Bitcoin is a decentralized digital currency that operates without a central authority or banks. It uses peer-to-peer technology to facilitate instant payments. The system works through a public ledger called the blockchain, which records all transactions. Bitcoin was created in 2009 by an unknown person or group using the name Satoshi Nakamoto. It is often referred to as a cryptocurrency because it uses cryptography to secure transactions. Users can buy, sell, and trade Bitcoin on various exchanges. The supply of Bitcoin is limited to 21 million coins, making it a deflationary asset. Mining is the process by which new Bitcoins are created and transactions are verified. Bitcoin has gained popularity as an investment and a means of payment. However, it is known for its price volatility and regulatory challenges. Overall, Bitcoin represents a revolutionary approach to money and finance. |
