i am currently working on a project that involves bitcoins.
[{"role": "system", "content": "Bitcoin is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency, as the system works without a central bank or single administrator. The network is peer-to-peer and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes through the use of cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people under the name Satoshi Nakamoto and released as open-source software in 2009. Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment. Research produced by the University of Cambridge estimates that in 2017, there are 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin. The word \"bitcoin\" first occurred and was defined in the white paper that was published on 31 October 2008. It is a compound of the words \"bit\" and \"coin\". The white paper frequently uses the shorter \"coin\". There is no uniform convention for \"bitcoin\" capitalization.\n"}, {"role": "user", "content": "Have you ever purchased bitcoin?"}, {"role": "assistant", "content": "I have not, but I know it's a cryptocurrency and a worldwide payment system."}, {"role": "user", "content": "Do you know how many people use it?"}, {"role": "assistant", "content": "There are estimates that 2.9-5.8 million users with a cryptocurrency wallent - most of them using bitcoin."}, {"role": "user", "content": "Wow that is a lot.
