People’s working habits, communication styles, shopping habits, and even how they pay for products have all changed because of technological advancements. Companies and consumers are abandoning cash in favour of contactless payments, which are gaining popularity. With a quick wave of their mobile, customers can pay for products at digital registers. Now, a new type of payment system is gaining popularity that is cryptocurrency

Almost everyone has heard of Bitcoin by this point. It was the first cryptocurrency to gain mass acceptance, but others are emerging and becoming popular. There are over thousands of different forms of cryptocurrencies, with new ones being generated every day.

History of cryptocurrency

Cryptocurrency has had a long and winding journey over the last decade. Even though the public has only recently become aware of cryptocurrencies, there has been a considerable amount of work that has led to this stage. Cryptocurrencies have a long history, dating back to a time when Bitcoin did not even exist.

Which was the first-ever cryptocurrency?

Cryptographers had been experimenting with the concept of cryptocurrencies for decades before Bitcoin was created. The question of “what is cryptocurrency?” while the question remained unanswered at the time, it did not deter people from attempting to construct their own.. The most well-known of these attempts was made by Nick Szabo, a computer scientist who, in 1998, invented the Bit Gold cryptocurrency. Even though Bit Gold was never completely released, it is credited with laying the groundwork for Bitcoin.

What is cryptocurrency?

Cryptocurrencies, also known as “cryptos,” are touted as the future of finance. Cryptocurrencies can behave like real money—in certain ways, they are real money—but they exist in a digital form with no central authority to manage or govern them. A form of payment that can be used to exchange goods and services over the internet.

Many businesses have created their own currencies, known as tokens, that can be exchanged for goods or services. A cryptocurrency is a digital or virtual currency that uses cryptography to prevent counterfeiting and double-spending. Many cryptocurrencies use blockchain technology to build decentralized networks; a network of computers that enforces a distributed ledger.

How does cryptocurrency work?

A cryptocurrency is a digital, encrypted, and decentralized medium of exchange. Unlike the US dollar or the Euro, there is no central authority that regulates and maintains the value of a cryptocurrency. Instead, these functions are disseminated among cryptocurrency users through the internet.

Each coin is essentially a computer file stored in a digital “wallet” that can be accessed through smartphone apps or internet-connected devices. These files can be transferred (in whole or in part) from one person to another using blockchain technology.

While not all cryptos work in the same way, many of them rely on blockchain technology to ensure safe transactions.

What is blockchain technology?

A blockchain is a distributed log that keeps track of transactions. The name comes from the structure of the database, which consists of individual records (blocks) connected in a single list (chain). Blockchains are used to track cryptocurrency transactions like Bitcoin and have a wide range of other applications.

A blockchain is a decentralized, transparent ledger that stores transactions in code. Everyone who uses a cryptocurrency has their own copy of this book on a blockchain, which creates a single transaction record. – new transaction is logged by software when it occurs, and every copy of the blockchain is updated with the new information at the same time, ensuring that all documents are equal and accurate.

Types of cryptocurrency

Before cryptocurrencies were counted on fingers but with the digitalization of the market, these have grown and are uncountable. Today, there are thousands of different cryptocurrencies, each with its own collection of features and specifications. Cryptocurrency is basically categorized under tokens and coins.

  • Coins

Coins are cryptocurrencies that are based on their own blockchain network. Bitcoin (BTC) is the most well-known example, as well as the world’s largest cryptocurrency by market capitalization. Bitcoin’s native blockchain network is what keeps it going.

Litecoin (LTC) and Ethereum (ETH) operate similarly on their respective blockchains. The scale, rules, miners, and performance of these blockchains can vary.

Examples of common coins used are:

Bitcoin (BTC)

Ripple (XRP)

Dogecoin (DOGE)

Litecoin (LTC)

  • Token

Tokens are a type of cryptocurrency that do not have their own blockchain network. These cryptocurrencies, on the other hand, are based on a different blockchain. One of the many platforms available allows users to build digital tokens. Because of its support for smart contracts, Ethereum is one of the most common options.

Examples of commonly used digital tokens are:

Tether (USDT)

Basic Attention Coin (BAT)


Common types of cryptocurrency explained

The aim of digital currency is to serve as a medium of exchange. While there are several different forms of cryptocurrency, these are among the most well-known.

