More than 100 investors attended the meeting at a courthouse in the Japanese capital, demanding to know how some $500 million worth of Bitcoins disappeared from Mt. Gox’s digital vaults earlier this year.

People who attended the meeting said former Mt Gox chief Mark Karpeles and a court-appointed lawyer managing the firm’s bankruptcy proceedings gave no clear answer about what happened to their money.

The meeting was designed to discuss the bankruptcy process itself and they separated that from what happened to Bitcoin,” said 50-year-old Toshiya Takahashi. “What people wanted to know was what happened and why.”

Karpeles also refuses to travel to the United States, where he was being asked to appear in Texas for questioning in connection with Mt Gox’s collapse. There have also been calls in Japan to launch a criminal investigation.

The next creditors’ meeting is slated for Nov 26

So far the group has offered a token sum of 1 Bitcoin for Mt. Gox.

Who Is Mark Karpeles?

28-year-old Mark Karpeles was born in France, then spent time in Israel and finally settled down in Japan. There he got married and became a father.

Mark Karpalese worked as a software developer and network admin at Linux Cyberjoueurs and has also contributed to PHP  official repository of extensions from 2003 – 2005

In 2009 he founded Tibanne Co. Ltd where he is CEO. Mark is  also a founding member of the Bitcoin Foundation created in 2012 with a mission to standardize and promote bitcoin.

While at Mt. Gox insiders say he was a man who “was more a computer coder than a Chief-Executive and yet was sometimes distracted even from his technical duties when they were most needed”

In 2011, he acquired the Mt. Gox exchange in from an American entrepreneur named Jed McCaleb.



According to insiders, he thought nothing of dropping the business of the day to order flat screen TVs or $400 lunches for the staff of Gox’s expanded Tokyo headquarters, which now occupies three floors of a modern office building in the city’s Shibuya neighborhood.

Amid all the rapid expansion of Mt. Gox – it seems like Karpeles was unimpressed as he took up a brand new project; The Bitcoin Cafe. Inspired by a French bistro, it would be a stylish hang-out located in the same building as the Mt. Gox offices, a very-new-looking building of metal and glass within walking distance of Tokyo’s largest train station. You could drop by for a beer or some wine, and — using a cash register proudly hacked by Mark Karpeles — you could buy it all with bitcoin.

One insider says that Mt. Gox spent the equivalent of $1 million on the cafe venture, renovating Mt. Gox’s office building to Karepeles’ specifications. At a time when Gox’s business was falling apart, this insider says, the project was a major distraction. “[Karpeles] was super-proud of being able to use his hacked cash register with the code he wrote,” this insider says.

Says another insider: “Aside from the cafe, he liked to spend time fixing servers, setting up networks and installing gadgets… probably distracting himself from dealing with the real issues that the company was up against.”

A very telling example of how Mark Karpelese conducted his business occurred in June 2011 amid the first Mt. Gox Hack

Ver and Powell and Karpeles were set to work through the weekend, but when they arrived at the company’s tiny office that Saturday, there was a surprise. Mark Karpeles had decided to take the weekend off. The two volunteers were flabbergasted. “I thought that was completely insane and demoralizing for the rest of the team,” Powell remembers.

On Monday, Karpeles did return to work, but he spent part of the day stuffing envelopes. “I was like: ‘Dude why are you doing this? You can do this anytime. The site is offline. You need to get the site online.’”

The lack of sense of urgency and a big ego – it seems like Mark Karpeles is living in another universe and cares not for his clients nor customers.

Further re-enforced by his twitter feed after the Mt. Gox crash. After months of dark social media account @magicaltux was back tweeting about asian noodles sparking outrage within the bitcoin online community.
