## Bitcoin [Bitcoin](https://ok-ex.io/buy-and-sell/BTC) is the original and most well-known cryptocurrency. It was created in 2009 by an anonymous person or group of people using the pseudonym Satoshi Nakamoto. Bitcoin is a decentralized, peer-to-peer currency that does not require a central authority to manage or oversee transactions. Instead, transactions are verified by a network of nodes, or computers, that work together to validate each transaction. This allows for a trustless system that is not subject to manipulation or control by any single entity. Bitcoin has seen tremendous growth since its inception. It is now the largest cryptocurrency by market capitalization, with a total value of over $100 billion. Despite its volatility, Bitcoin has proven to be a incredibly popular and useful form of digital currency. It is often used as a store of value or investment vehicle, as well as a means of payment for goods and services.
