$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by an anonymous person or group using the pseudonym Satoshi Nakamoto. It was designed to be a decentralized digital currency that operates without the need for a central authority like a bank or government. Instead, it uses blockchain technology—a public, distributed ledger that records all transactions transparently and securely.

Bitcoin allows people to send and receive money over the internet directly, without relying on intermediaries. It uses a proof-of-work system where miners solve complex mathematical problems to validate transactions and secure the network. In return, miners are rewarded with newly minted bitcoins.

One of the key features of Bitcoin is its limited supply: only 21 million bitcoins will ever exist, which gives it a deflationary nature and has led some people to compare it to digital gold. Over the years, Bitcoin has gained widespread attention as both a form of payment and an investment asset. Its price can be highly volatile, often influenced by market demand, regulation, and global events. Despite these fluctuations, Bitcoin continues to play a significant role in the evolution of digital finance.
