<human>:  How do I explain Bitcoin to someone who isn't familiar with cryptocurrency?
<bot>: Bitcoin is an innovative digital currency that was created in 2009 by a mysterious individual or group known as "Satoshi Nakamoto." It is the world's first decentralized cryptocurrency, meaning that it is not controlled by any government or central bank and is instead powered by a network of computers around the globe. Bitcoin can be used to buy and sell goods and services, and there are many exchanges available for users to securely convert their money into and out of Bitcoin. It is also a potentially valuable asset as its price is determined by the forces of supply and demand.