1.Bitcoin (BTC)

Bitcoin is a virtual currency that first appeared in 2009. It represents the ideas of Satoshi Nakamoto but still, the founders of bitcoin are a mystery. It is one of the most well-known currencies. It was released as open-source software in 2009. Bitcoin is a type of digital currency that can be defined as “cash for the internet.” Bitcoin is known as “digital gold”, has reigned supreme over all other cryptocurrencies.

One bitcoin equals $35,837.90.

2.Litecoin (LTC)

Litecoin is also known as “silver to Bitcoin’s gold,” Litecoin was developed as a split from Bitcoin in 2011, and it was released as a competitor in 2011 by Charlie Lee. Litecoin, like other cryptocurrencies, is an open-source, global payment network that is fully decentralized, which means it has no central authority. It was created to boost Bitcoin technology by reducing transaction times, lowering fees, and concentrating miners.

Recently Litecoin is equivalent to $197.27.

3.Ethereum (ETH)

Ethereum is a type of cryptocurrency that was created in 2015 as an open-source platform but is not developed on a peer-to-peer payment system. It was purposed by a programmer named Vitalik Buterin. Though the Ethereum blockchain is primarily used to monitor the ownership of digital currency transactions, it also hosts the programming code of any decentralized application, allowing developers to use it to pay for Ethereum network transaction fees and services.

1 Ethereum has a value of $2518.40.

4.Ripple (XRP)

Ripple is a utility coin conceived by Chris Larsen and Jeb McCaleb in 2012. It is not as much for individual users as it is for larger businesses and organizations who need to move vast sums of money around the world. Its blockchain platform is designed to make cross-border fiat currency transactions more effective. Ripple XRP, which has been closely linked to and funded by a variety of banks since its inception, is sometimes referred to as the ‘establishment’ cryptocurrency.

5.Dogecoin (DOGC)

Dogecoin is also a cryptocurrency like bitcoin and Ethereum. It was created in 2013 with the purpose to be faster but a fun alternative to bitcoin, as it is associated with a meme. Dogecoin has a larger number of coins in circulation than Bitcoin. One of the key reasons why investors expect to see future growth for this cryptocurrency, as it has gained popularity and reached the fifth position at market cap. Dogecoin is classified as an “inflationary cryptocurrency” since it appears to have no supply cap.

6.Stellar (XLM)

Stellar is an open-source currency and payment network. Stellar allows you to build, submit, and exchange digital representations of any type of currency, including dollars, pesos, bitcoin, and pretty much anything else. It is designed so that all the world’s financial systems can communicate across a single network. Stellar is much quicker, less expensive, and less energy-intensive than traditional blockchain-based systems. It is designed by Jed McCaleb, also a co-founder of Ripple.


NEO is formerly known as Antshares founded by Da Hongfei and Erik Zhan. It was created in 2014 but rebranded in 2017 with the purpose to create a smart economy. The term NEO is explained as digital assets, digital identity, and smart contracts, when all three elements come together, they form a smart economy.

8.Tether (USDT)

In the crypto world, Tether is the first and most well-known stable coin. A cryptocurrency based on blockchain format in which the crypto coins in circulation are backed by an equal sum of conventional fiat currencies kept in a specified bank account, such as the dollar, euro, or Japanese yen. Tether was created with the aim of providing users with stability, transparency, and low transaction fees by bridging the gap between fiat currencies and cryptocurrencies launched by Brock Pierce in 2014.


Cardano (ADA), is a cryptocurrency that is used to send and receive digital money. It claims to be the only cryptocurrency with a scientific theory and research-driven approach, as well as a more balanced and sustainable environment for cryptocurrencies.

That means it is subjected to extra scrutiny from scientists and programmers. Charles Hoskinson, who is also the co-founder of Ethereum, founded it.

Why do people use cryptocurrencies?

People can buy things with cryptocurrency. Cryptocurrencies, like gold or diamonds, are just another tradable product. One of the attractions of cryptocurrency was that it allowed you to send large sums of money anonymously, without the involvement of any government or organization. Cryptocurrency can also be used as an alternative to stocks and bonds as an investment. Bitcoin, the most well-known crypto, is a secure, decentralized currency that is referred to as digital gold. 

How widely cryptos are used?

