Cryptocurrency is an Internet that is secured by encryption. that is one of the two words crypto means cryptocurrency and currency mean digital currency or money. the first and most famous cryptocurrency is bitcoin.

In this article, we will fully explain the nature and application of cryptocurrency and suggest that you follow us to the end of this article.

Cryptocurrency, also known as digital currency, is digital money contained in a data unit (called a token or coin) that one can store in an online digital wallet.

The idea behind cryptocurrency is to provide a means of exchanging currency with limited supply, independent of a central authority, such as a bank or government. Cryptocurrency is transmitted electronically; therefore, there is no physical coin or banknote and no third party entity is involved in its creation or transfer.

The Federal  Commission

The Federal Trade Commission (FTC) has shared some useful facts about cryptocurrency on its website:

  •  Encrypted currencies, such as US bank deposits, are not insured by the government.
  •  According to the FTC, the value of a cryptocurrency can change from hour to hour.
  • An investment that may be worth thousands of US dollars today may only be worth hundreds of dollars tomorrow.

If this amount decreases, there is no guarantee that it will increase again. Unlike credit and debit cards, which have legal protection in the event of a mistake, Cryptocurrency has no legal protection, and payments are usually non-refundable.

Once you have paid with a cryptocurrency, you can only get your money back if the seller returns it.

Since cryptocurrency is a subset of digital currency, we suggest that you read the digital currency article in the digital-currency signal.

What is cryptocurrency?

What is cryptocurrency?
Cryptocurrencies are digital exchange tools created

Cryptocurrencies are digital exchange tools created and used by individuals or private groups. That’s not regulated by national governments. so it is considered an alternative currency.

They are intermediaries of financial exchange that exist outside the confines of government monetary policy. Bitcoin is the most prominent type of cryptocurrency and has been widely used since its inception.

However, there are hundreds of cryptocurrencies, and more are coming to market each month. Cryptocurrency uses cryptocurrency protocols or very complex code systems that encrypt sensitive data transmissions to secure their exchange units.

In other words, crypto at the beginning of the word cryptocurrency refers to various encryption algorithms and cryptographic techniques that protect these inputs, such as elliptic curve encryption, public-private key pairs, and hash functions.

Cryptocurrency developers create these protocols based on the principles of advanced mathematics and computer engineering, which make it impossible to break them and thus copy or counterfeit protected currencies. These protocols also disguise the identity of cryptocurrency users and allow transactions and financial flows to individuals or groups that do not attribute anything special.

How do digital currencies work?

Cryptocurrency, digital money, or currency is a new asset and capital that allows users to make their online payments quickly anywhere in the world without the need to go directly to the bank and without the supervision of any government.

Known as the most valuable and popular cryptocurrency in the digital currency market, Satoshi Nakamoto, the anonymous creator of Bitcoin, stated in the Bitcoin White Paper that the goal of creating digital currencies and Bitcoin is a peer-to-peer electronic cash system. In this way, intermediaries are eliminated and financial transfers are made as soon as possible and without commission.

Many marketers see the use of digital currencies as a way to fight corruption and oppressive governments. Because one of the goals of the formation of this technology and market is the complete elimination of governments from financial transactions with a completely unknown function.

You do not need anything more than an internet connection to start trading digital currencies, which is the first difference between using a traditional banking system and a cryptocurrency market. In addition to this model of digital currency applications, many governments around the world do not agree with their prevalence and have even repeatedly banned the use of cryptocurrencies, as in China.

Governments oppose

One of the reasons governments oppose digital cryptocurrencies is that they can be used for illegal activities such as money laundering and gambling.

Some countries, such as the United States, have taxed their people for cryptocurrency transactions and have made it mandatory for them to use their digital currency exchange services. Making such regulations can, to some extent, prevent money laundering and misuse of cryptocurrencies.

furthermore, note that the price of digital currencies fluctuates a lot. In the first 5 years of bitcoin’s formation, it was worth less than $ 1,000, but in 2017, it grew significantly to $ 20,000. In 2018, it dropped to less than $ 5,000, and finally, in 2021, it reached its dream price of more than $ 60,000.

