what is Bitcoin?

💡 How Bitcoin Works

1. Decentralized Network

Unlike traditional money — like dollars or euros — Bitcoin isn’t issued by a central bank. Instead, it runs on a peer-to-peer network of computers around the world. These computers work together to verify transactions without needing a centralized authority. IG

2. Blockchain: The Public Ledger

All Bitcoin transactions are recorded in a blockchain — a public ledger that is shared across the whole network. Each set of transactions is grouped into a block, and each new block is linked to the previous one, forming a chain. This makes the history of every bitcoin transparent and difficult to alter. Encyclopedia Britannica

3. Mining and Security

New bitcoins are created through a process called mining. Miners use powerful computers to solve complex mathematical problems. When they solve one, they add a new block of transactions to the blockchain and are rewarded with newly created bitcoins. This process also secures the network. Encyclopedia Britannica

4. No Middlemen

Bitcoin allows anyone to send money to anyone else directly, without needing banks or payment processors. This can make transactions faster and cheaper, especially for international transfers. IG

💰 Why Bitcoin Matters

1. Digital Scarcity

Bitcoin has a fixed supply — only 21 million bitcoins will ever exist. This scarcity is built into the code and cannot be changed. Some people compare this to precious metals like gold. Encyclopedia Britannica

2. Borderless Money

You can send Bitcoin anywhere in the world as long as you have an internet connection. There are no banks to authorize the transaction, and it doesn’t matter where you live. IG

3. Transparency and Security

Because Bitcoin uses cryptography and the blockchain is public, transactions are transparent and tamper-resistant. While personal identities are not openly revealed, the transaction data itself is permanent and viewable by anyone. Encyclopedia Britannica
