Bitcoin - Reward Comes With Risk - Part Four

by Dorsey & Whitney LLP

The nature and prospects of “virtual currencies”, and bitcoin in particular, have been keenly debated. Virtual currency systems arguably have positive aspects if they contribute to financial innovation and provide payment alternatives to consumers. However, they also pose risks for users, especially due to the lack of regulation aimed at consumer protection. These risks were underlined in the recent warning on virtual currencies issued by the European Banking Authority (EBA). This eUpdate is the fourth part in a series of eUpdates on bitcoin-related topics and issues. The first part of the series described what bitcoin is. The second part explained the legal status of bitcoin and how it is approached in different countries. The third part analyzed the effects of the Chinese demand on bitcoin, as well as how bitcoin is defined in China.

Controversies over virtual currencies

Virtual currencies are embroiled in controversies. They are often associated with being a monetary alternative for illegal activities, as well as with users claiming loss through cyberattacks or fraud.

Recent cases include the following:

  • In October 2013, Silk Road, an online marketplace, ceased to operate due to allegations that it allowed more than a billion U.S. dollars of illegal drugs and illicit services to be bought using bitcoin.
  • Another website, Sheep Marketplace, used bitcoin and the browser Tor1 to enable online sales of illicit goods, similar to Silk Road.2 It was launched in March 2013 and ceased to operate in early December 2013, after approximately US$5 million worth of bitcoins were stolen from the website.3 It was later reported that another US$44 million worth of bitcoins may also have been stolen from the users of Sheep Marketplace. A tech reporter for Forbes said that the closure of Sheep Marketplace was only the latest event in a “widening crisis” that was hitting drug sellers operating via the “dark net”. He cited the examples of two other sites, Atlantis and Project Black Flag, which shut down following the FBI seizure of Silk Road.4
  • Bitcoin was featured in the news on a cyberattack of the database belonging to the Japan-based bitcoin exchange Mt. Gox in June 2011. This news managed to knock the value of the currency down from US$17.50 to US$0.01 within minutes. Around 400,000 bitcoins (worth almost US$9 million) were affected.5 In addition, the perpetrator hacked into the Mt. Gox database, gaining access to usernames, e-mail addresses and passwords of thousands of users. Mt. Gox responded by closing down the system for a few days, promising that the transactions carried out by the hacker would be reversed. Bitcoin defenders claim that the bitcoin system did not fail, and that the problem was related to a particular bitcoin trading platform – Mt. Gox – which did not have sufficient security measures in place.
  • Another similar case occurred in May 2012, when Bitcoinica, a bitcoin exchange platform, lost 18,547 bitcoins from its deposits following a cyberattack, in which sensitive customer data might also have been misappropriated.6
  • In early November 2013,, a website owned by bitcoin payment processor TradeFortress, was attacked. Hackers allegedly stole more than US$1 million worth of bitcoins belonging to TradeFortress users, fuelling concerns about the security of the bitcoin system.7
  • In late October 2013, the Hong Kong-registered Global Bond Limited, a bitcoin trading platform, simply disappeared overnight, allegedly taking around US$4.1 million of investor money along with it.

These are but a handful of many other recently reported cases involving virtual currencies.8

Bitcoin-specific characteristics make it particularly attractive for illegal activities:

  • Bitcoin is a virtual currency that is not regulated, backed, guaranteed or protected by any central bank or government.
  • Bitcoin is based on a decentralized, peer-to-peer network, which means that there is no central authority in charge of it.
  • Bitcoin transactions are virtually anonymous as parties’ identities are not disclosed.
  • Bitcoin has no intrinsic value; its value depends largely on people’s confidence in the virtual currency.

The bitcoin system demonstrates a clear case of information asymmetry. On the one hand, it is complex and therefore not easily understood by users. On the other hand, the bitcoin software application is easily downloadable and used by users as such, even if they do not fully understand how the system works or appreciate the risks.

