Brief introduction to Cryptocurrency

Cryptocurrency emerged in the early 21st century as a form of virtual money. It has been perceived as an innovative and safer means of transactions. Although it has become more popular and widely used for most internet transactions, many people are still in the dark about how this new form of currency works and what it actually entails.

A school of thought views cryptocurrency as a means for fraudsters, criminals, and terrorists to engage in financial transactions. This is due to the fact that it was untraceable and could be used to trade on the dark web. However, it is important to note that cryptocurrency is not untraceable as some companies have come up with innovative technologies capable of tracing cryptocurrency transactions.

Nevertheless, the current rise in the value of one of the major cryptocurrencies, Bitcoin, has proven cryptocurrency to be of feasible interest. This can be attributed to the positive publicity attached to the blockchain technology which backs up the cryptocurrency. Bitcoin and other cryptocurrencies are believed to have a positive effect on trading wallets and practices of recognized investors worldwide.

What is Cryptocurrency?

Before we dive into the meaning of cryptocurrency, it is necessary to note the meaning of “currency”.

Currency is any form of money accepted by the general public and issued by a government that is used for trading goods and services within or outside a nation. It is usually in form of paper bills and coins.

On the other hand, Cryptocurrency which is otherwise called “Crypto” is an encrypted and decentralized form of digital currency or legal tender. In simpler terms, a Cryptocurrency is a form of digital or virtual money. It can not be seen physically, it only exists virtually and can be used to trade goods and services. Transactions using crypto are confirmed and documented by a decentralized system using cryptography.

This is unlike any other forms of currency where the transactions and data are verified and tracked using a centralized system. Decentralized here means that the cryptocurrency is not controlled by a person or the government.

Types of Cryptocurrency

Currently, there are approximately more than 6,000 cryptocurrencies publicly traded. Here are some of the most popular cryptocurrencies;

Bitcoin (BTC)

This is the oldest and presently the most genuine of all cryptocurrencies. Currently, Bitcoin could be said to be the yardstick by which other cryptocurrencies are measured since all other forms of cryptocurrency market price are compared to the price of Bitcoin. The current market capitalization of BTC is over $600 billion.

BTC was founded by Satoshi Nakamoto and released in 2009. This is not his real name, however, no one has been able to find out his real identity. One of the features of Bitcoin is that it has a very low processing fee. It could be divisible to about 8 decimal points which are extendible.

Ethereum (ETH)

The Ethereum was released in 2015 and founded by Vitalik Buterin. It is the second-largest cryptocurrency among all the cryptos after Bitcoin by market capitalization. Currently, ETH has a market capitalization of over $196 billion.

ETH is an open-source blockchain with a smart contract capability. The platform operates on a native cryptocurrency called Ether. Ethereum was divided into Ethereum Classic (ETC) and Ethereum (ETH). ETH can be used as a program to create new tokens and blockchain applications.

Litecoin (LTC)

The Litecoin was created by a former Google employee, Charlie Lee. It was released in 2011. LTC is based on the Scrypt encryption algorithm, unlike the SHA-256. LTC currently, has a market capitalization of over $12.5 billion.

One major merit of Litecoin over Bitcoin is that it has the ability to process and confirm transactions faster than Bitcoin. Another advantage is that LTC uses an algorithm resistant to accelerated hardware mining technologies such as ASIC.

Ripple (XRP)

Ripple (XRP) was released in 2013 and was created by Chris Larsen and Jed McCaleb. XRP was designed to serve for a peer-to-peer debt transfer. It can not be mined like Bitcoin and other cryptocurrencies, this makes it trusted by banks and other payment networks.

The XRP currency exists as an independent coin. It is said to be the currency of other cryptocurrencies. A single XRP coin is made up of a million units called “drops”. The current market capitalization of Ripple stands at about $19.53 billion.

Features of Cryptocurrency

The rapid rise in the number of cryptocurrencies indicates that a considerable number of people use the currency to transact daily. It is however important to note the significant differences between digital or virtual currency and other types of currencies. These features are based on Bitcoin.

1. Virtual

Cryptocurrencies unlike other currencies do not exist as paper or coin. It is a virtual currency meaning that it exists only online. It does not have any physical form. Cryptocurrencies can only be used to trade and solve problems online.

2. Anonymous

Senders and receivers of crypto use a unique set of characters also known as a public key to send and receive money, the sender and the receiver will not know who owns the public key. The transactions are done anonymously on the network. Nevertheless, a transaction ID generated when the transaction is initiated can be used to track when and if the receiver receives the virtual money.

3. Inflexible

Every transaction carried out on the cryptocurrency network is recorded on the blockchain. This makes every crypto transaction irreversible. Trying to reverse it would involve the impossible task of altering the nodes in the blockchain.

This ensured that no one can move funds in a wallet except the owner of the private key. The history of every transaction can not be rewritten. However, it is possible to alter the transaction ledger but the cryptographic nature of the security makes it quite difficult to achieve.

4. Decentralized

According to Wikipedia, decentralization means “the process by which the activities of an organization, particularly those regarding planning and decision making, are distributed or delegated away from a central, authoritative location or group.” In other terms, this means that cryptocurrency is not controlled by any organization or government.

The decentralization of cryptocurrency makes it impossible for a group of persons to influence the currency to benefit them at the expense of others. it equally makes it impossible for an attack to be planned and carried out on the currency since it is much much expensive to attack, destroy or influence. Cryptocurrency is much more unlikely to accidentally fail since it relies on a network of varying factors.

5. Single Spending

The possibility of double spending is eliminated since cryptocurrencies can only be spent once. This means that you can not use one bitcoin to pay two or three different users for a single service or good.
