Introduction to Cryptocurrencies – Understanding the Basics of Digital Currencies

Cryptocurrencies have been continually current in the past years, and that might possibly place it amongst the most thrilling active and effective investments.  Beginning with mere and only Bitcoin currency up to thousands of ‘altcoins’ it has drastically changed the perspective of what kind of money people accept. Though still relatively young and unconventional, the author of one of the possible first texts on the subject does not describe the usage of cryptocurrencies but tries to define what cryptocurrencies are and why they are here and what they are trying to achieve.

What are Cryptocurrencies?

Cryptocurrencies are considered as digital or virtual currencies which employ the use of cryptography in its security and are developed on a network basis on the concept of ‘blockchain’. Cryptocurrencies are not funded institutions like legal tender, they tend to be decentralized and are chiefly administered on a blockchain that fosters unprejudiced transactions through a peer-to-peer system and do not require endorsement by acknowledged institutions such as banks.

How do Cryptocurrencies Work?

Yet, at the core of all these cryptocurrencies is the concept of blockchain. A blockchain is a database that is synchronized in every computer by performing an action known as ‘mining’. Transaction information is segregated by blocks, and each block is incorporated sequentially into the chain; time-stamped records of each transaction can thus be easily tracked.

All cryptocurrencies make use of the cryptographic algorithms to make the completed transactions more secure and determine the creation of more currency units. 

Bitcoin was created in 2009 by a person or a group whose identity is still unknown and is an anonymous writer named Satoshi Nakamoto and is the first crypto currency that has similar popularity and acceptance. Although they have been replaced by many thousands of other ad hoc cryptocurrencies usually referred to as altcoins with their own distinct properties and applications. The most widely recognized altcoins include ether, ripple, litecoin, Cardano, and others.

Why do Cryptocurrencies Matter?

Bloomberg highlights that virtual currencies have some benefits over fiat money: They make transactions seamless with secure, and permissionless, borderless characteristics that allow people to send and receive payments across the world. Also, they may act as an inflation/ currency devaluation hedge, since many cryptocurrencies have a limited supply; as opposed to ‘fiat’ currency which is created in the midst of central authority discretion.

Cryptocurrencies have been the most popular application of a new technology called blockchain, which has immense potential beyond finance. It can also transform various sectors like supply chain, health care, and balloting where accurate record-keeping is essential since it has been proved to offer reliable solutions to those sectors.

Challenges and Risks

Nevertheless, it is noteworthy to clarify the fact that cryptocurrencies have their weaknesses and threats as well. There are many potential drawbacks and challenges, with one of the main ones being high price fluctuation, where prices can change sharply within days. That is a challenge that frequently affects the cryptocurrency industry in the form of security breach and hack which results in a loss of millions of dollars worth of digital currency.

The fourth challenge key to understanding is the regulatory risk, political and legal actions, whereby governments around the world are struggling to determine how to control cryptocurrencies.Furthermore, the cost incurred in mining these currencies, especially the cryptocurrencies that are based on the proof-of-work consensus algorithm such as BTC, have also been considered, most especially with regards to the environmental impact.


Digital currencies are a new and unique phenomenon in the financial markets, disrupting the central bank issued money system. As seen with the impact that cryptocurrencies can have on the financial systems and the rest of the world, the topic is set to continue being a subject of discussion and discussion in the coming years. It is crucial to have a general grasp of the fundamentals revolving around digital currencies in order to be able to work within this fairly new category of markets and make proper use of its potential.actions and ownership of the units of the present cryptocurrency. The records of transactions are kept in blocks that are registered in the large decentralized ledger known as a blockchain: individual blocks are generated after new sales are made through mining, which involves solving computational problems to authenticate the transactions.
