$BTC is the first and most important cryptocurrency, created in 2008 by Satoshi Nakamoto. It operates on a decentralized blockchain, allowing for secure transactions without the need for intermediaries. Its supply is limited to 21 million coins, which reinforces its deflationary nature.

Currently, BTC has a market capitalization of approximately $2.10 trillion, with a circulating supply of 19.87 million coins. Its price hovers around $109,578, although it constantly varies according to supply and demand in global markets.
