Cryptocurrency, which is a decentralized digital currency, is based on blockchain technology.  While you may be familiar with Ethereum and Bitcoin, there are over 5,000 other cryptocurrencies available.
Although you can use cryptocurrency to purchase regular goods and services it is not as popular as other investments like stocks or precious metals, many people still invest in crypto.
Satoshi Nakamoto, the founder of Bitcoin (BTC), introduced blockchain technology to the globe in 2008, and Bitcoin is still the most popular cryptocurrency. However, there are thousands of cryptocurrencies available today, including Bitcoin Cash and Ethereum. Altcoins are alternative to Bitcoin.


How does Cryptocurrency work?

Cryptocurrency functions in the same way as PayPal or credit cards except that you exchange digital assets for goods, services, and not dollars. To transact with cryptocurrency, you need to exchange currency with a peer through a digital wallet (also known as a crypto wallet). A cryptocurrency wallet lets you transfer funds from one account into another. A private key, also known as a password, is required to perform a transaction. The private key functions in the same manner as a bank card. You can have multiple keys and control all funds that are sent to them. Transactions are kept on a public record, which records the totals of transactions without disclosing the identities.

What is Mining?

It is the process of verifying transactions with cryptocurrency. Although it requires a large amount of computing power, complex algorithms, and can result in reward coins, tokens, or transaction fees, people who are successful in mining can make a living from solving problems.

What is the difference between Cryptocurrency and Traditional Currency?

You need to know two components that make cryptocurrency unique: cryptography (blockchain) and cryptography (cryptography).

Blockchain technology: A blockchain database keeps track of all transactions and totals for cryptocurrency. It stores data as “blocks”, or “chained”, that are linked together and arranged in chronological order. Blockchain does not have a central authority, unlike traditional currency. It is a distributed ledger that can be accessed by all cryptocurrency owners. To create new blocks or validate transactions, the system uses processes such as “proof of work” or “proof of stake”.
Cryptography: Cryptography is the process of making the blockchain safe. Cryptographic codes are also known as “hashes” link blocks together making them impossible to hackers. These hashes work in a similar way to secure passwords. A user can create one easily, but it’s nearly impossible for someone else to guess it.

What should you know about cryptocurrency markets?

Decentralized cryptocurrency markets do not have central backing or issuing them. They are distributed across a network. But cryptocurrencies can be purchased and sold on exchanges, and then stored in “wallets”.
Contrary to traditional currencies, cryptocurrency is a digital record of ownership that can be shared on a blockchain. A user can send cryptocurrency units to another person by sending them to their digital wallet. Once the transaction has been verified through mining, it is now considered final. This is how new cryptocurrency blocks are created.

What drives cryptocurrency markets?

The supply and demand of cryptocurrency markets are governed by each other. They are also decentralized so they don’t have to deal with many of the political and economic concerns that traditional currencies face. Although there are still many uncertainties surrounding cryptocurrency, these factors can have a major impact on their price:

Supply: The total amount of coins and their rate of release, destruction or loss
Market capitalization is the sum of all coins and the perceptions of its users.
Press: How cryptocurrency is presented in the media, and how much coverage it gets
Integration refers to the ease with which cryptocurrency integrates into existing infrastructure, such as e-commerce payment systems.
Events of importance: Major events like regulatory updates, security breaches, and economic setbacks

What is Crypto Mining?

Crypto mining is the process of creating new cryptocurrency coins by solving complicated mathematical equations. The blockchain is a distributed ledger that records details of an investment in cryptocurrency. The transaction is only complete when a “miner”, or someone who validates the transaction, confirms it as valid. Once this is done, the transaction will be visible on the blockchain and is completed.
The verification process requires miners to solve complicated equations. To solve the problem, they must race against each other. The first to complete a transaction is paid a fraction as a fee. Each successful transaction results in new coins being put into circulation.

Types of cryptocurrency

Bitcoin is the original cryptocurrency, and all other currencies are collectively known by the term “altcoin” (a combination of “alternative coin”) Although it is difficult to choose the best cryptos, Bitcoin and other large altcoins are among the top choices due to their security, privacy, and scope of functionality.
There are many kinds of cryptocurrency. The most popular are:

Bitcoin (BTC)

Bitcoin is a well-known cryptocurrency. It was originally created as open-source software in 2009. Satoshi Nagamoto was the author.
Bitcoin allows peer-to-peer transactions to be transparent using blockchain technology. All users can see these transactions, however, they are encrypted by the blockchain algorithm. The transaction can be seen by everyone, but only the owner of the Bitcoin can decrypt it. Each owner is given a “private key” to decrypt the transaction.
Bitcoin does not have a central authority like a bank. Bitcoin users have control over money sending and receiving, which allows anonymous transactions to occur around the globe.

Dogecoin (DOGE)

Dogecoin was once considered the “original meme coin”. The coin’s price soared in 2021, causing a lot of controversies. Some major companies accept the coin as payment, including Kronos and the Dallas Mavericks. SpaceX is an American aerospace manufacturer that Elon Musk owns.
Two software engineers, Jackson Palmer and Billy Markus, created Dogecoin in 2013. According to reports, Palmer and Markus created Dogecoin as a joke in response to the wild speculation surrounding the cryptocurrency market.
DOGE’s price reached an all-time high at $0.71 on Saturday Night Live, when Elon Musk was due to make an appearance. Dogecoin’s market capitalization was $34 billion as of November 2021. One DOGE is worth $0.26. This makes it the ninth-largest cryptocurrency.

Ethereum (ETH)

Ethereum, a cryptocurrency type that was developed using blockchain technology, was launched in 2015. Ethereum blockchain not only tracks the ownership of digital currencies but also runs the program code of any decentralized app, which can be used by developers to pay for transaction fees on the Ethereum network.

