What is Bitcoin?
Introduction:

Features:
- Decentralization: Bitcoin is not controlled by any bank or government. Transactions are recorded on a distributed ledger (blockchain) maintained by computers on the network.
- Anonymity: Bitcoin transaction addresses are not associated with personally identifiable information, which provides anonymity.
- Security: Bitcoin transactions are protected by encryption technology, making them difficult to counterfeit or double-spend.
- Limited Supply: The total supply of Bitcoin is limited to 21 million coins to prevent inflation.
- Transparency: All Bitcoin transactions are recorded on the public blockchain and can be viewed at any time.
How it works:
Bitcoin operates through a peer-to-peer transaction network. When one person sends Bitcoin to another person, a record of the transaction is broadcast to the network and added to the blockchain. The transaction is verified by computers in the network, called miners, before it can be completed.

- Buy goods and services online
