What is Bitcoin?
A peer-to-peer electronic cash system.
— Satoshi Nakamoto, 2008
Bitcoin is digital money that works without banks.
Imagine cash, but for the internet. You can send it to anyone, anywhere, at any time — without asking permission from a bank, government, or company.
It runs on a global network of computers that anyone can join. No single person or organization controls it. The rules are enforced by math and code, not by trust in institutions.
Key Properties
Decentralized
No company, government, or individual controls Bitcoin. It runs on a global network of computers following the same rules.
Scarce
Only 21 million bitcoin will ever exist. This is enforced by code, not by trust in any institution.
Open
Anyone can use Bitcoin. No approval needed. No account to open. No borders.
Permissionless
You don't need permission to send or receive bitcoin. Your transactions cannot be censored.
Verifiable
Anyone can verify the total supply and all transactions. Everything is transparent and auditable.
Immutable
Once confirmed, transactions cannot be reversed or altered. The history is permanent.
Why Does It Matter?
Financial Freedom
Bitcoin gives anyone, anywhere access to a global monetary network. No bank account required. No credit check. No discrimination.
Sound Money
Unlike government currencies that can be printed endlessly, Bitcoin's supply is mathematically fixed. This makes it a reliable store of value over time.
Sovereignty
You truly own your bitcoin. No one can freeze your account, block your transactions, or confiscate your funds without your private keys.
