This shows a definite need for hot wallet insurance. Reduction in the level of funds stored in hot wallets would reduce the risk.

This exchange or platform is based in New Zealand, or the incident targeted people primarily in New Zealand.[1][2][3][4][5][6][7][8][9]

About Bitcoinica

The Bitcoinica exchange platform was based in New Zealand, and founded by Zhou Tong[1].

Despite his position as the creator of a financial speculation service and his strong belief in libertarian capitalist ideals, Bitcoinica to him has never been about the profit. “Bitcoinica is not a money making machine,” he writes. “It’s just a product that sets a high standard for the Bitcoin community.”[1]

The Reality

This sections is included if a case involved deception or information that was unknown at the time. Examples include:

  • When the service was actually started (if different than the "official story").
  • Who actually ran a service and their own personal history.
  • How the service was structured behind the scenes. (For example, there was no "trading bot".)
  • Details of what audits reported and how vulnerabilities were missed during auditing.

What Happened

The specific events of the loss and how it came about. What actually happened to cause the loss and some of the events leading up to it.

Technical Details

The vulnerability reportedly happened through a compromised email address, which had a higher level of permissions than necessary[10]. The chief transaction involved in the theft is 7a22917744aa9ed740faf3068a2f895424ed816ed1a04012b47df7a493f056e8[13].

BitcoinTalk Summary

[10]

Zhou Tong, former founder of Bitcoinica, discovered an entry into Bitcoinica's Rackspace server through an excessively privileged compromised email address. This caused the theft of the entire “hot wallet”, funds stored on-site, as well as the loss of the main database. No backups were kept. Bitcoinica shut down because of this incident. The claims process is still ongoing; however, Bitcoinica is now entering receivership.

Total Amount Lost

There are three different estimates of the amount lost in this case.

  • The first value of 18547.66867623 comes from the blockchain transaction[13]. This is included on some sites such as BitcoinTalk[10].
  • BitMarket.eu had a liquidation, and in the legal paperwork, they reported "about" 19980 bitcoins[10].
  • BitcoinTalk user dree12 reported a total amount affected reported to be at least 38527 bitcoin[10]. This is very similar to an estimate on Bitcoin.com, which reported that the exchange lost over 38,000 BTC during the spring incident, which refers to an event that breached Bitcoinica's Rackspace servers on May 12th, 2012[11].


The total amount lost has been estimated at $91,000 USD.

Immediate Reactions

“On May 6, 2012, bitcoin exchange Bitcoinica announced that their hot wallet had been hacked. The exchange told users that they had “discovered a suspicious bitcoin transaction that doesn’t seem to be initiated by any one of the company owners.” The hot wallet hack was initially suspected to be linked to Bitcoinica owner A. Vinnik, leading some to suspect it was an exit scam.”


"Today, we have discovered a suspicious Bitcoin transaction that doesn't seem to be initiated by any one of the company owners..." speculation has been that A. Vinnik was involved (same as Mt Gox, BTC-e)

Ultimate Outcome

What was the end result? Was any investigation done? Were any individuals prosecuted? Was there a lawsuit? Was any tracing done?

Zhou Tong Leaving Bitcoin

Founder Zhou Tong decided to leave bitcoin entirely[1].

“I always believe in Bitcoin, or simply anything that brings people financial liberty. I have heavily invested in Bitcoin (I purchased one 1,000 BTC gold coin from Casascius and will keep it for as long as I can).”

Vitalik Buterin had strong praise for Zhou Tong and criticized his critics[1].

Zhou Tong has often been reviled as a scammer, and this crisis has, predictably, only amplified such cries. But his actions over the past eight months do not paint the picture of a man who consciously set out to defraud the public with a Ponzi scheme or an arcane system of liquidation rules; rather, they paint the picture of a teenager, still uncorrupted by the rigidities of the status quo, ready to discover the world and find a place where he can make a difference. Of course, Bitcoinica’s history is marked by security blunders and telling signs of Zhou’s inexperience. However, failure is an inevitable part of learning and innovation, and if the Bitcoin community begins to treat failure as an unforgivable sin and every blunder as proof of moral turpitude, then it will cease to be a community that values learning and innovation at all. Instead, it will become yet another manifestation of the inflexible and bureaucratic status quo.

Lawsuit Against Platform

Finextra reports that four former users of Bitcoinica have filed a lawsuit alleging that they are owed nearly half a million dollars in missing funds, as well as damages[12]. Bitcoinica, once a successful exchange created by teenager Zhou Tong, suffered two major hacking incidents earlier this year, resulting in the theft of thousands of Bitcoins. Despite assurances from Bitcoinica that the stolen funds were from the exchange itself and not customers, the site has remained offline, leaving users uncertain about the fate of their investments. Additionally, Bitcoinica had initially promised to honor all withdrawal requests but later informed users that only half of their funds would be returned, prompting speculation about the exchange's integrity. Amidst rumors implicating Tong in the hacks, the plaintiffs filed a complaint in San Francisco alleging that Bitcoinica, its successor Intersango, and associated individuals conspired to deprive them of their rights regarding the missing funds[12].

Inclusion In Incident Lists

This incident was included in many sources, including:

  • a list compiled by BitcoinTalk user dree12[10].
  • a Bitcoin Magazine infographic[14] (along with another Bitcoinica theft).
  • Bitcoin.news lists this as one of the most controversial in the industry[11].
  • Bitcoin Exchange Guide[15].
  • Slowmist[16].

Total Amount Recovered

There do not appear to have been any funds recovered in this case.

Ongoing Developments

There are a few potential ongoing developments.

Identity Of The Hacker

According to BitcoinTalk, the hacker is unknown[10].

Wendon Group Legal Action

Venture capital group Wendon Group threatened legal action against Bitcoinica Consultancy[10].

New Zealand Bankruptcy

A receivership in New Zealand was ongoing[10].
