Bitcoin
Bitcoin is a decentralized digital currency that was created in 2009 by an unknown person or group of people using the pseudonym Satoshi Nakamoto. It allows for peer-to-peer transactions over a blockchain network, which is a distributed ledger that records all transactions across a network of computers. Bitcoin operates without a central authority or intermediary, making it a form of currency that is not controlled by any government or financial institution. Users can send and receive Bitcoin anonymously, and transactions are secured using cryptographic techniques. The total supply of Bitcoin is capped at 21 million coins, making it a deflationary currency. Bitcoin can be used for various purposes, including online purchases, investment, and remittances, and it has gained significant attention and popularity as a financial asset and a store of value. Its price is highly volatile, influenced by factors such as market demand, investor sentiment, and regulatory developments.