Cryptocurrencies are not commonly used by companies or shops yet. However, a growing number of businesses are opting to accept cryptocurrencies as legal tender, with Tesla and Visa both announcing in March 2021 that they will accept them as a form of payment. Last October, the online payment service PayPal announced that its customers would be able to buy and sell Bitcoin.

Some firms, such as Google and Amazon, aim to create their own cryptocurrencies for transactions involving their own goods and services.

What is cryptocurrency mining?

Cryptocurrency mining is the method of verifying and adding transactions between users to the blockchain public ledger. Mining is also responsible for adding new coins to the existing circulating supply, and it is one of the key components that allows cryptocurrencies to act as a decentralized network without the need for a central authority, a peer-to-peer network can be established.

This is where the miners enter the picture. To check transactions in a block on the blockchain, miners use their computational power to solve complex mathematical problems. The miner who solves the problem and verifies all the transactions in a block is paid for their services. Proof of work (POW) is a technique for protecting a blockchain.

Reasons for cryptocurrency popularity

With cryptocurrencies, there is a modern way of transacting and storing value that is much superior to traditional fiat and gold. Cryptocurrencies outperform traditional currencies in several of the properties needed for safe money. There are multiple reasons why cryptocurrencies are gaining popularity.

  • One of the main reasons why the cryptocurrency is so popular around the world is that it has very low transaction fees. Many people assume that using cryptocurrencies to pay for items online is both sensible and secure.
  • Another important point for popularity why people gets involved with cryptocurrencies is the opportunity for benefit. Since the market has not cooled in recent years, investors are still profiting from cryptocurrencies.
  • People believe in cryptocurrencies since they are not linked to any national governments. As a result, cryptocurrencies have the capacity to maintain their stability. Cryptocurrencies are seen by some investors as a good way to safeguard their assets.
  • Cryptocurrency is too easy to get through the simple and customer-friendly process through reliable sources which have helped in its growth.
  • This is now seen as the future of money by many analysts. The whole process of blockchain tends to change the world’s perception in many ways regarding transparent trading.
  • Cryptocurrency provides safer transactions in the era of cybersecurity. It is quite difficult to keep your data and assets safe during traditional payment methods, but its security has let it gain popularity among people who do not want to show their assets.
  • Cryptocurrencies are also simpler to move and split than traditional currencies. Rather than carrying pounds of gold or large wads of cash, cryptocurrencies are simply bits of data used to keep track of transactions and values. These can cross any boundary without being censored and can also be split into fractions of a penny if desired.

Is cryptocurrency a good investment?

One of the most frequently asked questions is whether cryptocurrency is a decent investment. This is a difficult question to answer because it could be a good investment or it could be a bad one. Cryptocurrency has the potential to make you extremely wealthy, or it has the potential to cause you to lose your income. Cryptocurrency is an excellent investment, especially if you want to gain direct exposure to digital currency demand.

How safe is cryptocurrency?

To be frank, there are certain risks associated with cryptocurrency that are not present in conventional markets such as bonds and stocks. Crypto exchanges, for example, have been particularly vulnerable to hacking and other illegal activity. Naturally, these security breaches have resulted in substantial losses for many investors whose digital currencies have been stolen.

Scams and frauds have also become increasingly popular in the crypto world. Since some hypesters promise investors incredible returns that they cannot deliver. When these ventures fail, investors who fall into this pit normally lose money.

How to invest in cryptocurrency?

Investment in any form requires a lot of homework to save your hard-earned money. For cryptocurrency invest wisely by observing these simple facts.

  • The crypto market, like the stock market, is highly unpredictable, meaning that prices fluctuate wildly. Limit your investment to 5-10% of your annual revenue, if possible.
  • Right now, there are several cryptocurrencies on the market, each with a different price point. However, it is not advisable to hop on the bandwagon and try to invest in five separate small cryptocurrencies. To choose the best crypto coin, you will need to do a lot of research. Bitcoin is currently the world’s largest cryptocurrency, as well as the most trusted, ahead of Ethereum, Ripple, Litecoin, and Binance Coin.
  • Selecting the right cryptocurrency exchange matters. It is essentially a marketplace where you can buy, sell, and store your crypto properties. These crypto exchanges are specifically designed to handle cryptocurrencies and their unpredictable existence, like how banks and other financial institutions are designed to lend money, store money, and provide mortgages.
  • Before you can own cryptocurrency, you will need a place to keep it. A cryptocurrency wallet is a name for that location. A cryptocurrency wallet is a piece of software that stores private and public keys and interacts with different blockchains to enable users to send and receive digital currency while also keeping track of their balance. 

