The former CEO of collapsed bitcoin exchange Mt. Gox is to head to trial in Tokyo next week on charges stemming from the disappearance of hundreds of millions of US dollars worth of the virtual currency from its digital vaults.
Frenchman Mark Karpeles — once the high-flying head of the world’s busiest bitcoin trading platform, who reportedly lived in an US$11,000-a-month penthouse and spent money lavishly, including on prostitutes — is facing embezzlement and data manipulation charges.
“He is keeping calm as the trial gets underway,” his lawyer Kiichi Iino told reporters, adding that Karpeles plans to plead his innocence.

The 32-year-old was first arrested in August 2015 and released on bail nearly a year later over allegations he fraudulently manipulated data and pocketed millions worth of bitcoins.
Mt. Gox, which claimed it once hosted around 80 percent of global bitcoin trading, shuttered in 2014 after admitting that 850,000 coins — worth around US$480 million at the time — had disappeared from its vaults.
The Tokyo-based exchange filed for bankruptcy protection soon after the cyber-money went missing, leaving a trail of angry investors calling for answers and denting the virtual currency’s reputation.
Karpeles, who said he is working as an IT consultant, is active on social media and has commented on issues concerning bitcoin, but not on details of his criminal case.
“The charges [against Karpeles] only cover a subset of the issues which were happening at Mt. Gox, so I don’t expect that we will find out most of the information we want to know,” said Kolin Burges, a British investor who said he lost several hundred bitcoins in the Mt. Gox collapse.
“I’ve not had any back yet, but hopefully, eventually all the creditors will get a small percentage of their money back from the bankruptcy distribution,” he said.
Around the time of his 2015 arrest, Karpeles’ mother told the Yomiuri Shimbun that her son was a “genius” who learned computer languages at age three and started making simple programs by the time he was five.
In 2006, Karpeles wrote on his blog that computer crime was “totally contrary to my ethical principles.”
However, four years later, a Paris court sentenced him in absentia to a year in prison for hacking. He had come to Japan to work for a Web development company around 2009 and later got involved with the bitcoin exchange.
In the wake of the Mt. Gox scandal, Japan passed a bill stipulating that all virtual currency exchanges must be regulated by its Financial Services Agency.
Despite the demise of Mt. Gox and concerns about security, bitcoin and hundreds of rival digital currencies are becoming increasingly popular and accepted by merchants worldwide.
Bitcoin remains the most popular. Its market value has ballooned to more than US$42.9 billion, according to the coinmarketcap.com.
The unit has seen wild volatility during its short life, soaring from just a few US cents to around US$2,500 now, more than double its value just a few months ago.
Backers say virtual currencies offer an efficient and anonymous way to store and transfer funds online, but critics argue the lack of legal framework governing the currency, the opaque way it is traded and its volatility make it dangerous.
Six Taiwanese companies, including contract chipmaker Taiwan Semiconductor Manufacturing Co. (TSMC), made the 2025 Fortune Global 500 list of the world’s largest firms by revenue. In a report published by New York-based Fortune magazine on Tuesday, Hon Hai Precision Industry Co. (better known as Foxconn) ranked highest among Taiwanese firms, placing 28th with revenue of US$213.69 billion. Up 60 spots from last year, TSMC rose 60 places to reach No. 126 with US$90.16 billion in revenue, followed by Quanta Computer Inc. at 348th, Pegatron Corp. at 461st, CPC Corp., Taiwan at 494th and Wistron Corp. at 496th.

NEW PRODUCTS: MediaTek plans to roll out new products this quarter, including a flagship mobile phone chip and a GB10 chip that it is codeveloping with Nvidia Corp MediaTek Inc (聯發科) yesterday projected that revenue this quarter would dip by 7 to 13 percent to between NT$130.1 billion and NT$140 billion (US$4.38 billion and US$4.71 billion), compared with NT$150.37 billion last quarter, which it attributed to subdued front-loading demand and unfavorable foreign exchange rates. The Hsinchu-based chip designer said that the forecast factored in the negative effects of an estimated 6 percent appreciation of the New Taiwan dollar against the greenback. “As some demand has been pulled into the first half of the year and resulted in a different quarterly pattern, we expect the third quarter revenue to decline sequentially,”
WEAKER ACTIVITY: The sharpest deterioration was seen in the electronics and optical components sector, with the production index falling 13.2 points to 44.5 Taiwan’s manufacturing sector last month contracted for a second consecutive month, with the purchasing managers’ index (PMI) slipping to 48, reflecting ongoing caution over trade uncertainties, the Chung-Hua Institution for Economic Research (CIER, 中華經濟研究院) said yesterday. The decline reflects growing caution among companies amid uncertainty surrounding US tariffs, semiconductor duties and automotive import levies, and it is also likely linked to fading front-loading activity, CIER president Lien Hsien-ming (連賢明) said. “Some clients have started shifting orders to Southeast Asian countries where tariff regimes are already clear,” Lien told a news conference. Firms across the supply chain are also lowering stock levels to mitigate
DIVERSIFYING: Taiwanese investors are reassessing their preference for US dollar assets and moving toward Europe amid a global shift away from the greenback Taiwanese investors are reassessing their long-held preference for US-dollar assets, shifting their bets to Europe in the latest move by global investors away from the greenback. Taiwanese funds holding European assets have seen an influx of investments recently, pushing their combined value to NT$13.7 billion (US$461 million) as of the end of last month, the highest since 2019, according to data compiled by Bloomberg. Over the first half of this year, Taiwanese investors have also poured NT$14.1 billion into Europe-focused funds based overseas, bringing total assets up to NT$134.8 billion, according to data from the Securities Investment Trust and Consulting Association (SITCA),
