$BTC Bitcoin (BTC) is the first cryptocurrency created in 2009 by an individual or group under the pseudonym Satoshi Nakamoto. It is based on a technology called blockchain, which ensures the transparency and security of transactions without a central authority. As a store of value, BTC is often compared to digital gold. Its supply is limited to 21 million units, which enhances its scarcity. Despite its volatility, it attracts investors, institutions, and governments. Bitcoin plays a central role in the evolution of digital assets and in current discussions about the regulation of the sector in the United States.
