Mark Marie Robert Karpelès
June 1, 1985
Mark Marie Robert Karpelès (born June 1, 1985), also sometimes known by his online alias MagicalTux, is the former CEO of bitcoin exchange Mt. Gox. Born in France, he moved to Japan in 2009.
Early life and education
Karpelès was born in 1985 in Chenôve, France, the child of Anne-Robert Karpelès, a geologist. He was raised in Dijon. Between 1995 and 2000 he was educated at Collège Prieuré de Binson in Châtillon-sur-Marne, near Dormans. He then spent one year at Lycée Claude Bernard in Paris before completing his education in 2003 at Lycée Louis Armand in Paris.
In 2009, Karpelès founded Tibanne Co. Ltd., a Japan-based bitcoin related technology provider. He is CEO. 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.
Karpelès acquired the Mt. Gox Bitcoin exchange site from programmer Jed McCaleb in 2011 which was later incorporated in Tokyo, with its original owner receiving 12% shares of the new company. Mt. Gox filed for bankruptcy in Japan on February 28, 2014, and for Chapter 15, Title 11, United States Code bankruptcy in the United States (Texas) in March 2014.
Karpelès was subpoenaed by the United States Department of the Treasury's Financial Crimes Enforcement Network to appear in Washington, D.C. to provide testimony on April 18, 2014. In a court filing by Mt. Gox lawyers, Karpelès responded that he did not have a lawyer for this matter and therefore declined to appear. He sought to appear in D.C. to testify on May 5, 2014.
According to a joint report by Cyrus Farivar of Ars Technica and Pierre Alonso of Le Monde, Karpelès was found guilty of fraud when he was tried in absentia in France in 2010. He also admitted to having "pirated" a server to French authorities. He was sentenced to a suspended year in jail.
The lawyers for Ross William Ulbricht, defending him at his trial for operating the undercover Silk Road marketplace, claimed in 2015 that the pseudonymous "Dread Pirate Roberts" behind Silk Road was not him but Karpelès. The Department of Homeland Security had also suspected as such in 2012-2013. Karpelès publicly denied the claim on Twitter and Ulbricht was eventually found guilty.
Arrest and prosecution
Karpelès was arrested on August 1, 2015, by Japanese police on suspicion of having accessed the exchange's computer system to falsify data on its outstanding balance; he was re-arrested and allegedly charged with embezzlement.
Karpelès was released on bail in July 2016, but was required to remain in Japan.
On July 10, 2017, he pled "not guilty" to embezzlement and data manipulation charges.
On March 14, 2019, the Tokyo District Court found Karpelès guilty of falsifying data to inflate Mt. Gox’s holdings by $33.5 million, for which he was sentenced to 30 months in prison, suspended for four years, meaning he will serve no time unless he commits additional offenses over the next four years. The Court acquitted Karpelès on a number of other charges, including embezzlement and aggravated breach of trust, based on its belief that Karpelès had acted without ill intent. Nonetheless, the verdict 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.” 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.
Mt. Gox's bankruptcy proceedings will repay creditors in Japanese yen at a price around 483 US dollars per bitcoin (total of 45.6 billion Japanese yen or 400 million US dollars) and it has been reported that this will leave Karpelès, after creditors are repaid, with the bulk of the wealth left over from the difference. Based on the market price at the beginning of 2018 (around $15,000 per bitcoin), the difference is significant, and would leave Karpelès with bitcoins valued at more than 1.4 billion US dollars.
In June 2018, The Tokyo District court approved a petition by creditors to begin civil rehabilitation proceedings in lieu of bankruptcy. As these proceedings are more flexible, creditors expected that they would be compensated based on the current value of their lost coins. On August 23, 2018, creditors were able to begin filing new claims under the civil rehabilitation proceedings. Under the current[may be outdated] schedule, compensation is expected to be distributed in late 2019.[needs update]
