=== Bitcoin ===
Andresen was the lead developer for a part of the bitcoin digital currency project, working to create a secure, stable "cash for the Internet." Andresen discovered bitcoin in 2010, considering its design to be brilliant. Soon after he created a website named The Bitcoin Faucet which gave away bitcoin. In April 2011, Forbes quoted Andresen as saying, "Bitcoin is designed to bring us back to a decentralized currency of the people," and "this is like better gold than gold." After joining the developers contributing to Bitcoin along with Satoshi Nakamoto, he went on to become lead developer of the client software for the bitcoin network. In June 2011, he attended an "emerging technologies conference for the US intelligence community" held by In-Q-Tel to present on Bitcoin. He stepped back as lead maintainer in 2014.Andresen also created ClearCoin, an escrow-type of service, which was closed on about June 23, 2011. After several years working on the software, Andresen left the role of lead developer of bitcoin to work on the strategic development of its technology. He conceived of the Bitcoin Foundation which became reality in September 2012.In May 2016 Andresen stated that the Australian programmer and entrepreneur Craig Wright was Nakamoto, but later expressed regret getting involved in the "'who was Satoshi' game", and stated "it was a mistake to trust Craig Wright."Andresen has not contributed to Bitcoin since February 2016. He had become critical of the failure of bitcoin developers to increase network capacity, and helped put together Bitcoin XT as alternative software. His commit access to Bitcoin Core on GitHub was revoked in May 2016 after stating Wright was Satoshi Nakamoto. In November 2017, Andresen expressed support for rival currency Bitcoin Cash, stating "Bitcoin Cash is what I started working on in 2010".