It may seem difficult to buy many goods using digital currencies at the moment, but over time the number of companies using bitcoins is increasing. You can also use online tools and digital currency calculators to calculate the current price of Bitcoin.

Decentralized control

Cryptocurrency is known as decentralized control. The supply and value of cryptocurrencies are controlled by the activities of users and the very complex protocols contained in the code, not the informed decisions of central banks or other regulators.

Meanwhile, the activities of miners are very important for the stability and performance of currencies. Miners are cryptocurrency users who use a lot of computing power to record transactions, newly created cryptocurrency units, and transaction costs.

What is the difference between a currency code and a digital currency?

The question for many people may be, what is the difference between a currency code and a digital currency? Simply put, a currency code is a type of digital currency. Digital currency is a collection that includes a variety of currencies such as virtual currency, national digital currencies, and cryptocurrencies. So it can be said that every currency code is a digital currency, but not every digital currency is necessarily a currency code.

History of cryptocurrency

History of cryptocurrency
Cryptocurrency as a theory existed long before

Cryptocurrency as a theory existed long before the introduction of the first digital alternative currencies. Early proponents of cryptocurrency agreed on the use of advanced mathematical and computer science principles to address the practical and political shortcomings of traditional Fiat currencies. Knowing the history of cryptocurrency helps us to know whether the concept of cryptocurrency and digital currency is new. We first look at the basics and then the virtual currencies before the advent of bitcoin.

Technical basics

The technical foundations of Cryptocurrency go back to the early 1980s when an American cryptographer named David Lee Chaum invented the Blinding algorithm, which still survives in modern web-based cryptography. This algorithm made possible the exchange of secure and unchangeable information between the parties and the ground for the transfer of future electronic currency. This algorithm was also called Blinded Money.

DigiCash appears

In the late 1980s, David Cham hired a handful of cryptocurrency enthusiasts to commercialize the concept of hidden money. After moving to the Netherlands, he founded a for-profit company called DigiCash, which generated currencies based on the blinding algorithm.

Unlike Bitcoin and other modern currency cryptocurrencies, DigiCash control was not decentralized. Cham had a monopoly on supply control, similar to the monopoly of central banks on Fiat currencies.

DigiCash initially dealt directly with individuals, but the Bank of the Netherlands stopped it. In the face of the central bank ultimatum, DigiCash agreed to sell only to authorized banks and severely limit its market potential. Microsoft later turned to DigiCash for a potentially lucrative partnership that allowed early Windows users to buy in their currency, but the two companies could not agree on terms, and DigiCash went bankrupt in the late 1990s.

Wei Dai

Around the same time, a software engineer named Wei Dai published an article on b-money. B-money was a virtual currency architecture that incorporated many of the key cryptocurrencies of modern currencies, such as anonymous identity protection and decentralization. However, b-money was never used as a medium of exchange.

Shortly afterward, Cham co-founder Nick Szabo developed a currency code called Bit Gold, which was notable for its use of the Chinese blockchain system, which is the basis for most modern currency codes. BitGold, like DigiCash, has never been considered and is no longer used as a medium of exchange.

Virtual currencies before bitcoin

After DigiCash, research and investment in e-financial transactions became more common, including PayPal, which has gained popularity over the past 10 years, and many DigiCash followers, such as Russia’s WebMoney, have appeared in other parts of the world. In other words, DigiCash paved the way for the emergence of other digital currencies.

E-gold enters

In the United States, the most popular virtual currency in the late 1990s and 2000s was known as e-gold. E-gold was created by a company of the same name in Florida. The company acted as a buyer of digital gold. Customers or users sent their old jewelry and coins to the e-gold warehouse and received digital e-gold (an ounce of gold).

E-gold users could then trade their assets with other users or exchange their e-gold for US dollars.

Active account

At its peak in mid-2000, e-gold had millions of active accounts and traded billions of dollars annually. Unfortunately, relatively weak security protocols have made e-gold a popular target for hackers and phishing scammers, exposing its users to financial losses. In the mid-2000s, many e-gold trading activities were legally suspicious; In other words, flexible legal policies made it attractive for money laundering activities and small Ponzi schemes. The platform came under legal pressure in the mid-to-late 2000s and finally shut down in 2009.

