What Is Bitcoin?
Bitcoin is a decentralized cryptocurrency existing solely in digital form.
Bitcoin (BTC or XBT) is a decentralized cryptocurrency. Unlike traditional currencies regulated by central banks (e.g., the Brazilian Central Bank), Bitcoin operates without government or institutional oversight.
As a virtual currency, Bitcoin has no physical form.
All issuance—called mining—occurs online via powerful computers.
In 2017, Bitcoin entered mainstream finance, trading on the Chicago Mercantile Exchange. Today, users can mine or acquire Bitcoin through specialized exchanges.
Notably, Bitcoin’s protocol caps supply at 21 million units, with the last coin expected in 2140.
Who Created Bitcoin?
Introduced in 2008 via The Cryptography Mailing list, Bitcoin was created by Satoshi Nakamoto—a pseudonymous programmer (or group). Nakamoto’s true identity remains unknown.
The smallest Bitcoin fraction (0.00000001 BTC) is called a Satoshi, honoring its creator.
How Does Bitcoin Work?
Bitcoin functions differently from traditional investments:
- Decentralized Trading: Users buy/sell directly without intermediaries.
- Public Ledger: Transactions are recorded on the blockchain, ensuring transparency.
- Mining: Users solve complex math problems to earn new Bitcoins.
What Is Blockchain?
Blockchain—a chain of blocks—is Bitcoin’s underlying technology.
This immutable ledger:
- Records all transactions permanently.
- Links blocks chronologically via unique codes (hashes).
- Enhances security, transparency, and efficiency.
