Bitcoin ($BTC ) is the first and most well-known cryptocurrency, created in 2009 by Satoshi Nakamoto (a pseudonym). It represents a decentralized digital currency that operates without a central authority, such as a bank or government. Transactions are verified and recorded in a distributed public ledger known as the blockchain. The fundamental principle of Bitcoin lies in its limited supply of 21 million coins, which gives it a deflationary character and contributes to its perceived value as 'digital gold.' $BTC is a revolutionary innovation that has influenced the entire financial world and led to the creation of thousands of other cryptocurrencies.

Its value is determined by supply and demand in the market, being heavily influenced by investor sentiment, macroeconomic events, regulatory news, and technological developments. Bitcoin has become an investment asset, a means of payment for some goods and services, and a benchmark for the entire cryptocurrency market. Many traders and investors consider it a store of value and a hedge against inflation. Due to its pioneering role and market dominance, $BTC is often the first point of contact for new participants in the crypto world, and its price movements have a significant impact on the entire digital asset sector.