Bitcoin and the modern cryptocurrency boom

Bitcoin is known as the first modern cryptocurrency. In early 2009, Nakamoto released Bitcoin to the public, and a group of enthusiastic fans began exchanging and extracting currency. In late 2010, the first of dozens of similar cryptocurrencies emerged, including Litecoin. The first public bitcoin exchanges took place at the same time.

In late 2012, WordPress became the first major merchant to accept payment in Bitcoin. (online retailer), Expedia, and Microsoft also entered the field. Dozens of merchants now view bitcoin as a legal payment method.

Important concepts of cryptocurrency that you need to know

Cryptocurrencies are digital or virtual currencies that can be worked with under a cryptographic system. These currencies allow you to trade online without the presence of any intermediary, and therefore the cost and time of such activities compared to doing things using regular currencies is significantly reduced.

The term Crypto refers to a variety of cryptographic methods, algorithms, and techniques that provide security in all matters related to digital exchanges and transactions. Therefore, it can be concluded that the basis of cryptocurrencies is their security.

In such transactions, no one other than the parties to the transaction is aware of this activity, and information about it will not be leaked anywhere in any way. Currency cryptocurrencies can be extracted or exchanged at a digital currency exchange, but there are still restrictions on trading with them.

Even the most popular and well-known currency cryptocurrency, such as Bitcoin, is still not widely used in transactions. Recently, Tesla has made it possible to purchase the company’s cars using Bitcoin.

However, it seems that the pervasiveness of such transactions, in which the currency code is used instead of the usual currency, will not happen soon. Of course, this issue has not been able to increase the popularity of these currencies in any way.

Cryptocurrencies are becoming more and more popular with incredible speed and more and more people are becoming interested in investing in this field. So far, we are fully acquainted with the concept of cryptocurrency. In this part of the article, we intend to explain some important concepts in this area.


Blockchain in cryptocurrency is a platform that records and stores all previous transactions and activities, as well as confirms the ownership of all currency units at a specified time. As the whole history of cryptocurrency transactions to date, blockchain has a limit, in other words, it includes a limited number of transactions that increase over time.

Copies of the Chinese blockchain are stored in each node of the cryptocurrency software network. Cryptocurrency software networks are the same decentralized server network farms that are managed by computer experts or miners, who continuously record and verify cryptocurrency transactions.

The cryptocurrency transaction is not technically finalized until it is added to the blockchain, which is usually done within minutes. Once the transaction is finalized, this process is usually irreversible. Unlike traditional payment processors, such as PayPal and credit cards, most cryptocurrencies do not have something called a refund, although some newer cryptocurrencies have basic repayment features.

Units are not available for use by either party during the delay between the start of the transaction and its finalization. Instead, they are somehow kept safe for specific purposes; thus, blockchain avoids double the cost or manipulation of cryptocurrency code to duplicate similar currency units and send them to multiple recipients.

Private Keys

Each cryptocurrency holder has a private key that authenticates them and allows them to exchange units. Users can create their private keys in two ways. One way is to use integers formatted with a length of 1 to 78 digits or use a random number generator to create a private key. With a key, users can create and spend cryptocurrency. Without a key, the holder cannot spend or convert their cryptocurrency.

This is a vital security feature that reduces theft and unauthorized use, but it is still stupid. Losing a private key is tantamount to putting your wallet in a trash can with your own hands;

In other words, you can create another private key and restart the cryptocurrency, but you cannot recover the resources protected by your old lost key; Therefore, smart cryptocurrency users protect their private keys and usually store them in various digital locations (which, of course, are not generally connected to the Internet for security purposes) and analog (paper).


Cryptocurrency is an Internet currency that is secured by encryption. that is one of the two words crypto means cryptocurrency and currency mean digital currency or money
crypto Currency users have wallets with unique information

crypto Currency users have wallets with unique information that confirms users as temporary owners of their units. While the private key verifies the cryptocurrency transaction, the digital currency wallet reduces the risk of theft for unused units.

