Bitcoin, the first decentralized cryptocurrency in the world, emerged in 2009 under a pseudonym, Satoshi Nakamoto. Its main innovation lies in blockchain technology, a distributed and immutable ledger that securely and transparently records all transactions. Unlike fiat currencies issued by governments, Bitcoin is not controlled by any central authority, granting it independence and resistance to censorship.
Its value is determined by market supply and demand, fluctuating considerably. It is used for online payments, investments, and as a store of value, often compared to "digital gold" due to its limited supply of 21 million units. Despite its volatility and regulatory concerns, Bitcoin has revolutionized the financial landscape, driving the development of thousands of other cryptocurrencies and laying the groundwork for a more open and global digital economy.
