Bitcoin is the world’s first and most famous cryptocurrency. It introduced a completely new financial system where money can exist without banks, governments, or central control. Instead, it runs on a decentralized network called blockchain.
It is often called “digital gold” because of its limited supply and long-term value potential.
📌 What is Bitcoin?
Bitcoin is a decentralized digital currency that allows people to send and receive money online directly, without intermediaries.
It was created in 2009 by:
Satoshi Nakamoto (anonymous creator)
Bitcoin operates on blockchain technology, which is a public digital ledger that records every transaction.
🔗 How Bitcoin Works
Bitcoin runs on a global network of computers that validate transactions.
Core idea:
\text{Blockchain} = \text{Distributed Ledger of All Bitcoin Transactions}
Each transaction is:
Verified by miners
Added to a block
Stored permanently on the blockchain
⛏️ Bitcoin Mining
Mining is the process that secures the Bitcoin network.
Miners:
Solve complex mathematical problems
Verify transactions
Add new blocks to the blockchain
Earn Bitcoin rewards
This system keeps Bitcoin secure and decentralized.
💰 Why Bitcoin is Valuable
1. Limited Supply
Only 21 million Bitcoins will ever exist.
2. Decentralization
No central authority controls it.
3. Global Use
Can be sent anywhere in the world.
4. Store of Value
Seen as protection against inflation.
📊 Bitcoin Supply Limit
\text{Total Bitcoin Supply} = 21,000,000\ \text{BTC (Maximum Limit)}}
This scarcity is one of the main reasons Bitcoin is compared to gold.