Wallets used in cryptocurrency exchanges are somewhat vulnerable to hacking. For example, Mt.Gox was a Japanese-based bitcoin exchange that went bankrupt a few years ago because hackers systematically emptied more than $ 450 million worth of bitcoins exchanged through servers.

Wallets can be stored in the cloud, on an internal hard drive, or on an external storage device. Regardless of how you store your wallet, it is strongly recommended that you have at least one backup. Note that backing up your wallet does not copy and duplicate the actual cryptocurrency units, but only copies their history and current ownership.


Miners act as the custodians of cryptocurrency trading records for cryptocurrency communities and indirect judges of currency values. their use a lot of computing power.

Their work is often done on private server farms belonging to mining companies, consisting of tens of people. They use highly technical methods to check the completeness, accuracy, and security of the currency blockchain.

The scope of operations is not dissimilar to the search for new prime numbers, which also requires extraordinary amounts of computational power.

Miners periodically create new copies of the blockchain, add previously unverified transactions that did not exist in previous versions of the blockchain, and effectively complete these transactions. Each transaction that is added is known as a block.

Blocks include all transactions made since the creation of the latest new version of the Chinese block.

The term miners refer to the fact that miners’ work generates capital in the form of new cryptocurrency units. Each newly created blockchain version has a two-part monetary reward: a fixed number of newly extracted cryptocurrency units and a variable number of existing units collected from optional transaction costs paid by buyers (usually less than 1%) Of transaction value.

It is worth noting that at one time, miners could generate a lucrative business to extract currency cryptocurrencies simply by spending on electricity sources and powerful hardware, but today mining operations are not possible for those interested in doing so without investing thousands of dollars in professional equipment.

What is the transaction fee?

What is the transaction fee?
transaction fees do not accrue to sellers

Although transaction fees do not accrue to sellers, miners are allowed to prioritize fee-loaded transactions over fee-free transactions when creating new blockchains, even if the first transaction is unpaid. This motivates sellers to look for more commissions because they make money faster, so commissions are usually more common.

Although a new version of the Chinese blockchain is completely unpaid in terms of previously unconfirmed trading theory, this rarely happens in practice.

Through the instructions in the source code, the cryptocurrency automatically adapts to the amount of extraction power it generates to create new versions of the blockchain. As extraction power increases, it becomes more difficult to make copies of the Chinese block, and vice versa. The goal is to keep the average distance between creating new fold blocks at a predetermined level. For example, this number is 10 minutes for Bitcoin.

Limited supply

Although mining operations periodically generate new cryptocurrency units, most cryptocurrencies are designed to have a limited supply, which is the main guarantor of their value. In general, miners receive fewer new units over the new China block over time. Eventually, miners only receive transaction fees for their work, although this has not yet happened in practice and may not happen for a long time.

However, if the current trend continues, observers predict that the last bitcoin unit will be mined sometime in the mid-22nd century. Thus, cryptocurrencies have a limited supply and are more like precious metals such as gold than Fiat currencies, which theoretically have unlimited resources.

Cryptocurrency market

Cryptocurrency market
cryptocurrencies are traded through crypto markets

The vast majority of cryptocurrencies are traded through crypto markets. These are virtual places for exchanges. The crypto market contains the most important information about tokens, prices, volumes, and market trends. The cryptocurrency market is created not only for experienced investors but also for beginners who want to start their adventure with cryptocurrencies.

How does the cryptocurrency market work?

Currency cryptocurrencies set the exchange rate for both Coin and Token. Cryptocurrency rates usually depend on the performance of sellers and buyers. Other factors can affect the price. Currency cryptocurrencies allow you to buy and sell digital currencies.

In principle, operations in these markets are similar to ordinary stock exchanges. The difference is that in the stock market, investors buy and sell assets, stocks, or derivatives to take advantage of exchange rate fluctuations.

However, in cryptocurrency markets, traders use cryptocurrency pairs to take advantage of highly volatile exchange rates.

Is it illegal to use the currency code?

