In August, law fat was arrested by Japanese police, was accused of fraud, embezzlement and manipulation of “Mentougou” computer system. These charges and 650 thousand bitcoin theft incident has no direct relationship.

A sad and dirty story

It is not just the end.

In one of the victims of Japanese life and work of the Swedish Kim Nilsson is “Mentougou”. When they find themselves in the “Mentougou” bitcoin out when he is collapsing, “there’s a law? There are laws?”

Kim Nilsson

However, Kolin and Burges choose to protest, he chose another way. He and other victims of two Daniel Kelman and Jason Maurice, set up a “WizSec” company, dedicated to investigating the theft.

Although the Kolin Burges has two partners, but basically is the only person in the technical aspects of living. During the day, he had to go to work at night, only in their own homes, with the broken computer to buy online survey.

Kolin Burges developed a program to search, input and output address of each transaction. Kolin Burges also received the “database information, a part of Mentougou” leaked to the Internet, “including trading, withdrawals, deposits and balances the user’s privacy record”.

Finally, he won nearly two million associated with the Mt.Gox trading platform. However, he did not know the address is who.

In order to make clear the address who is, they need to know to help, so they use the dared. Daniel Kelman started online accused the money corruption law fat. Because fat also wants to find out the truth, also own a clean. Then, by fat and Daniel agreed to meet Kelman, Kim Nilsson, and help them understand the integrity of the “Mentougou”.

Even so, Kim Nilsson still can not find out exactly who is doing.

In a later analysis, Kim Nilsson found in a transaction, the transaction with a message, with only three letters “WME”. This became the only clue.

In a series of investigations, Kim Nilsson, WME and an operating in Moscow digital currency trading company. “2011 years, WME has appeared on the board of directors of BitcoinTalk, was also used on the bulletin board BitcoinTalk said” Hello, I have 10 years of time in the money exchange. Now, I began to use bitcoin, can I change anything. If there are a large amount of money exchange, I will give priority to. “”.

So, who is this WME? WME usually very careful, can not find what information, but still left some traces.

In 2012, a “WME” account made a post on the Internet, “said another trading platform is the use of my money fraud and escape”. Never thought that this “WME” also posted some information, including his digital currency address: a “VINNIK ALEXANDER” which owns the account.

The name “VINNIK ALEXANDER” surfaced.

Kim Nilsson will be the name passed to the IRS IRS agent Gary Alford. This is the 2016 year of the summer, from the “Mentougou” has filed for bankruptcy in the past two years.

In July 27, 2017, after several years of investigation, WizSec released the investigation report, as follows:

In September 2011, the “stolen Mentougou” hot wallet private key, hackers constantly use this key to steal bitcoin, and put the bitcoin into “VINNIK ALEXANDER” control wallet. In 2013, hackers have been stealing 630 thousand bitcoin. When the coins into the “VINNIK ALEXANDER” control the wallet, most are transferred to the trading platform. “VINNIK ALEXANDER” bitcoin includes not only the “Mentougou” stolen bitcoin, including Bitcoinica, Bitfloor stolen bitcoin.

7 months to 2017 years, the U.S. authorities arrested Russian Alexander Vinnik in greece.

Alexander Vinnik was arrested

Although Alexander Vinnik has been arrested, but it is not completely white in the world, the case is still pending, “the bankruptcy procedure is still in Mentougou. The message says, “Mentougou” will be held next year, 2019 is the compensation for the loss of users.

Because of the position and influence of Mentougou “at that time, the number of stolen bitcoin is large, the price of bitcoin caused a great impact, but also caused a great impact on people’s confidence. At that time, many people in the community of bitcoin downhearted.

“Mentougou” after the incident, the trading platform is black events still occur:

In March 2014, the United States digital currency exchange Poloniex stolen; January 2015, the world’s third largest bitcoin exchange Bitstamp is black; February 2015, bit children trading platform stolen; 2017, Korea Exchange Bithumb suffered two attacks.

Security is still a major pain points of the digital currency industry.

Later, Kolin Burges had a “Mentougou” protest site, specially published “the latest progress of Mentougou” protest as well as the contents of the case. An article in this website is the latest published in October 18, 2018, “remember you submit civil regeneration before October 22nd (Civil Rehabilitation) statement”.

Kolin Burges is still waiting for the law to help him recover.
