Bitcoin (BTC) is the first and most famous decentralized digital currency in the world, launched in 2009 by a person or group using the pseudonym "Satoshi Nakamoto". Bitcoin relies on blockchain technology that allows for transparent and secure recording of all transactions without the need for intermediaries like banks. The number of bitcoins is limited to 21 million units only, making it a rare asset and enhancing its value over time. Bitcoin is used as a means of payment and investment, and is considered today a store of value akin to digital gold. As institutional and investor adoption increases, it has become an important element in the new global financial system.
