Bitcoin is a type of digital currency that was created in 2009 by an anonymous individual (or individuals) using the pseudonym Satoshi Nakamoto. Bitcoin is decentralized, meaning it is not controlled by any government or central bank. Instead, it is powered by a distributed network of computers across the world that record every transaction made with Bitcoin. Bitcoin is also borderless, meaning it can be sent and received anywhere in the world at any time, with near-instant settlement. Bitcoin can also be used to purchase goods and services, as well as being traded for other currencies.
