$BTC Bitcoin ($BTC) is the first decentralized cryptocurrency, created in 2009. Its importance lies in the fact that it enables secure transactions without banking intermediaries, offering freedom of global payments with low fees. It acts as a "digital gold" or store of value, especially in volatile economies, protecting against inflation. Although volatile, its deflationary nature and blockchain technology position it as a disruptor of the traditional financial system, facilitating financial inclusion and innovation.
