Bitcoin (BTC) is a decentralized digital currency created in 2009 by an unknown person known as 'Satoshi Nakamoto.' It relies on blockchain technology, which is a public ledger that records all transactions in a transparent and secure manner. It is not controlled by any government or central bank, making it attractive to investors seeking financial freedom. Bitcoin is produced through a process known as mining, which requires a significant amount of computing power. Despite its large price volatility, Bitcoin remains one of the most prominent digital assets in the world and is considered the beginning of an era of digital currencies and decentralized economy.
