What Is Bitcoin?
Bitcoin (BTC) is a decentralized digital currency created in 2009 by an unknown person or group using the pseudonym
Satoshi Nakamoto. Unlike traditional money issued by governments (fiat currency), Bitcoin is:
Decentralized – no central bank or authority controls it
Digital – no physical coins or bills exist
Limited – only 21 million bitcoins will ever existBitcoin operates on a technology called blockchain, which is a transparent public ledger that records every transaction. This eliminates the need for banks or third-party intermediaries.
How Bitcoin Works:
The Blockchain Explained
The Bitcoin blockchain is a decentralized, peer-to-peer network that runs on thousands of computers worldwide (called “nodes”).
Here’s how it works:
1. Transactions are made between users.
2. These transactions are grouped into blocks.
3. Each block is verified through a process called mining.
4. Once verified, the block is added to the blockchain, creating a permanent record.
Miners use powerful computers to solve complex math problems. When they successfully add a block, they are rewarded with new bitcoins. This process is known as the Proof of Work system.
Why Is Bitcoin Valuable?
Bitcoin derives its value from several key factors:
1. ScarcityOnly 21 million bitcoins will ever be mined. This limited supply creates a scarcity similar to gold, which many believe makes it a solid store of value.
2. DecentralizationNo central authority can manipulate Bitcoin’s supply, unlike fiat currencies, which governments can print at will.
3. SecurityBitcoin transactions are nearly impossible to forge or reverse thanks to cryptographic technology and a vast, distributed network.
4. Global AcceptanceMajor companies like Microsoft, PayPal, and even Starbucks accept Bitcoin. In countries with unstable currencies, Bitcoin is often used as an alternative to protect wealth.
