What Is Cryptocurrency?

Digital or virtual currency, also called cryptocurrency or crypto, is any form of currency that is available exclusively in electronic form and uses cryptography to verify and make secure transactions. 

Cryptocurrencies operate independently without a central issuing or regulating authority. Without this; the digital system doesn’t rely on banks to verify transactions.

What Is Private Key Of Cryptocurrencies?

The private key proves ownership of cryptocurrencies and is necessary for carrying out transactions as digital entries to an online database. And these cryptocurrency transactions are recorded in a public ledger.

Secure your digital cash and do not lose your private keys, otherwise, you’ll lose your cryptocurrency. Crypto owners store their holdings safely in digital wallets.

What is Crypto Mining?

By saying crypto mining, we mean validating cryptocurrency transactions on a blockchain network and adding them to a distributed ledger. It is important to note that crypto mining prevents the double-spending of digital currency on a distributed network.

When to Use Cryptocurrencies?

Everything is going paperless and cryptocurrency is the newest and most promising addition to the digital payment sector.


Nowadays there are lots of merchants, both online and offline, who accept Bitcoin as a form of payment. For example, big online retailers like Newegg and Overstock and lots of small local shops, restaurants, and bars accept cryptocurrency.
You can even use Bitcoin to pay for flights, hotels, apps, computer parts, or jewelry. There are Gift Card websites that accept more than 20 different cryptocurrencies and through these, you can buy anything.
Ripple, Ethereum, Litecoin, etc, are not as popular as Bitcoin is. However, Apple has authorized at least 10 different cryptocurrencies as viable forms of payment.
We should mention that some marketplaces like OpenBazaar and Bitify accept cryptocurrencies only.

Using For Payments

Accepting cryptocurrency as a form of payment may attract new customers to a business, as the interest in cryptocurrencies is only increasing.
Simply put a sign by your cash register to make your customers aware that your business accepts cryptocurrencies.

Hardware terminals, and wallet addresses through QR codes or touch screen apps can serve as means of accepting the payments.
In the US Bitcoin and other cryptocurrencies are considered to be convertible virtual currency and accepting them as payment is equivalent to accepting cash gift cards or gold.


Almost all of us have heard stories of becoming millionaires through crypto investments. But remember, cryptocurrencies are high-risk investments as their market value fluctuates very fast, unlike any other investment. Moreover, there is a risk that they will be outlawed in some jurisdictions.
The most secure way of storing your cryptocurrency is an offline wallet on a hard drive. Your coins will stay safe and you will have full access to your assets.

Please note that your tax report includes both your profit and loss. The taxation rules for cryptocurrency are different in every country. For example, in the US the IRS has said that Bitcoins or any other digital currency is to be taxed as property and not currency.

Advantages of Cryptocurrencies

Cryptocurrencies have their advantages, so you should know about them before starting to invest:

  • Client autonomy or independence is the essential draw of cryptocurrency. This monetary form allows clients to self-rule over their own cash without managing middlemen like a bank or government.
  • Crypto transactions are discrete as they are considerably less promptly connected to individuals personally.
  • The users are free from the customary financial charges related to fiat monetary forms. 
  • The expenses of executing are extremely low since cryptocurrency exchanges have no middle-person organizations or government contributions. 
  • Unlike banks, the crypto markets are always open. Crypto might be the best way to generate returns outside of normal working hours.

Disadvantages of Cryptocurrencies

Alongside advantages, cryptocurrencies have disadvantages as well. It’s better to be aware of them and make conscious decisions:

  • Understanding cryptocurrency can take time and effort if you’re not a digital native. You’ll need to dedicate some time to truly understand the pros and cons of investing in cryptocurrency because investing in something you don’t really understand is itself a risk.
  • Cryptocurrencies can be extremely volatile. The price of a cryptocurrency can both spike to dizzying highs and crash to terrifying lows. It is not the best bet for stable returns. 
  • The concept of cryptocurrency emerged with the publication of a white paper on Bitcoin only in 2008, while stock markets can look back on centuries of history. And we can’t say what will happen to cryptocurrencies in the future.
  • Crypto has serious scalability issues that slow the rate at which transactions can be processed.
  • Newer investors are more vulnerable to hacking, phishing, and all the other attempts to gain control by malicious means. Or, if you lose the private key that lets you access your coins you will lose your holdings.
Disadvantages of Cryptocurrencies

The Most Popular Cryptocurrencies

Here’s a list of the 10 most popular cryptocurrencies with the highest valuation. Take into account that the name of the blockchain platform may be different from its digital currency.


