What Is A Cryptocurrency? — The Beginner’s Guide:
A cryptocurrency is a medium of exchange like normal currencies such as USD, but designed for the purpose of exchanging digital information through a process made possible by certain principles of cryptography. Cryptography is used to secure the transactions and to control the creation of new coins. The first cryptocurrency to be created was Bitcoin back in 2009. Today there are hundreds of other cryptocurrencies, often referred to as Altcoins.
Put another way, cryptocurrency is electricity converted into lines of code with monetary value. In the simplest of forms, cryptocurrency is digital currency.
Unlike centralized banking, like the Federal Reserve System, where governments control the value of a currency like USD through the process of printing fiat money, government has no control over cryptocurrencies as they are fully decentralized.
Most cryptocurrencies are designed to gradually decrease production of that currency, placing a cap on the total amount of that currency that will ever be in circulation. Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement.[1] This difficulty is derived from leveraging cryptographic technologies.
Cryptocurrencies make it easier to transfer funds between two parties in a transaction; these transfers are facilitated through the use
A cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. 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.
A cryptocurrency (or crypto currency) is a digital asset 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 use decentralized control as opposed to centralized digital currency 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 6,000 altcoins (alternative variants of bitcoin, or other cryptocurrencies) have been created.

A cryptocurrency is a digital or virtual currency designed to work as a medium of exchange. It uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency. Essentially, cryptocurrencies are limited entries in a database that no one can change unless specific conditions are fulfilled.
The first cryptocurrency to capture the public imagination was Bitcoin, which was launched in 2009 by an individual or group known under the pseudonym Satoshi Nakamoto. As of September 2015, there were over 14.6 million bitcoins in circulation with a total market value of $3.4 billion. Bitcoin’s success has spawned a number of competing cryptocurrencies, such as Litecoin, Namecoin and PPCoin.
A cryptocurrency is a form of digital currency that is designed to be secure and, in many cases, anonymous. It is a currency associated with the internet that uses cryptography, the process of converting legible information into an almost uncrackable code, to track purchases and transfers. Cryptography was born out of the need for secure communication in the Second World War.[4] It has evolved in the digital era with elements of mathematical theory and computer science to become a way to secure communications, information and money online.
The first cryptocurrency was bitcoin, which was created in 2009 and is still the best known. There has been a proliferation of cryptocurrencies in the past decade[5] and there are now more than 900 available on the internet.[6]
In 2017 bitcoin’s value soared from $1000 to just under $20,000 before dropping down to around $13,000 at the end of the year. Since then it has regained lost ground, so whether or not it will eventually turn out to be a good investment or just a passing fad remains to be seen. Bitcoin can only be used as a medium of exchange and in practice has been far more important for the dark economy than it has for most legitimate uses.
The semi-anonymous nature of cryptocurrency
Before we get started, let’s go over some basic terminology. A cryptocurrency is a digital or virtual currency that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend. Many cryptocurrencies are decentralized networks 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.
The word cryptocurrency was first used in 2009 when Bitcoin was launched. However, at the time people were unsure what to call it. Although there have been attempts to create digital currencies since the 1990s, they never caught on. The emergence of Bitcoin changed this.
Today there are around 1,500 different cryptocurrencies available to buy and sell online (such as Ethereum and Ripple). We expect this number to increase significantly in the coming years as the crypto market continues to mature and grow.
Simply put, a cryptocurrency is a new form of digital money. You can transfer your traditional, non-cryptocurrency money like the U.S. dollar digitally, but that’s not quite the same as how cryptocurrencies work.
Here’s the key difference: cryptocurrencies use decentralization and cryptography (hence the crypto in cryptocurrency) to make transactions secure and reliable – and to control the creation of new units of a particular cryptocurrency.
The best way to understand this is through an example: Bitcoin is one of the most popular types of cryptocurrencies today; it was created in 2009 by Satoshi Nakamoto (the pseudonym used by its mysterious creator). Bitcoin is a decentralized currency, which means it doesn’t have a single administrator or central bank that controls it. Instead, it uses blockchain technology to record its transactions on many computers around the world in such a way that no single entity – not even its creator – can alter the records. The data stored on the blockchain is also open for anyone to see, so there are no hidden transactions.
In addition to being decentralized, Bitcoin is also pseudonymous, meaning users don’t need to provide their real names when creating a Bitcoin wallet or making transactions with it.
