Mark Robert Karpelès [1] (born 1985) is the former CEO of bitcoin exchange Mt. Gox. [2] [3] Born in France, he moved to Japan in 2009. [4] [5] Under his leadership, Mt. Gox was the world's largest bitcoin exchange, handling over 70% of all bitcoin transactions at its peak before filing for bankruptcy in 2014. [6] [7] [8] Karpelès was subsequently arrested and convicted of data manipulation related to his role at Mt. Gox.
Born in 1985 in Chenôve, France, Karpelès is the child of geologist Anne-Robert Karpelès. [9] [10] He was raised in Dijon. [9] [11] From 1995 to 2000, he attended Collège Prieuré de Binson in Châtillon-sur-Marne, near Dormans. [2] He then spent one year at Lycée Claude Bernard in Paris before completing his education in 2003 at Lycée Louis Armand in Paris. [2]
In 2009, Karpelès founded Tibanne Co. Ltd., a Japan-based bitcoin related technology provider, where he served as CEO. [12] [13] He was a founding member of the Bitcoin Foundation, created in 2012 with a mission to standardize and promote bitcoin, and served on its board until February 2014. [14] [15]
In 2011, Karpelès acquired the Mt. Gox bitcoin exchange site from programmer Jed McCaleb, with its original owner receiving 12% of the shares of the new company. [16] [17] [18] Under his management, the platform handled the majority of global Bitcoin transactions by 2014. [19] [20] Despite its growth, Mt. Gox faced growing operational, security, and financial challenges, including having $5 million seized from its accounts by the U.S. Department of Homeland Security in 2013 for allegedly lying on bank documents. [21] [22] [23] Mt. Gox then experienced a theft of a significant amount of Bitcoin in 2014. [24] Mt. Gox subsequently filed for bankruptcy, and Karpelès was arrested that year and eventually convicted of data manipulation and falsification of records at Mt. Gox. [25] [26] [27] The collapse of Mt. Gox, and Karpeles's role in it, led Japan to create the first formal regulations for cryptocurrency exchanges and virtual currencies. [28]
After the collapse of Mt. Gox, Karpelès joined London Trust Media, the company behind Freenode and Private Internet Access, as its CTO in April 2018. [29] In 2023, Karpelès was appointed as the minister of technology for Joseon, which operates a blockchain to manage its currency Mun. [30] In 2024, Karpelès announced the launch of EllipX, a new cryptocurrency exchange, which will launch in Poland with Karpelès serving as chief technology officer. [31] [32]
In 2010, at the age of 25, Karpelès was found guilty of fraud during a trial in absentia in France related to his actions on a private server, and he was sentenced to one year in jail. [33] [34] Karpelès had previously been arrested twice in France for charges related to computer fraud, and was convicted and received a suspended sentence of three months as a result of one of the arrests. [35]
In April 2014, after Mt. Gox had filed for bankruptcy, Karpelès was subpoenaed by the United States Department of the Treasury's Financial Crimes Enforcement Network (FinCEN) to testify in Washington, D.C. [36] [37] [38] He responded through his lawyers that he would not be attending the deposition. [39]
On 1 August 2015, Karpelès was arrested by Japanese authorities on suspicion of accessing the Mt. Gox computer system to manipulate account balances. [40] [41] [42] Tokyo prosecutors indicted Karpelès on a series of charges, including embezzlement and aggravated breach of trust, and called for a 10-year prison sentence. [43] Karpelès pleaded not guilty to the charges. [44] On 14 March 2019, the Tokyo District Court found Karpelès guilty of one count of data manipulation for falsifying data to inflate Mt. Gox's holdings by $33.5 million and not guilty of all other charges. [27] He was sentenced to 30 months in prison, suspended for four years, which meant he would serve no time in prison unless he committed additional offenses over the next four years. [45] [46] The court said Karpelès had inflicted "massive harm to the trust of his users" and there was "no excuse" for him to "abuse his status and authority to perform clever criminal acts". [27] Karpelès issued a statement saying he was "happy to be judged not guilty" on the more serious charges and was discussing how to proceed with his lawyers regarding his conviction on the falsifying data charge. [47]
During the 2015 trial of Ross William Ulbricht for operating the Silk Road marketplace, his defense argued that Karpelès, rather than Ulbricht, was the individual behind the pseudonym "Dread Pirate Roberts". [48] Homeland Security Investigations agent Jared Der-Yeghiayan had also suspected Karpelès during a 2012–2013 investigation. [49] Karpelès denied any involvement, and Ulbricht was ultimately convicted. [50] [51]
A cryptocurrency exchange, or a digital currency exchange (DCE), is a business that allows customers to trade cryptocurrencies or digital currencies for other assets, such as conventional fiat money or other digital currencies. Exchanges may accept credit card payments, wire transfers or other forms of payment in exchange for digital currencies or cryptocurrencies.