Bitcoin is the most popular kind of crypto in the market. Nowadays, Bitcoin is recognized as a serious asset and is limited to 21M coins. It has the biggest network effect because of having the most secure blockchain and the best developers working on the project.

The mission of bitcoin was an effort by Satoshi Nakamoto to stop the scams that the money changers feed the public.

Bitcoin relies on blockchain technology, a decentralized public ledger that contains a digital record of every Bitcoin transaction. The basic system of cryptography and consensus (i.e., peer-to-peer) verification is the foundation of Bitcoin and most forms of crypto today.

Proof-of-work (PoW) is a complex, time-consuming process for bitcoin miners who use powerful computers to verify blocks of transactions and generate more bitcoins. The transactions are logged permanently on the blockchain. This helps to validate and secure each bitcoin and the network as a whole. 

A vast amount of energy is required for creating Bitcoin. And it has raised concerns about environmental pollution.


Ethereum is a blockchain network, which was created to enable the network’s users to create, publish, monetize, and use applications (called “dApps”). The native Ethereum currency is Ether (ETH), which was developed as a form of payment on the Ethereum platform.

ETH is also generated using a proof-of-work system. Unlike Bitcoin, there is no limit to the number of ETHs that can be created. 

Cardano (ADA)

The complicated PoW calculations and high electricity usage required for mining coins like Bitcoin aren’t necessary in the case of Cardano, as it relies on proof-of-stake (PoS), potentially making its network more efficient and sustainable.

Cardano’s cryptocurrency is called ADA, after Ada Lovelace, who was a mathematician.

Cardano supports smart contracts, and ADA allows users to participate in the network’s operation. Each phase of the Cardano building is anchored by its research-based framework and peer-reviewed insights, which have helped establish its scholarly reputation.

Binance Coin (BNB)

Binance Coin (BNB) is a cryptocurrency token that is used as a medium of exchange on Binance (one of the world’s biggest cryptocurrency exchanges). It was first built on the Ethereum blockchain.

BNB was created in 2017 and allowed traders to get discounts on trading fees on Binance. Now it can also be used for payments, travel booking, entertainment, online services, and even financial services.


Tether is marketed as a “stablecoin,” and its value is pegged to a fiat currency – in this case, the U.S. dollar.

Tether offers stability, transparency, and lower transaction charges to users. This cryptocurrency can be used by investors who want to avoid the extreme volatility of the crypto market.

Tether is pegged to the U.S. dollar but there is no guarantee provided by Tether, Ltd. for any redemption of tethers; i.e., tethers cannot be exchanged for U.S. dollars.


Solana is a blockchain platform and its cryptocurrency is known as Sol. It was one of the more volatile currencies.

Solana’s smart contract technology is based on the programs that run on the platform according to preset conditions (like paper contracts, but without the middlemen). Solana was also behind the “Degenerate Ape Academy,” a non-fungible token (NFT) that was launched in August 2021.


The terms XRP and Ripple are sometimes used interchangeably, but they are different. Ripple is a global money transfer network, and XRP is the crypto that works on the Ripple network. You can buy XRP as an investment, a coin to exchange for other cryptocurrencies, or a way to finance transactions on Ripple.

Unlike other cryptocurrencies, XRP can’t be mined, and only 100 billion XRPs are existing. On the Ripple network participating nodes conduct a poll to verify transactions. Thus we may say that XRP transactions are faster and cheaper than Bitcoin.


The first joke cryptocurrency, Dogecoin (pronounced dohj-coin), was launched in 2013 as a way to poke fun at Bitcoin. When Elon Musk expressed his positive opinion on Dogecoin in 2019, Dogecoin’s profile was raised as a legitimate cryptocurrency.

Dogecoin runs on a blockchain network using a PoW system. And the number of coins that can be mined is unlimited.

Polkadot (DOT)

Polkadot’s cryptocurrency is called dot. It was established in 2020 and has become one of the bigger networks in a relatively short time. Polkadot uses two blockchains – the main one is the “relay” network, where transactions are permanent, and the other one is the parallel network of user-created blockchains, called “parachains.”


USD Coin (USDC) runs on the Ethereum blockchain and several others. It is pegged to the U.S. dollar, and a USDC is worth one U.S. dollar, making it a stable form of exchange.

The stablecoin USDC makes transactions faster and cheaper. As of June 2021, there were 24.1 billion USDC in circulation.
