$BTC

$BTC is the shorthand code for Bitcoin, the first and most famous decentralized digital currency launched in 2009 by a person or group using the pseudonym "Satoshi Nakamoto". Bitcoin is a digital asset that relies on blockchain technology to document transactions securely and transparently without the need for a central intermediary like banks.

$BTC is used as an investment tool, a means of payment in some places, and a digital refuge from inflation. It is considered a key indicator of the state of the digital market, as its movement affects other cryptocurrencies.