After all these above steps are followed finally, you must pay to buy them. Credit cards, bank transfers, and even cash are the most popular and agreed payment methods for purchasing cryptocurrency. You will need to pick a trustworthy website that supports the payment method you want to use because different websites support different payment methods.

Advantages and disadvantages of cryptocurrency

Digital currencies are gaining a competitive advantage because of increased industrialization and technological participation. The main advantages and drawbacks of Cryptocurrencies are mentioned below.


  • Any cryptocurrency transaction is encrypted, secure, and virtually anonymous. No one, including banks, would be able to spy on your financial activities or obtain your personal information from your account history. Your latest transactions can only be viewed by you. Thus, giving you secured and confidential transactions.
  • Sending money across borders is one of the most popular uses of cryptocurrencies. With the help of cryptocurrency, a user’s transaction fees are reduced to a minimal or zero-sum amount. It accomplishes this by obviating the need for third-party authentication, such as that provided by VISA or PayPal. There will be no need for any extra processing fees as a result of this.
  • Cryptocurrencies have always maintained their position as the best option for transactions. Cryptocurrency transactions, whether international or domestic, are lightning-fast. This is since the verification takes very little time to complete because there are very few obstacles to overcome.
  • Any currency’s governance and maintenance are critical to its development. Developers/miners are rewarded for storing cryptocurrency transactions on their hardware by receiving the transaction charge. Since the miners are compensated for their work, they keep transaction records correct and up-to-date, ensuring the cryptocurrency’s credibility and decentralizing the records.
  • Inflation has caused the value of many currencies to depreciate over time. Almost every cryptocurrency is published with a fixed sum at the time of its launch. The sum of any coin is specified in the source code; for example, there are only 21 million Bitcoins available in the world. As a result, as demand rises, its value rises as well, keeping pace with the market and, in the long run, preventing inflation.
  • Many currencies, including the US dollar, European euro, British pound, Indian rupee, and Japanese yen, can be used to purchase cryptocurrency. One currency can be transformed into another by trading in cryptocurrencies, through different accounts, and with low transaction fees, using various cryptocurrency wallets and exchanges.
  • One of the key advantages of cryptocurrency is that it is mostly decentralized. Unlike fiat currencies, which are dominated by the government, decentralization helps keep the currency monopoly free and in check so that no single organization can determine the flow and value of the coin. This, in turn, keeps it safe and secure.


  • Some cryptocurrencies can only be bought and sold in a limited number of fiat currencies. This forces customers to convert these currencies first into one of the major currencies, such as Bitcoin or Ethereum, and then into their desired currency through other exchanges. Just a few cryptocurrencies have been impacted. This adds additional transaction costs to the process, costing you the money you do not need.
  • Since cryptocurrency transactions are so private and safe, it is difficult for the government to track down or monitor any user based on their wallet address. Still in the past cryptocurrencies have been used for illegal transactions.
  • The coin cannot be recovered by the sender if there is a conflict between the parties involved, or if funds are sent to the incorrect wallet address by mistake. Many people may use this to defraud others of their capital. Since there are no refunds, one can easily request one for a transaction for which the goods or services were never delivered.
  • Cryptocurrency mining necessitates a lot of computing power and electricity, making it a very energy-intensive process. This whole process is one of the major issues in increasing the emission of carbon footprint.
  • The designers wanted to make source code that was practically untraceable, solid hacking protections, and impenetrable authentication protocols.
  • Putting money in cryptocurrencies, rather than actual cash or bank vaults, would be better. However, if a user’s private key is lost, there is no way to retrieve it. The wallet will be kept secure, as will the number of coins inside. Thus, resulting in financial loss.


It will take time to master the world of cryptocurrencies, so do not put too much pressure on yourself to become an expert right away. Finding out how to optimize the potential of your virtual coins—whether you want to use them for trading or everyday transactions—takes time, practice, and continuous learning, just like any other ability.