Bitcoin became the most widely used currency in the United States, Japan, the United Kingdom, Canada, and other developed countries as of February 2020. In emerging markets, the legal status of bitcoin is still changing dramatically.

China has severely restricted bitcoins without penalizing bitcoin holdings. India has banned banks from trading in bitcoin, and the overall status of the country’s currency code is unclear. In general, bitcoin laws in each country should be considered separately.

It is important to note that in cases where Bitcoin is legal, most of the rules for other assets also apply to Bitcoin. For example, tax laws that trouble most people. For tax purposes, bitcoin is considered more of an asset than money. Bitcoin is not generally considered a legal tender.

The attention of the world’s largest companies to this fledgling industry

Large companies such as Facebook, Yahoo, Google, and Amazon have a special look at this industry, which we will briefly describe below:

Facebook launches Coin

Since December 2017, rumors have been circulating that Facebook wants to enter the cryptocurrency industry. The rumor started when, during the cryptocurrency wave, David Marcus, former PayPal chairman and chairman of Facebook and WhatsApp messaging platforms joined the board of Coinbase.

However, he then resigned in May 2018 to focus entirely on integrating cryptocurrencies with Facebook and avoiding conflicts of interest. Facebook registered a new company called Libra Networks on May 2 in Geneva, Switzerland. The Libra project focuses on creating a currency code that allows Facebook users to shop online.

Yahoo recently announced a new exchange

Yahoo; owns 40% of a Japanese exchange called Taotao, which it bought in April 2018 at an estimated 2 billion yen. It seems that after the re-profit of the Japanese cryptocurrency holders, this platform will enter the market just in time. The Japanese exchange has seen new accounts increase by up to 200%.

Initially, the platform will be open for bitcoin and Ethereum trading, as well as for margin trading Litecoin, Ripple, and Bitcoin Cash.

Google launches new currency-related search tools

With over 3.5 billion daily searches, Google is one of the most widely used search engines in the world. The platform is currently working on a way to display digital currencies in a more user-friendly way by displaying relevant information including top stories and other similarly suggested digital currencies when the user searches.

Currently, this interface only works for a few of the most popular virtual currencies such as Bitcoin, Ethereum, and Ripple. However, there are plans to include a much wider range of currencies in the future. Google has also made big data and search algorithms available to users to generate information from large blockchains such as Bitcoin and ‎Ethereum.

Amazon registers the cryptocurrency domain

Amazon has registered many new cryptocurrency-related domains, including

  •, and

While no official announcement has been made by Amazon about the purchase of these domains, it does raise considerable speculation that Amazon is preparing to move into the cryptocurrency market. In addition, the company currently uses a digital currency called Amazon coin. Although this coin is not a cryptocurrency and acts more like a gift card, it could be a test case for a future blockchain support solution.

Advantages and disadvantages of digital currencies

Advantages and disadvantages of digital currencies
are aware of cryptocurrency’s advantages and disadvantages.

Cryptocurrency fans are not able to use digital currencies in all cases, and without a doubt, investing in this field is not suitable for everyone.

Before making any decision about entering the cryptocurrency market to earn money and invest, be sure to be aware of its advantages and disadvantages.

What is the advantage of digital currency?

Digital currency is not controlled by any government. Therefore, there is no imposition of sanctions and interference of the rulers in it. This can be mentioned as one of its best advantages. Especially for a country like Iran, the possibility of financial transfers without the need for government approval is a valuable feature.

No bank can change the value of this currency by implementing interventionist policies. These currencies are easy to use. Its security is high due to its lack of physicality, and it also leaves the management of a person’s assets to him.

Apart from these issues, due to the existence of the law of supply and demand, digital currencies have created a very profitable environment that is not under the control of governments like the stock market. After seeing the necessary training, different people enter this market and earn money.

Digital currency has many advantages over Fiat currencies and is, therefore, more popular daily.

Increase in GDP:

The government can earn significant revenue by extracting digital currencies and selling them to foreign countries. Also, if there is a clear law for extracting bitcoins, the government can earn a lot of tax revenue from miners.

