$BTC Bitcoin (BTC) is the first and most prominent cryptocurrency, created in 2009 by an individual or group using the pseudonym Satoshi Nakamoto. With blockchain technology, Bitcoin enables direct transactions between individuals without the need for intermediaries, creating a decentralized financial system.

The appeal of Bitcoin comes not only from its profit potential but also from its security and ability to resist inflation. In recent years, Bitcoin has attracted the interest of both individual and institutional investors, with major companies like Tesla and MicroStrategy actively holding BTC.

However, Bitcoin also faces many challenges, including high price volatility, energy consumption issues during mining, and regulatory scrutiny from various countries. Nevertheless, many believe that Bitcoin will continue to prove its value as "digital gold," offering attractive investment opportunities in the future.
