$BTC O **Bitcoin (\$BTC)** is the first and most well-known cryptocurrency in the world, created by an individual or group under the pseudonym of **Satoshi Nakamoto** in 2009. BTC emerged with the aim of being a decentralized alternative to the traditional financial system, allowing peer-to-peer transactions without the need for intermediaries such as banks or governments. Its operation is based on a technology called **blockchain**, which ensures security, transparency, and immutability of records.

With a supply limited to **21 million units**, Bitcoin is considered by many investors as a kind of **"digital gold"**, being used both as a store of value and as protection against inflation and global economic instability. BTC operates on a **proof of work (Proof of Work - PoW)** system, which means that new coins are mined through a computationally intensive process that also helps keep the network secure.

Over the years, Bitcoin has gone through various phases: from technological curiosity to global financial asset, being accepted by companies, investment funds, and even governments. BTC price movements directly impact the entire crypto market, being closely monitored by traders, analysts, and institutional investors. In 2025, debates about institutional adoption, regulations, and its acceptance as a national store of value continue to shape the future of Bitcoin in the global financial landscape.
