A virtual currency or virtual money has been defined in 2012 by the European Central Bank as "a type of unregulated, digital money, which is issued and usually controlled by its developers, and used and accepted among the members of a specific virtual community". The US Department of Treasury in 2013 defined it more tersely as "a medium of exchange that operates like a currency in some environments, but does not have all the attributes of real currency". The key attribute a virtual currency does not have at this time, is the status as legal tender.

In 2012, the European Central Bank defined it as "a type of unregulated, digital money, which is issued and usually controlled by its developers, and used and accepted among the members of a specific virtual community".:13
In 2014, the European Banking Authority defined it as "a digital representation of value that is neither issued by a central bank or a public authority, nor necessarily attached to a fiat currency, but is accepted by natural or legal persons as a means of payment and can be transferred, stored or traded electronically".
History of the term
In his written testimony to the 2013 congressional hearing on virtual currencies Ben Bernanke stated "virtual currencies have been viewed as a form of “electronic money” or area of payment system technology that has been evolving over the past 20 years", reminding of a congressional hearing on the Future of Money before the Committee on Banking and Financial Services on 11 October 1995. The Internet currency Flooz was created in 1999. The term virtual currency appears to have been coined around 2009, paralleling the development of digital currencies and social gaming.
Although media have used the term 'digital currency', US government institutions have preferred and uniformly adopted the term 'virtual currency', first the US Treasury's Financial Crimes Enforcement Network (FinCEN) above, then the FBI in 2012, the General Accounting Office in its 2013 report and other government agencies testifying at the November 2013 Senate Hearing about Bitcoin like the Department of Homeland Security, the U.S. Securities and Exchange Commission, the Office of the Attorney General.
Limits on being currency
The IRS decided in March 2014, that Bitcoin and other virtual currencies are treated as property for IRS purposes, not currency. This means Bitcoins are not fungible - that is one bitcoin is not identical to another bitcoin, unlike one ounce of gold being identical to any other ounce of gold. Some have suggested that this makes it unworkable as a currency. Others have stated that "Bitcoin is entirely fungible when it’s being spent. It isn’t fungible as to where and how and at what price I earned it."
Centralized and decentralized classifications
FinCEN further distinguishes virtual currencies between 'centralized' and 'decentralized'. In business studies, centralization refers to where decisions are made in the hierarchy of a business. Depending on the degree of currency convertibility
Closed virtual currencies
Virtual currencies have been called "closed", when they have no connection to the real economy, like currencies "in-online -games-only" such as World of Warcraft (WoW). While there may be a black market for exchanging WoW Gold against real world assets, it is expressedly forbidden by the owner of WoW.
Virtual currency with currency flow into one direction
This type of currency has been known for a long time in the form of customer incentive programs or loyalty programs. The first known coupon in history is probably from the US, attributed to Asa Candler, inventor of Coca-Cola and the free drink coupons in 1887, followed by C. W. Post's one-cent-off coupon in breakfast cereal boxes in 1895, both to drive sales. The business issuing the coupon functions as a central authority Coupons remained unchanged for 100 years until new technology enabling credit cards became more common in the 1980s, and credit card rewards were invented. The latest incarnation is online the increase of internet commerce, online services, development of online communities and games. Here virtual or game currency can be bought, but not exchanged back into real money. The virtual currency is akin to a coupon . Examples are frequent flyer programs by various airlines, Nintendo and -for a while- Facebook, whose points since 2012 can be changed back to money.
Virtual currencies open in both directions
A virtual currency that can be bought with and sold back for legal tender is called a convertible currency. It can be centralized as in Linden Dollars in the online virtual economy of Second Life or decentralized, as for example Bitcoin.
Centralized versus decentralized virtual currencies
FinCEN defined centralized convertible virtual currencies in 2013 as convertible virtual currencies that have a "centralized repository", similar to a central bank. FinCEN distinguished between two scenarios: One where an exchanger of a virtual currency sells and accepts real money for it, which defines the exchanger as a money transmitter, subject to the US Bank Secrecy Act, and two, where the money exchanger sells convertible virtual currency indirectly to a third party account and in a way that is "not completely transparent" 
A decentralized currency was defined by the US Department of Treasury as a "currency (1) that has no central repository and no single administrator, and (2) that persons may obtain by their own computing or manufacturing effort". Rather than relying on confidence in a central authority, it depends instead on a distributed system of trust.
Bitcoin, an example of a decentralized, convertible virtual currency
Bitcoin is the first truly decentralized global currency system, and at the same time the largest virtual currency as of 2014. Trust in the currency is based on the "transaction ledger which is cryptographically verified, and jointly maintained by the currency’s users". The Bitcoin Foundation claims, Bitcoin was "designed to be fully decentralized with miners operating in all countries, and no individual having control over the network", and that Bitcoin is "as virtual as the credit cards and online banking networks people use everyday".
However, the increasing centralization of Bitcoin has become more visible over the years, leading cryptologic researchers to question if Bitcoin is indeed a decentralized currency. To improve Bitcoin's decentralization, they suggest to encourage fully decentralized mining pools, allow only 1 vote per Bitcoin client, and to increase transparency in decision making.
Distinction from digital currency and cryptocurrency
A cryptocurrency is a particular type of a digital currency, and both are virtual currencies. The reverse does not hold, since virtual currencies don't have to use cryptography. According to the European Central Bank (ECB) definition, virtual currencies are generally digital, although its enduring precursor, the coupon for example, is physical. In the present day usage of the term virtual currency, in environments with digital communication and with disappearing importance of physical coupons, digital currency equals virtual currency, as defined by ECB and the Treasury.
Virtual currencies pose challenges for central banks, financial regulators, departments or ministries of finance, as well as fiscal authorities and statistical authorities. Gareth Murphy, Central Bank of Ireland, described the regulatory challenges posed by virtual currencies through the prism of a structured framework of regulatory engagement. The challenges relate to:
- Economic Statistics
- Monetary and Exchange Rate Policy
- Tax Leakage
- Payments Systems and Settlement Infrastructure
- Consumer Protection
- Anti-Money Laundering
- Impact on Regulated Financial Service Providers