These features, in the context of legal uncertainty and the lack of close oversight, lead to a high-risk situation. Bitcoin is a high-risk system for its users from a financial perspective, as it could collapse if people attempt to exit the system en masse but are unable to do so due to its illiquidity.9 The fact that the founder of bitcoin uses a pseudonym – Satoshi Nakamoto – and is surrounded by mystery does not help promote transparency and credibility in the system.

Risks for virtual currency users

Virtual currencies, including bitcoin, raised untested legal concerns, in particular related to consumer protection. There is no specific regulatory protection to cover users’ losses if, for example, a virtual currency trading platform fails or goes out of business, or if its users’ digital wallets get hacked and virtual currency gets stolen. Therefore, buying, spending, holding or trading virtual currencies such as bitcoin involves a number of risks for their users.

As regulatory attention to bitcoin increased globally and its exchange rates became extremely volatile, a number of government authorities around the world began to take measures to address the user-related risks involved. On December 12, 2013, the EBA issued a warning to consumers on virtual currencies.10 The EBA’s warning followed similar announcements from the central banks of China, France and New Zealand. India was also reported to soon issue a public advisory to warn against potential risks associated with “this new digital currency concept”.11

The EBA identified several characteristics and risks that users should be aware of when dealing with bitcoin or similar virtual currency12. Such risks include the following:

  • Money can be stolen from digital wallets: Virtual currencies are stored in users’ “digital wallets”, on computers, laptops or smart phones. Digital wallets are not impervious to hackers; therefore, virtual currencies can be stolen from such wallets. In addition, if a user loses the key or password to the digital wallet, the virtual currency belonging to such user could be lost forever. There are no central agencies that record passwords or issue replacement ones.
  • There is no protection in using virtual currencies as a means of payment: When using virtual currencies as a means to pay for goods and services, users are not protected by any refund rights under any law. Unauthorized or incorrect debits from digital wallets are therefore not usually reversed. Acceptance of virtual currencies by retailers is not permanently guaranteed and is based on their discretion or contractual agreements, which may cease at any point without notice.
  • Money can be lost on exchange platforms: Virtual currency exchange platforms tend to be unregulated. They may go out of business or fail, for instance, due to hacking by third parties. Such exchange platforms are not banks that hold their virtual currency as a deposit. If an exchange platform loses any money or fails, there is no specific legal protection (such as, e.g., through a deposit guarantee scheme), which covers a user for losses arising from any funds held on the exchange platform, even if the exchange is registered with a national authority.
  • Value of virtual currencies can change quickly, or even evaporate completely: The value of virtual currencies has been extremely volatile and can easily go down as well as up. There is no assurance that the value of virtual currencies will remain largely stable.
  • Transactions in virtual currencies may be misused for criminal activities, including money laundering: Transactions in virtual currencies are public, but the parties of the transactions are not. Transactions are largely untraceable and provide virtual currency users with a high degree of anonymity. It is therefore possible that the virtual currency network will be used for transactions associated with criminal activities, including money laundering. This misuse could affect virtual currency users, as law enforcement agencies may decide to close exchange platforms and prevent users from accessing or using any funds that the platforms may be holding for them. 
  • Virtual currency users may be subject to tax liabilities: Holding virtual currencies may have tax implications, such as value added tax or capital gains tax. Their users should consider whether tax liabilities apply.

The EBA warned that virtual currency users should be fully aware of and understand specific characteristics of such currencies. Users should not spend “real” money to buy virtual currencies that they cannot afford to lose. They should exercise the same caution with digital wallets as they would do with their physical wallets, e.g., they should not keep large amounts of money in digital wallets for an extended period of time, and should ensure that virtual currencies are kept safe and secure. They should also familiarize themselves with the ownership, business model, transparency, and public perception of the virtual currency exchange platforms that they are considering using. The EBA has not suggested any other measures for protection of virtual currency users or their virtual property or any further steps in this direction. While bitcoin and similar virtual currency prices slightly dropped after the EBA’s warning, they quickly bounced back.

Issues associated with virtual currencies also apply to cash or other forms of “real” money. Nevertheless, virtual currencies have unique characteristics which may attract further regulatory attention.
