Bitcoin, created in 2009 by Satoshi Nakamoto, is the world's first decentralized cryptocurrency. It operates on a blockchain network, which ensures security and transparency without intermediaries like banks. With a supply limited to 21 million units, Bitcoin is scarce like gold, making it a deflationary asset. Its appreciation attracts investors, but volatility requires caution. Companies and countries have already adopted BTC as a store of value or means of payment. In addition to revolutionizing the financial system, Bitcoin represents economic freedom, resistance to censorship, and global financial inclusion. However, challenges such as regulation and energy consumption still need to be balanced for its mass adoption.$BTC