Market advantages from the fans’ point of view:

In theory, you can buy and sell digital currencies without the supervision of a bank, broker, or government, which allows you to avoid paying fees and have more privacy. The price of bitcoin has skyrocketed in the new year, and some investors think that shortly bitcoin, like gold, will become a fixed element with an investment outlook.

Proponents of her case have been working to make the actual transcript of this statement available online. Proponents of her case have been working to make the actual transcript of this statement available online.

Disadvantages of using digital currency

Unfortunately, the use of cryptocurrencies has many commercial disadvantages. Here are some of them:

You may lose your virtual wallet, so you will lose your currency and capital. There is a lot of volatility in the digital world. The value of digital currencies such as bitcoin can change significantly, so some people do not think it right to convert their real money into bitcoin.

The cryptocurrency market is not regulated by the Financial Conduct Authority (FCA). So there is no law to protect your capital and transactions.

If companies or consumers transfer their capital from a currency code to a new currency or stop using digital currencies altogether, they may lose value and become completely worthless.

Cryptocurrency exchanges are vulnerable to cyber attacks, which can lead to a complete loss of your capital.

Encrypted currency can be vulnerable to fraud. Scammers often use platforms such as Facebook, Instagram, and Twitter to deceive people into these investments.

Disadvantages of the market from the perspective of opponents:

Opponents of this market, on the other hand, believe that digital currencies are a speculative investment and have sharp price fluctuations, which always puts a lot of risk on the market. If you are looking to get rich through digital currency, choosing the right coin is very difficult.

Due to the lack of regulation by a central authority, the future of the cryptocurrency market is very uncertain. China recently banned digital currencies, and the United States may do the same.

Another disadvantage of digital currencies is how they are stored in wallets, if users forget or lose their password, they will lose all their assets. Also, many countries have a tax on cryptocurrency transactions, which contradicts the main purpose of its formation, and in the end, many goods can still not be bought with cryptocurrencies.

Limited supply preserves the value of cryptocurrency

Limited supply preserves the value of cryptocurrency
currency codes are more similar to precious metals

In most cryptocurrencies, the source code indicates how many units can always exist. In this way, the currency codes are more similar to precious metals than to Fiat currencies. Cryptocurrencies, like precious metals, are less prone to inflation, a problem that users of Fiat currencies struggle with.

This leads to a reduction in government currency monopolies

Currency cryptocurrencies provide a reliable alternative to exchanges outside the direct control of national banks, such as the US Federal Reserve and the European Central Bank. This is especially appealing to those who are concerned that a small reduction (printing of central bank money by buying government bonds) and other forms of expansionary monetary policy will lead to long-term economic instability.

In the long run, many economists and political scientists expect world governments to incorporate cryptocurrency, or at least aspects of cryptocurrency, such as limited supply protocols and authentication, into Fiat currencies. This could potentially allay some cryptocurrency proponents’ concerns about the inflationary nature of fiat currencies and the inherent insecurity of physical cash.

Strictly protect privacy

Privacy and anonymity have been and continue to be the main concerns of early cryptocurrency advocates. Many currency users use aliases unrelated to any information, account, or stored data that they can identify. Although skilled members of the crypto community can identify users, the cryptocurrency of new currencies (after Bitcoin) has additional layers of protection that make the task much more difficult.

It makes it difficult for governments to impose strict financial penalties

When citizens in repressive countries protest against their governments, governments can easily freeze or seize their domestic bank accounts or reverse transactions in local currency. This is especially worrying in authoritarian countries such as China and Russia, where wealthy people who are heavily pressured by the ruling party face serious financial and legal problems of dubious origin.

Unlike central bank-backed fiat currencies, cryptocurrencies are virtually safe from authoritarian games. Cryptocurrency funds and transaction records are stored in various locations around the world, making it very difficult for the government to control (even assuming international cooperation).

It is generally cheaper than traditional electronic transactions

Blockchain concepts such as private keys and wallets effectively solve the problem of double-spending and ensure that new currency codes are misused by tech-savvy scammers who can duplicate digital funds.

