$BTC

Bitcoin (BTC) is the first and most well-known cryptocurrency in the world, introduced in 2009 by the pseudonymous creator Satoshi Nakamoto. Designed as a decentralized digital currency, Bitcoin operates without a central authority like a bank or government. Instead, it relies on blockchain technology, a tamper-proof public ledger that records all transactions through a global network of computers.

Bitcoin's fixed supply of 21 million coins makes it deflationary by nature, often earning the nickname "digital gold." It can be used for person-to-person transactions, international payments, or held as a store of value. Transactions are verified by miners who solve complex mathematical problems, securing the network and earning new BTC as a reward, a process known as proof of work.

Over the years, Bitcoin has evolved from a niche internet experiment to a major financial asset. It has attracted institutional investors, sparked regulatory debates, and influenced the development of thousands of other cryptocurrencies. Despite its volatility, many see Bitcoin as a hedge against inflation and a tool for financial sovereignty.

With increasing mainstream acceptance, integration into payment systems, and growing adoption by businesses and even governments, Bitcoin continues to shape the future of global finance and challenge traditional monetary systems.
