Mtgox or Mt. Gox was one of the first websites where users could take part in fiat-to-bitcoin exchange (and vice versa). In 2014, Mt. Gox was shut down after about 850,000 bitcoin was declared lost or stolen. Mt. Gox was created in 2006 by Jed McCaleb who named it after Magic The Gathering Online Exchange where users could use the cards like stocks. Jed later sold Mt. Gox to Mark Karpelès in 2011.
