Bitcoin (BTC) is a decentralized digital currency created in 2009 by a person (or group) under the pseudonym Satoshi Nakamoto. It was the first cryptocurrency and is based on a technology called blockchain, which functions as a public, immutable, and distributed record of all transactions made on the network.

Key features of Bitcoin:

Decentralization: It is not controlled by governments, banks, or financial institutions.

Transparency: All transactions are publicly recorded on the blockchain.

Limited supply: The total number of bitcoins that can be issued is 21 million, making it deflationary.

Security: It uses advanced cryptography to ensure the integrity and security of transactions.

Pseudonymity: Transactions are public, but users are not directly identified.

Common uses:

As a store of value (often referred to as "digital gold").

For international transfers without intermediaries.

As a means of payment, although its use in this function is still limited compared to traditional currencies.
