Bitcoin is a form of digital money. You can send it directly to anyone in the world, at any time, without needing a bank or a payment company in the middle. It was created in 2009 and is the first and best-known cryptocurrency.
How does Bitcoin work?
Bitcoin runs on a network of thousands of computers instead of one central company. Every transaction is recorded on a shared public ledger called the blockchain. Because thousands of copies of this ledger exist, no single person can secretly change it — which is what makes Bitcoin hard to cheat.
New coins enter circulation through mining, where computers compete to confirm transactions and are rewarded with Bitcoin. The total supply is capped at 21 million coins, which is a big reason people compare it to "digital gold."
Why does Bitcoin have value?
Bitcoin has value for a few simple reasons:
- Scarcity — only 21 million will ever exist.
- Decentralization — no government or bank controls it.
- Portability — you can move any amount across the world in minutes.
- Demand — more people and companies hold it every year.
How do you buy Bitcoin?
The simplest way is through a crypto exchange. You create an account, add funds with a card or bank transfer, and buy Bitcoin in a few taps. Look for an exchange with low fees, strong security, and beginner-friendly tools.
What are the risks?
Bitcoin's price is volatile — it can rise or fall sharply. Only invest money you can afford to lose, keep your account secure with two-factor authentication, and never share your passwords or recovery phrases. This is general information, not financial advice.
