$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency in the world, launched in 2009 by a pseudonymous entity known as Satoshi Nakamoto. It operates on a decentralized network called blockchain, which enables secure and transparent transactions without the need for intermediaries like banks or governments.

In 2025, Bitcoin continues to be used both as a means of payment and, especially, as a store of value, often referred to as "digital gold." Its adoption is on the rise: financial institutions, companies, and even some governments are including it in their portfolios or payment systems. However, it remains subject to price volatility, variable regulations, and debates regarding the environmental impact of mining.
