakamoto, Bitcoin introduced blockchain technology—a decentralized ledger that records all transactions securely.
Key Features of Bitcoin:
✅ Decentralized – No government or bank controls Bitcoin.
✅ Limited Supply – Only 21 million Bitcoins will ever exist.
✅ Secure & Transparent – Transactions are verified by miners and recorded on the blockchain.
✅ Borderless – Send and receive Bitcoin anywhere in the world.
How Bitcoin Works
Bitcoin operates on blockchain technology, a public ledger that records every transaction. Here’s a simplified breakdown:
1. Transactions
When you send Bitcoin, your transaction is broadcast to the network. Miners verify it and add it to a block.
2. Mining & Proof-of-Work
Miners use powerful computers to solve complex math problems (Proof-of-Work) to validate transactions. The first miner to solve it gets a block reward (newly minted Bitcoin).
3. Blockchain Security
Once a block is added to the blockchain, it cannot be altered, making Bitcoin highly secure against fraud.
The History of Bitcoin
2008 – The Birth of Bitcoin
Satoshi Nakamoto published the Bitcoin whitepaper, outlining a new electronic cash system.
2009 – Bitcoin Launches
The first Bitcoin block (Genesis Block) was mined, and the first transaction occurred.
2010 – First Real-World Transaction
Laszlo Hanyecz famously bought two pizzas for 10,000 BTC (worth millions today).
2017 – Bitcoin Boom
BTC hit $20,000 for the first time, attracting global attention.
2021 – Institutional Adoption
Major companies like Tesla and MicroStrategy invested billions in Bitcoin, pushing prices to $69,000.
2024 & Beyond
Bitcoin continues to grow with ETF approvals, halvings, and increasing adoption.
Why Bitcoin is Valuable
Bitcoin’s value comes from its scarcity, utility, and decentralization.
1. Digital Gold
Like gold, Bitcoin is scarce (only 21 million will exist), making it a store of value.
2. Hedge Against Inflation
Unlike fiat money, Bitcoin’s supply is fixed, protecting against inflation.
3. Fast & Cheap Transactions
Sending Bitcoin internationally is faster and cheaper than traditional banking.
4. Growing Adoption
From El Salvador making Bitcoin legal tender to companies holding BTC on their balance sheets, adoption is increasing.
How to Buy and Store Bitcoin

You can buy Bitcoin on:
🔹 Exchanges – Binance, Coinbase, Kraken

⚠️ Pro Tip: Always keep your private keys safe—losing them means losing your Bitcoin forever.
