$BTC Bitcoin (BTC) is the first decentralized cryptocurrency in the world. It was invented in 2008 by an unknown person or group using the pseudonym "Satoshi Nakamoto", and began to be used in 2009.

Here is a brief overview of Bitcoin:

* Digital and decentralized currency: Bitcoin is not controlled by any government or central bank, and transactions occur directly between users (peer-to-peer) without the need for an intermediary.

* Blockchain technology: Bitcoin relies on blockchain technology to record all transactions in a public, distributed, and secure ledger, ensuring transparency and preventing manipulation.

* Mining: The Bitcoin network is secured and new transactions are added to the blockchain through a process called "mining", where miners use computational power to solve complex mathematical problems and are rewarded with new bitcoins.

* Scarcity: Bitcoin is designed to have a limited supply, with no more than 21 million bitcoins to ever be issued. This makes it a scarce asset.
