Mt. Gox CEO Karpelès Reveals Details of 2014 Collapse and Japanese Detention

In late 2025, Mark Karpelès, ex CEO of Mt. Gox, lives a quieter life in Japan, building a VPN and an AI automation platform. As Chief Protocol Officer at vp.net-a VPN that uses Intel’s SGX technology to let users verify exactly what code runs on servers-he works alongside Roger Ver and Andrew Lee, the founder of Private Internet Access. “It’s the only VPN that you can trust basically. You don’t need to trust it, actually, you can verify”. At shells.com, his personal cloud computing platform, he’s quietly developing an unreleased AI agent system that hands artificial intelligence full control over a virtual machine: installing software, managing emails, and even handling purchases with a planned credit card integration. “What I’m doing with shells is giving AI a whole computer and free rein on the computer”, a brilliant idea, really. AI agents on steroids. The contrast with his past could not be starker. Fifteen years ago, Karpelès was the reluctant king of Bitcoin’s trading world, running Mt. Gox at a time when the exchange processed the vast majority of global bitcoin trades. His journey began innocently enough in 2010. Operating a web hosting company called Tibanne under the brand Kalyhost, Karpelès received a request from a French customer based in Peru who was frustrated with international payment hurdles. “He’s the one who discovered Bitcoin, and asked me if he could use Bitcoin to pay for my services ... I was probably one of the first companies to implement Bitcoin payments back in 2010”. Roger Ver, an early evangelist, became a frequent visitor to Karpelès’ office. Unknowingly, his servers also hosted a domain linked to Silk Road-silkroadmarket.org-purchased anonymously with bitcoin. That connection would later fuel investigations: U.S. authorities briefly suspected Karpelès of being Dread Pirate Roberts himself. “That was actually one of the main arguments why I was investigated by U.S. law enforcement as maybe the guy behind the Silk Road... They thought that I was Dread Pirate Roberts”. The association complicated public perception and even surfaced in Ross Ulbricht’s trial, where, according to Karpelès, Ulbricht’s defense efforts briefly tried to cast doubt by linking Karpelès to the marketplace. In 2011, Karpelès acquired Mt. Gox from Jed McCaleb, who went on to found Ripple and Stellar. The handover was marred from the start. “Between the time I signed the contract and the time I got access to the server, 80,000 bitcoins were stolen... Jed was adamant that we couldn’t tell users about it,” Karpelès alleged to Bitcoin Magazine. McCaleb faced no criminal liability for the Mt. Gox case, though he has been sued civilly and has been part of the public discourse around the case. Nevertheless, as far as Karpelès is concerned, he inherited a platform plagued by poor code and technical issues. Mt. Gox exploded in popularity, becoming the primary on-ramp for millions entering Bitcoin. Karpelès maintained strict policies, banning users linked to illicit activities like drug purchases on Silk Road. “If you’re going to buy drugs with Bitcoin, in a country...
