Bitcoin is a digital cryptocurrency that was launched in 2009 by an individual or group of individuals under the pseudonym "Satoshi Nakamoto". Bitcoin is considered the first decentralized digital currency, operating without an intermediary or central authority such as banks or governments. It relies on "blockchain" technology, which is a public open ledger that records all transactions securely and transparently.

Bitcoin is mined through a process known as "mining", which requires a significant amount of computational power to solve complex mathematical equations. Over time, the mining process has become more difficult and energy-intensive.

One of the most important features of Bitcoin is its limited supply, with a maximum production cap of 21 million units, which enhances its relative value over time. Bitcoin has experienced sharp price fluctuations, making it a point of interest for investors and speculators, as well as a topic of debate among its supporters and detractors.

Despite the opportunities it offers, Bitcoin faces challenges related to regulatory oversight, its environmental impact, and the possibility of being used for illegal activities. Nevertheless, Bitcoin remains a symbol of technological advancement and innovation in the world of finance and digital economy.
