What is Cryptocurrency?

You must have heard these terms emanating from the media nowadays: “bitcoin, blockchain, cryptocurrency”. While the entire  Fintech and technology scene is being disrupted by an explosion of cryptocurrencies, it is very important to know what they are. At CoinRaver, we will walk you through all the nuances of cryptocurrencies, various crypto coins and more.

Cryptocurrency is a decentralised currency that is not owned by any one entity. It is a currency which is managed through the blockchain system. Various experts have touted cryptocurrencies as a replacement of traditional government-issued currencies, also known as fiat currencies.

So, what the difference between cryptocurrency and traditional currency? Fiat currencies or traditional currencies of countries around the globe are legal tender such as Dollar, Pound, Euro, Yen, Franc, etc. These fiat currencies gain their value and strength based on the fiscal performance of respective governments that issue them. All fiat currencies are centralised in that they are directly regulated and controlled by the government. All banks and banking institutions in these countries manage fiat currencies.

In a stark contrast, all cryptocurrencies are decentralised and not controlled by any entity be it the government or a company. At CoinRaver, we strive to help you learn everything you need to know about these digital crypto assets so that you can make better informed decision about buying a cryptocurrency.

In other words, a Cryptocurrency is a new-age digital currency that relies on cryptography to facilitate secure and easy online transactions between two individuals or entities. Many blockchain platforms such as Ethereum have their own native cryptocurrencies, called tokens, which can be traded for specific goods and services. But what is a blockchain? It is a decentralised technology used by many cryptocurrencies.

A blockchain is spread across numerous computers around the world to manage and record transactions. Notable for its secure nature, Blockchain technology can be used to buy goods and services, and even maximize trading profits on your investment portfolio.

Types of Currencies

Digital Currencies

Digital currency is a unified umbrella term that encompasses digital money that is used as a means of trade and exchange on the internet irrespective of geographical locations across the world. While digital currencies are not physical nor can be equated with banknotes and fiat currency coins, Digital currencies possess all the characteristics of true money. For instance, you can use them to buy or sell goods and services online and even transfer or exchange them like fiat currencies.

Virtual Currency

A Virtual currency is money that isn’t printed on paper or cast into metal. Virtual currencies exist only in the virtual world, however they can represent fiat currency. Usually popular as a means of transaction in bespoke virtual communities, virtual currencies exist as tokens and are unregulated nor issued by banks. In other words, a Virtual currency symbolises a monetary value that’s managed, controlled and distributed by private issuers for peer-to-peer (P2P) transactions.

While all virtual currencies are digital, some digital currencies are not virtual. The best examples of virtual currencies are Bitcoin and Ethereum.


Cryptocurrencies such as Bitcoin and Ethereum are a type of digital currency. However, cryptocurrencies operate without the meddling of central banks or intermediaries in a stark contrast to fiat currencies. Hence, cryptocurrencies are a trustworthy, safe and genuine means of exchange based on cryptography. Since the technology behind cryptocurrencies creates and analyzes protocols and algorithms, all the information or data can neither be interrupted nor modified by third parties. The usage of blockchains and  decentralized ledger systems ensure cryptocurrencies cannot be controlled by third parties.

All cryptocurrencies are unique in the sense they are built on different blockchains and offer something different. For instance, Bitcoin (BTC) is different from Ethereum (ETH) which is again world’s apart from Monero (XMR) and Cardano (ADA). The list goes on. Coinraver is full of helpful and informational guides on some of the most popular cryptocurrencies such as Bitcoin, Ethereum, Monero, Cardano, Litecoin, Dogecoin and many more Altcoins.

A Brief History of Cryptocurrency

There is a long and interesting story behind the evolution of Cryptocurrencies. A force to reckon with in the personal finance and technology sphere today, the story of Cryptocurrencies’ inception began as far as back in the 1980s. With the formulation of ideas of bit-gold and e-cash circulating in those times as a futuristic digital currency, the foundation for the creation of cryptocurrencies was laid down.

Various innovators were tirelessly working on creating a robust, verifiable and anonymous payment system spread over an extensive network and crafted through an advanced cryptographic process. However, it was only in 2008 that the world of fintech shook with the news of a white paper written by a mysterious person/entity who went by the name of Satoshi Nakamoto.

The white paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System” heralded the arrival of the world’s first ever cryptocurrency, Bitcoin, on the global financial scene. Nothing short of a revelation, Satoshi Nakamoto had plans to launch this new cryptocurrency that would redefine fintech and our lives forever. Incidentally, Nakamoto was the first person to initiate the first transaction done with a Bitcoin after sending an amount of Bitcoin to a friend in 2009.

How do Cryptocurrencies work?

All cryptocurrency transactions take place between peers via software known as Cryptocurrency Wallets that are used to transfer the requisite amount from one account (a public ledger address) to another. To safeguard their wallet account, users must have the password (private key) that can also be used to facilitate a transfer.

Through a process known as cryptocurrency mining, all crypto transactions are recorded on the public ledger system. While all transaction amounts are public (except in the case of privacy coins such as Monero, XMR), the sender’s identity remains encrypted.

All P2P transactions are first encrypted and then broadcast on the respective cryptocurrency networks before they are lined up and added to the blockchain also known as the public ledger. All crypto transactions have a unique set of keys, and the person/entity who has those set of keys owns all the cryptocurrencies associated with the keys. Since several transactions are added to the ledger simultaneously, the ledger technology is called “block” “chain” – or a chain of multiple transactions.


While Cryptocurrencies and the underlying blockchain technology are still in their nascent stage, they are a formidable force to reckon with immense potential. Just like the internet is a revolutionary invention that has made our lives easier, cryptocurrencies will transform the global financial landscape in the years to come.