XRP (Ripple)

XRP, a digital currency, is based on RippleNet’s digital payments platform. Ripple built it. It is designed to allow financial institutions to make digital payments around the world and reduce transaction costs associated with cross-border transfers. XRP can also be used to extend short-term credit lines.


Tether, also known as a stable coin or a currency linked to a fiat currency, in this case, the U.S. dollars, is what we refer to as a stable coin. Tether combines the advantages of cryptocurrency (such as no financial intermediaries) and the stability of a currency that is issued by a sovereign country (versus the volatility inherent in many cryptos).

Ethereum Classic (ETC)

Ethereum Classic is an Ethereum version. It runs smart contracts on the same decentralized platform. Smart contracts are applications that work exactly as they were programmed and can be accessed without any downtime, censorship, or fraud. It provides a value token known as “classic ether” that is used to pay users for their products and services.

How secure is cryptocurrency?

The blockchain is more secure the more transactions that are publicly recorded. Cryptos are vulnerable to cyberattacks and exit scams as well as theft and money laundering.
For instance, Initial Coin Offerings (ICO) and fake coin launches have been reported.
You can also lose your wallet and delete your Bitcoins. This will cause them to be lost forever.
Due to speculative trading, cryptocurrencies can become volatile. As with any commodity trading, there are risks associated with investing in them.

How widely accepted is cryptocurrency?

Cryptos can be traded just like gold or diamonds. Many people prefer cryptos to traditional currencies. This is because they aren’t controlled or regulated either by governments or banks and transactions are anonymous.
Although some countries have banned Bitcoin usage, others are open to the idea. For instance, the Bank of Singapore indicated it may use Bitcoin as its currency store to replace gold.

Businesses and shops aren’t yet widely using cryptocurrency. A growing list of companies is choosing to accept cryptocurrency as legal tender. Tesla, the carmaker, and Visa, the credit card company announced in March 2021 that they will recognize them as a payment method. AirBaltic, meanwhile, announced it was expanding the list of cryptos that are accepted by its airline.
PayPal, an online payment service, also announced last October that it will allow its customers to use Bitcoin for purchase and sale.
Google and Amazon have plans to issue their own cryptos for transactions involving products and services that they offer.

How to safely store cryptocurrency 

A cryptocurrency wallet is a software that stores your private and public keys, allows you to send and receive digital currency, manage their balance, and interact with different blockchains. To manage and protect your crypto assets, you will need a cryptocurrency wallet.
A hardware wallet, sometimes known as “cold storage”, is widely recognized as the best way to store cryptocurrency. The hardware wallet is backed by security experts. It keeps your private keys offline so that your crypto can’t be accessed by anyone except the owner of certain access codes.

Can I get cryptocurrency for free?

To own a cryptocurrency, you don’t have to purchase it. You can also earn cryptocurrency by solving cryptographic equations using computers which is known as mining. This involves validating transaction records and adding them to the blockchain.
Also, some cryptocurrencies such as Bitcoin have a finite supply. This means there is a maximum amount of coins that can ever be circulated. Others, such as Ethereum, have no maximum limit but limit how many coins can be produced each year.

What are the advantages of cryptocurrency?

Easy transactions

Transaction fees are a significant cost when you do business with legal professionals or brokers. There are many paperwork, brokerage fees, commissions, and other requirements that must be met. The middleman is eliminated when you use cryptocurrency. The transactions would be done one-to-one over the secure network. Transparency would ensure that transactions are transparent and audit trails can be established more easily.


The main advantage of cryptocurrencies is their ability to be decentralized. Many cryptocurrencies can be controlled by developers who use them, those with a large amount of the coin, or corporations that develop it before it goes on the market. Decentralization keeps the currency free of monopoly and in control. It will not be possible to determine its flow or value, which is a major advantage over fiat currencies that are controlled by governments.

Low transaction fees

You can see the transaction fees for each transaction on your bank statement. The fee could be very high if you perform a lot of transactions per month. Data miners would get their compensation from cryptocurrency networks, so there would not be any transaction fee or charge at all. You must pay for the service if you are giving up the responsibility to maintain your crypto wallet. The transaction fees for cryptocurrency transactions are lower than traditional financial systems.

Private and secure

Cryptocurrencies have been concerned about security and privacy. Different mathematical puzzles are required to create the blockchain ledger. These puzzles can be difficult to decode. This makes cryptocurrency more secure than regular electronic transactions. Cryptocurrencies offer greater security and privacy. They use pseudonyms and are not connected to any user accounts or stored data that could be associated with a profile.

Disadvantages of cryptocurrency

There is no refund or cancellation

The sender cannot retrieve the coin if there is a dispute or someone sends funds to an incorrect address. Many people might use it to scam others. There are no refunds.

Vulnerable to hackers

While cryptocurrencies seem very secure, exchanges do not seem to be as secure. To figure the user ID, most exchanges keep users’ wallet data. Hackers can often steal this data, giving them access and control over many accounts.
These hackers are able to transfer funds quickly from these accounts once they have access. Bitfinex and Mt Gox have been hacked in the last few years. Bitcoins have been stolen in thousands of dollars and many more. Although most exchanges are now highly secured, there’s always the possibility of another hack.

Consumption of high amounts of Energy

Mining cryptocurrency requires a lot of computation power and electricity input. This makes it extremely energy-intensive. Bitcoin is the main culprit. Bitcoin mining requires powerful computers and lots of energy. It is impossible to do this with ordinary computers. Many of the largest Bitcoin miners live in countries such as China, which uses coal to generate electricity. This has greatly increased China’s carbon footprint.
