As per Wikipedia A cryptocurrency (or crypto currency) is a digital
asset designed
to work as a medium of exchange that uses cryptography to secure its transactions, to
control the creation of additional units, and to verify the transfer of assets.[1][2][3] Cryptocurrencies
are classified as a subset of digital
currencies and
are also classified as a subset of alternative currencies and virtual
currencies.
Cryptocurrencies use decentralized control[4] as opposed to centralized electronic
money and central
banking systems.[5] The
decentralized control of each cryptocurrency works through a blockchain, which is a public transaction database,
functioning as a distributed ledger.[6]Also,
there are several types of cryptocurrencies that generates in a different way
and distributing them to the peers over network.[7]
It can be understood in following in simple way by
following statements
1.
It is a digital currency in which encryption
techniques are used to regulate the generation of units of currency and verify
the transfer of funds, operating independently of a central bank.
2.
As of
January 2018, there were over 1384 and growing digital currencies in
existence. The most popular crypto currency is Bitcoin.
3.
"decentralized cryptocurrencies such as
bitcoin now provide an outlet for personal wealth that is beyond restriction
and confiscation
4.
Bitcoin uses
peer-to-peer technology to operate with no central authority or banks; managing
transactions and the issuing of bitcoins is carried out collectively by the
network.
5.
Bitcoin is open-source; its design is public, nobody
owns or controls Bitcoin and everyone can take part.
6.
The first Bitcoin
specification and proof of concept was published in 2009 by an unknown
individual under the pseudonym Satoshi Nakamoto who revealed little about
himself and left the project in late 2010.
The Bitcoin community has since grown
exponentially. Satoshi's anonymity often raises
unjustified concerns because of a misunderstanding of the open-source nature of
Bitcoin. From a user perspective, Bitcoin is nothing more than a mobile app or
computer program that provides a personal Bitcoin wallet and enables a user to
send and receive bitcoins.Behind the scenes, the Bitcoin network is sharing a
massive public ledger called the "block chain".This ledger contains
every transaction ever processed which enables a user's computer to verify the
validity of each traBitcoins are stored in a “digital wallet,” which exists
either in the cloud or on a user’s computer. The wallet is a kind of virtual
bank account that allows users to send or receive bitcoins, pay for goods or
save their money. Unlike bank accounts, bitcoin wallets are not
insured by the FDIC. Many people new to Bitcoin are curious about how to get
some.Bitcoin faucets, places where bitcoins are given away for free, have been
a part of spreading Bitcoin since the earliest days. But one problem is running
out of bitcoins to give! That is why we have figured out a sustainable way to
give away free bitcoins with

Mobile Payments
Like with many online payment systems, Bitcoin users can pay for their coins anywhere they have
Internet access. This means that purchasers never have to travel to a bank or a
store to buy a product. However, unlike online payments made with U.S. bank
accounts or credit cards, personal information is not necessary to complete any
transaction.No one knows
what will become of bitcoin. It is mostly unregulated, but that could change. Governments
are concerned about taxation and their lack of control over the currency.

LOOSE ALL THEIR MONEY said the EU. These currencies are highly risky and
subject to extreme volatile in nature. This warning was published by European
commission vice president Valdis Dombrovskis recently. They are arranging
meeting of key persons soon in this regard.
