29,885,439,722 Bitcoin ($BTC) is a decentralized digital currency created by Satoshi Nakamoto in 2009, operating on blockchain technology. It does not rely on any government or financial institution and is maintained collectively by global nodes through a 'mining' mechanism, ensuring transaction security and transparency. The total supply of Bitcoin is fixed at 21 million coins, giving it scarcity and earning it the title of 'digital gold.' As global interest in crypto assets increases, Bitcoin has gradually evolved from a niche experiment into an important store of value, becoming an alternative solution against inflation and the traditional financial system. Despite significant price volatility, the underlying ideology continues to attract tech enthusiasts, investors, and financial reformers.
