Bitcoin (BTC) is the first decentralized digital currency launched in 2009 by a person or group known as 'Satoshi Nakamoto'. Bitcoin relies on blockchain technology, which is a transparent public ledger that records all transactions without the need for an intermediary like banks. The number of bitcoins is limited to only 21 million coins, making it resistant to inflation and attractive to investors as a store of value like gold. Bitcoin is used for international transfers quickly and at a lower cost compared to traditional systems. It has also become accepted in many stores and businesses. In recent years, it has experienced sharp price fluctuations, making it a major focus of interest for investors and economic analysts.
