Bitcoin, created in 2009 by Satoshi Nakamoto, is the first decentralized digital currency. Operating on a blockchain, it enables peer-to-peer transactions without intermediaries like banks. Its limited supply and increasing demand have contributed to its soaring value. Decentralization ensures transparency and security, while mining validates transactions. Use cases range from a store of value to facilitating cross-border transactions. However, challenges include volatility, scalability, and regulatory scrutiny. Despite obstacles, Bitcoin's impact on the financial world remains undeniable, shaping the future of money.
