What is a cryptocurrency?
A cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. Many cryptocurrencies are decentralized systems based on blockchain technology, a distributed ledger enforced by a disparate network of computers. A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation.
Cryptocurrencies are systems that allow for the secure payments online which are denominated in terms of virtual “tokens,” which are represented by ledger entries internal to the system. “Crypto” refers to the various encryption algorithms and cryptographic techniques that safeguard these entries, such as elliptical curve encryption, public-private key pairs, and hashing functions.
Alongside this important “crypto” feature of these currencies is a common commitment to decentralization; cryptocurrencies are typically developed as code by teams who build in mechanisms for issuance (often, although not always, through a process called “mining”) and other controls. Cryptocurrencies are almost always designed to be free from government manipulation and control, although as they have grown more popular this foundational aspect of the industry has come under fire. The currencies modeled after bitcoin are collectively called altcoins and have often tried to present themselves

A defining feature of a cryptocurrency, and arguably its most endearing allure, is its organic nature; it is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
Bitcoin, first released as open-source software in 2009, is generally considered the first decentralized cryptocurrency.[6] Since the release of bitcoin, over 4,000 altcoins (alternative variants of bitcoin, or other cryptocurrencies) have been created.
Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the Federal Reserve System, corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers. In case of decentralized cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for other firms, banks or corporate entities which hold asset value measured in it. The underlying technical system upon which decentralized cryptocurrencies are based was created by the group or individual known as Satoshi Nakamoto.[7]

A cryptocurrency is a digital currency that uses cryptography for security and anti-counterfeiting measures. Public and private keys are often used to transfer cryptocurrency between individuals.
Cryptocurrencies are a subset of alternative currencies, or specifically of digital currencies. Bitcoin became the first decentralized cryptocurrency in 2009. Since then, numerous cryptocurrencies have been created. These are frequently called altcoins, as a blend of Bitcoin alternative. Bitcoin and its derivatives use decentralized control as opposed to centralized electronic money/centralized banking systems. The decentralized control is related to the use of bitcoins block chain transaction database in the role of a distributed ledger.

Decentralized cryptocurrencies such as bitcoin now provide an outlet for personal wealth that is beyond restriction and confiscation.*
You might have heard the news that cryptocurrency values are skyrocketing, but what exactly is a cryptocurrency?
A cryptocurrency is a kind of digital money that is designed to be secure and, in many cases, anonymous. Cryptocurrency uses cryptography as a security measure to prevent counterfeiting and other kinds of fraud.
One of the main characteristics of cryptocurrency is that it isn’t controlled by any central authority: the decentralized nature of blockchain makes cryptocurrency theoretically immune to the old ways of government control and interference. Cryptocurrencies can be sent directly between two parties via the use of private and public keys. These transfers can be done with minimal processing fees, allowing users to avoid the steep fees charged by traditional financial institutions.
The security aspect is also pretty robust. Because cryptocurrencies are virtually impossible to counterfeit, there’s no risk of chargebacks or fake returns. This makes merchants who accept them more comfortable because there’s no risk for them. Finally, the anonymity part comes into play because you don’t have to provide any personal information in order to send or receive cryptocurrencies.
A cryptocurrency is a medium of exchange, such as the US dollar, but is digital and uses encryption techniques to control the creation of monetary units and to verify the transfer of funds.
The key difference between a cryptocurrency and a traditional currency is that it’s decentralized. Instead of being controlled by governments or banks, cryptocurrencies are decentralized across a network of computers that anyone can access. Because they’re not tied to any one particular country or central bank, they aren’t vulnerable to the same policies or economic conditions that affect traditional currencies.
In other words, cryptocurrencies are “an Internet-wide distributed ledger,” says Peter Van Valkenburgh, director of research at Coin Center, a nonprofit focused on public policy issues around cryptocurrency. “Anyone can download it for free, and you can use it to track who owns what bitcoin.”
Instead of relying on a third party like a bank to process transactions, cryptocurrencies use encryption techniques that enable two parties to transfer value directly to each other without involving any middlemen.
Cryptocurrencies are digital assets designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets. Cryptocurrencies are a kind of alternative currency and digital currency (of which virtual currency is a subset). Cryptocurrencies use decentralized control as opposed to centralized electronic money and central banking systems. The decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.
Bitcoin, first released as open-source software in 2009, is generally considered the first decentralized cryptocurrency. Since the release of bitcoin, over 4,000 altcoins (alternative variants of bitcoin, or other cryptocurrencies) have been created.
In 1983 the American cryptographer David Chaum conceived an anonymous cryptographic electronic money called ecash.[7][8] Later, in 1995, he implemented it through Digicash,[9] an early form of cryptographic electronic payments which required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by the issuing bank, the government, or any third party.
