What is Bitcoin?

At its core, Bitcoin is a decentralized digital currency. "Digital" means it only exists electronically. "Decentralized" is the key innovation: unlike traditional money controlled by banks and governments, Bitcoin is run by a global, open network of computers, making it transparent and resistant to censorship.

Bitcoin combines digital scarcity with a decentralized network.

Created in 2009 by the anonymous figure known as Satoshi Nakamoto, it allows for secure and direct peer-to-peer payments to be sent anywhere in the world without needing a financial intermediary like a bank. This revolutionary peer-to-peer system is the foundation of its value and utility.

How Does it Work?

Bitcoin transactions are recorded on a public digital ledger called the blockchain. Imagine a giant, shared digital checkbook that everyone can see but no one can alter after the fact. Every transaction is a new entry in this globally distributed checkbook.

Visualizing the blockchain: each link in the chain secures the one before it, creating a permanent public ledger.

These transactions are grouped into "blocks." Once a block is full, it's cryptographically linked to the previous one, forming a "chain." This process, called mining, is performed by powerful computers that compete to solve complex mathematical puzzles. By solving the puzzle, miners validate transactions, add the new block to the chain, and are rewarded with newly created bitcoin. This process secures the network and is what you see happening in real-time in the data feeds to the right.

Why is it Valuable?

Bitcoin's value is derived from a unique combination of technological properties, economic principles, and the collective belief of its users.

  • Scarcity: There will only ever be 21 million bitcoins created. This fixed supply, codified in the protocol, is a stark contrast to traditional fiat currencies which can be printed at will. This makes Bitcoin inherently resistant to inflation.
  • Utility: It serves as a global, permissionless payment network. It can be used to send any amount of value across the globe quickly and cheaply, and increasingly acts as a long-term "store of value"—often called "digital gold"—outside the traditional financial system.
  • Decentralization: No single person, company, or government controls Bitcoin. This provides a robust defense against institutional failure, censorship, or manipulation, offering a hedge against geopolitical instability.
  • Security: The blockchain is secured by an immense amount of computing power (the hash rate). Its cryptographic foundation makes it one of the most secure computer networks ever created.

The metrics on the right reflect the network's real-time health, security, and economic scale.

Frequently Asked Questions

What is a Bitcoin wallet?

A Bitcoin wallet is a digital wallet that stores your public and private keys. Your public key is like a bank account number for receiving funds, while the private key, which must be kept secret, authorizes spending. Wallets can be software on your phone or computer, or secure hardware devices.

How do I buy Bitcoin?

You can buy Bitcoin on crypto exchanges like Coinbase, Binance, or Kraken. You’ll need to verify your identity, link a bank account or card, and then you can purchase any amount you wish.

Can I buy a fraction of a Bitcoin?

Yes, absolutely. Each bitcoin is divisible into 100 million smaller units called 'satoshis'. This allows you to buy very small amounts, like $10 or $20 worth, making it accessible to everyone regardless of the high price of a full coin.

Is Bitcoin legal?

In most countries, yes. The UK, US, and much of Europe allow it. However, some countries have placed strict bans or restrictions on its use. Always check your local regulations.

Is Bitcoin mining still profitable?

For most individuals, no. Today, mining is dominated by large-scale operations with specialized, powerful hardware (called ASICs) and access to cheap electricity. The combination of high difficulty and massive energy costs makes it extremely difficult for hobbyists to turn a profit.

Is Bitcoin Anonymous?

Not entirely. It's pseudonymous. While your real name isn't attached, all transactions are public. If your address is ever linked to you, your history can be traced.
