Bitcoin (BTC) is the first decentralized digital currency, created in 2009 by an anonymous developer or group known as Satoshi Nakamoto. It is built on blockchain technology, which is a public ledger that records all transactions. A key feature of Bitcoin is its limited supply – the maximum number of coins that will ever exist is 21 million. This limited supply makes it a digital alternative to precious metals like gold.
Bitcoin has become popular due to its decentralization, meaning it is not controlled by any government or bank. Users can send BTC directly to each other without the need for an intermediary. However, the volatility of its price sparks debate – some see it as a revolutionary payment system, while others view it as a risky investment. Despite this, Bitcoin remains a symbol of innovation in finance and technology.