They are not placed. Cryptocurrency security features eliminate the need for a third-party payment processor such as Visa or PayPal to validate and validate any electronic financial transaction. Cryptocurrency transaction fees are usually less than 1% of the transaction value, compared to 1.5% to 3% for credit card and PayPal payment processors.

Barriers and costs of international transactions are lower

The behavior of cryptocurrencies with international transactions is no different from domestic transactions. Transactions are either free or at a nominal transaction cost, no matter where the sender or receiver is. This is a huge advantage over international transactions involving Fiat currency, which almost always has certain costs that do not apply to domestic transactions, such as an international credit card or ATM fees.

Direct remittances can be very expensive, with costs sometimes exceeding 10% or 15% of the amount transferred.

Lack of regulation facilitates black market activity

Probably the biggest regulatory concern about cryptocurrency is its ability to facilitate illegal activities. Many online black and white market transactions are made with bitcoins and other cryptocurrencies. For example, in 2014, the notorious Dark Web site Silk Road used Bitcoin to facilitate illegal drug purchases and other illegal activities. Currency cryptocurrencies are also increasingly the most popular tool for money laundering.

The same strengths that make it difficult for governments to track cryptocurrencies allow criminals to operate with relative ease. It should be noted, however, that the founder of Silk Road is now behind bars thanks to a lengthy investigation by the DEA.

It has the potential for tax evasion

Because cryptocurrencies are not regulated by national governments and are usually out of their direct control, they are naturally attracted to tax evaders. Many employers pay their employees bitcoins and other cryptocurrencies to avoid paying tax on their salaries and help their employees avoid paying income tax. Also, online retailers often accept cryptocurrencies to avoid liability. Income tax and sales should be avoided.

There is a possibility of losing money due to data loss

Users who store their private keys on physical storage devices will incur an irreparable financial loss if the device is lost or stolen. If the server is physically damaged or disconnected from the World Wide Web, even users who store their data with a cloud service may be harmed (this is likely for servers in countries with tight Internet control, such as China).

Prices fluctuate a lot and there is a possibility of manipulation

Many cryptocurrencies have relatively few prominent units concentrated in the hands of a handful of people (mostly currency makers and their close associates). These holders effectively control the resources of these currencies and by manipulating them cause the cryptocurrency value of the currencies to fluctuate. However, even the most widely traded cryptocurrencies are subject to price fluctuations, for example, the value of bitcoin multiplied in 2017 and halved in the first few weeks of 2018.

It can often not be exchanged for Fiat currency

In general, only the most popular cryptocurrencies allow direct exchange with Fiat currency. The rest do not have a dedicated online exchange and therefore cannot be exchanged directly for fiat currencies. Instead, users must encrypt Fiat currencies before converting them to more common currencies such as Bitcoin. As bitcoin transactions increase, so does the demand for some of the lesser-used cryptocurrencies, and thus their value.

There is no possibility of refund and repayment

Cryptocurrency miners indeed act as quasi-intermediaries in cryptocurrency transactions, but they are not responsible for arbitrating disputes between the parties to the transaction. This judgment violates the decentralization of cryptocurrency. This means that if you have been cheated in a cryptocurrency transaction, you have no one to appeal to. For example, you pay in advance for a product you never receive.

Although some of the new currency codes try to solve the repayment problem, the solutions remain incomplete and largely unproven.

In contrast, traditional payment processors and credit card networks such as Visa, MasterCard, and PayPal often intervene to resolve buyer-seller disputes. Their repayment policies are specifically designed to prevent seller fraud.

Cryptocurrency extraction operations leave adverse environmental effects

Cryptocurrency extraction is a very expensive operation. Among the cryptocurrencies, the largest consumer is bitcoin.

According to Ars Technica, bitcoin mining consumes more electricity than the whole of Denmark. Cryptocurrency experts acknowledge that mining operations pose a serious threat to the environment at current growth rates.

Can currency codes be used for online and offline payments?

