What is a cryptocurrency?


 cryptocurrency
A cryptocurrency is a medium of exchange using cryptography to secure the transactions and to control the creation of new units. Cryptocurrencies are a subset of alternative currencies, or specifically of digital currencies.

Cryptocurrencies use decentralized control as opposed to centralized electronic money/centralized banking systems. The decentralized control is related to the use of bitcoin's block chain transaction database in the role of a distributed ledger.

There were more than 669 cryptocurrencies available for trade in online markets but only 10 of them had market capitalizations such as Bitcoin, Litecoin, DogeCoin, Peercoin, Ripple, NXT, MasterCoin, Namecoin, Quark, ProtoShares, ect.

Cryptocurrency is a virtual Currency
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 Financial Crimes Enforcement Network(FinCEN), a bureau of the US Treasury, defined virtual currency in its guidance published in 2013. In 2014, the European Banking Authority defined virtual currency 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".

In 2013, Financial Crimes Enforcement Network (FinCEN), a bureau of the US Treasury, in contrast to its regulations defining currency as "the coin and paper money of the United States or of any other country that (a) is designated as legal tender and that (b) circulates and (c) is customarily used and accepted as a medium of exchange in the country of issuance", also called "real currency" by FinCEN, defined virtual currency as "a medium of exchange that operates like a currency in some environments, but does not have all the attributes of real currency". In particular, virtual currency does not have legal tender status in any jurisdiction.
