Bitcoin is the first and most well-known cryptocurrency. It was created in 2009 by an unknown person or group of people using the pseudonym Satoshi Nakamoto. Bitcoin operates on a decentralized network called blockchain, which is a distributed ledger that records all transactions.

    One of the key features of Bitcoin is its limited supply. There will only ever be 21 million bitcoins in existence, making it a deflationary asset. This scarcity has contributed to its value over time.

    Bitcoin transactions are verified by network nodes through cryptography and recorded in a public ledger called a blockchain. This ensures transparency and security in the system.

    Despite its volatility, Bitcoin has gained mainstream adoption and has become a popular investment asset. Its price is influenced by various factors including market demand, adoption rates, regulatory developments, and macroeconomic trends.