Bitcoin as a currency has come a long way since it was said that 10,000 bitcoins would be enough for two pizzas. Several different online stores and retailers have created a space for payment with cryptocurrencies. The Overstock online retailer as well as the Newegg e-shop accept bitcoin payments for purchases, and the Expedia travel site allows users to use BTC for some hotel reservations. There is also a pizza site called that is specifically designed to buy cryptocurrency pizzas.

Online platforms are inherently more receptive to currency cryptocurrencies; however, some physical sites have turned to cryptocurrencies.

Including some KFCs and subways around the world. Starbucks’ partnership with the Intercontinental Exchange Inc., which launched the Bakkt cryptocurrency integration system, has left people wondering if the day will come when they will buy Starbucks with Bitcoin.

How secure is cryptocurrency?

Currency tokens are usually created using China Blockchain technology. Blockchain describes how transactions are recorded in the blockchain. This is a very complex and technical process, but the result is a digital space of cryptocurrency trading that is difficult for hackers to manipulate. In addition, transactions require a two-step authentication process. For example, you may be asked to enter a username and password to start a transaction.

Then, you may have to enter an authentication code that is sent to your mobile phone via text. Of course, this does not mean that currency codes can be hacked.

The hackers hacked Coincheck for $ 534 million and BitGrail for $ 195 million in 2018. According to Investopedia, these two were the biggest cryptocurrency hacks of 2018.

Cryptocurrency examples

Bitcoin is the first and most valuable cryptocurrency in the world The use of cryptocurrency has been very popular since it was released Bitcoin.

Although the exact number of active currencies is not fixed and the value of the currencies is very volatile, the overall market value of the active currency cryptocurrency is generally upward.

Hundreds of cryptocurrencies are exchanged at any given time. The cryptocurrencies we cite here are characterized by factors of stability, strong user activity, and relatively high market capitalization (in most cases over $ 10 million, although valuations are variable).


Bitcoin is the most widely used cryptocurrency in the world and is generally considered to be the mainstream. Its market value and individual unit value are consistently shorter (by a factor of 10 or more) than the next most popular cryptocurrency. Its planned supply limit is 21 million bitcoins. Bitcoin is increasingly seen as a legal medium of exchange. Many well-known companies accept bitcoin payments, although most convert bitcoins into US dollars before receiving their funds.


Light Coin, released in 2011, uses the same basic structure as Bitcoin. Key differences include a higher planned supply limit (84 million units) and a shorter time to create a target block (2.5 minutes). The encryption algorithm is also slightly different. LightCoin is often the second or third most popular cryptocurrency based on market value. There are many differences between Bitcoin and Light Coin, which we suggest you read about by visiting its page.


Released in 2012, Ripple has a consensus ledger system that dramatically speeds up transaction verification and blockchain creation (there is no official target time, but the average is a few seconds). Ripple is also easily converted to other cryptocurrencies by exchanging domestic currency, which can convert Ripple units into US dollars, yen, euro, and other common currencies. However, critics say the network and Ripple code are more vulnerable to manipulation by skilled hackers and may not offer the same protection as the anonymity of bitcoin-derived currencies.


Launched in 2015, ‎Ethereum has made significant advances in the basic Bitcoin architecture.

‎Ethereum, in particular, uses smart contracts that apply to transaction performance. In this way, it forces the parties not to violate their agreements, and in case of violation of the agreement by one of the parties, there are mechanisms for repayment.

Although smart contracts represent an important step towards resolving the issue of refunds in cryptocurrencies, it remains to be seen whether they will be able to solve the problem completely. You can read more about everything you need to know about ‎Ethereum in the Academy Partner article.


The Dodge Coin, named after the Shiba Inu dog internet jack, is a change in Lightcoin.

The time it takes to create a blockchain is shorter (one minute) and there are many more coins in circulation. Its makers met their target of 100 billion units mined by July 2015. This currency code is known as supply restriction; Dodge Coin is, therefore, a significant test in cryptocurrency inflation and experts are closely monitoring it to see how different its value path is in the long run from other cryptocurrencies.

Can cryptocurrency become more popular in the future than a physical currency?

Theoretically, it is possible, but it probably takes years and requires a lot of technical, economic, regulatory, and legal issues before it can be implemented.
