Bitcoin is a decentralized digital currency created in 2009. It runs without central banks, using blockchain technology to record transactions securely and transparently. It is the first and most valuable cryptocurrency in the world.

Is Bitcoin the same as other cryptocurrencies?

No. Bitcoin was the first cryptocurrency and remains the largest and most secure. Other cryptocurrencies (altcoins) serve different purposes — Ethereum for smart contracts, stablecoins like USDT for price stability.

Q: How does Bitcoin work?

Bitcoin works through the blockchain — a digital ledger distributed across thousands of computers worldwide. Every transaction is verified by miners and permanently recorded. No intermediary like a bank is needed.

Q: Why does Bitcoin have value?

Bitcoin has value due to scarcity (only 21 million will ever exist), decentralization (no single authority controls it), growing adoption, and security (the blockchain has never been hacked in over 15 years).

Bitcoin explained simply

Imagine you want to send money to a family member in another city. Normally you'd go through a bank, pay fees, and wait. The bank controls the process.

Bitcoin is different. It's digital money you can send directly to anyone in the world, in minutes, without needing a bank. No government, bank or company controls Bitcoin — it's run by thousands of computers spread across the globe.

Who created Bitcoin?

Bitcoin was created in 2009 by an anonymous person (or group) known as Satoshi Nakamoto. They published a technical paper explaining how it would work, then disappeared. To this day, nobody knows who Satoshi really is — and that's by design: Bitcoin belongs to everyone, not a single company or founder.

How does Bitcoin work? (Blockchain)

Bitcoin runs on blockchain technology — think of it as a giant ledger that records every Bitcoin transaction ever made.

Key properties of the blockchain

Decentralized: Copied across thousands of computers worldwide — no single server to attack or control.
Transparent: Anyone can view all transactions.
Immutable: Once recorded, a transaction cannot be altered or deleted.
Secure: Uses advanced cryptography — mathematically near-impossible to counterfeit.

Why does Bitcoin have value?

Property	Why it matters
Scarcity	Only 21 million BTC will ever exist — no government can print more, unlike fiat currencies.
Durability	Bitcoin doesn't degrade — it exists digitally as long as the internet does.
Divisibility	1 BTC splits into 100 million units (satoshis) — you can buy a tiny fraction.
Portability	Carry millions worth of Bitcoin on your phone — try that with gold.

Is Bitcoin safe?

The Bitcoin network itself is extremely secure. In over 15 years, it has never been hacked. However, you can still lose Bitcoin if you lose your password/seed phrase, fall for scams, use untrustworthy platforms, or click phishing links. Security depends mostly on you. 👉 See our wallet security guide
