Introduction to Bitcoin (BTC)

Bitcoin (BTC), introduced in 2009 by an anonymous entity under the pseudonym Satoshi Nakamoto, is the world's first cryptocurrency. It is based on a revolutionary technology called blockchain, a secure, decentralized digital ledger that records all transactions in a transparent and immutable way. This innovation has revolutionized the world of finance by offering an alternative to traditional centralized monetary systems.

How Bitcoin Works

Bitcoin operates without the intervention of a central authority, such as a bank or government. Transactions are validated by a network of computers called "miners," who solve complex mathematical problems to add new blocks to the blockchain. In exchange for their work, miners receive rewards in the form of newly created bitcoins. This process is limited by a cap of 21 million BTC, ensuring a scarcity that contributes to its value.

Advantages of Bitcoin

1. Decentralization: Unlike fiat currencies, Bitcoin is not controlled by a central institution, reducing the risk of manipulation or abusive inflation.

2. Security: Bitcoin transactions use cryptography to ensure their security, and the decentralized nature of the blockchain makes it difficult to hack.

3. Accessibility: Bitcoin is accessible to everyone, without geographical restrictions, providing a financial solution for people excluded from the banking system.

4. Transparency: All transactions are publicly visible on the blockchain, ensuring complete transparency.
