Cryptocurrencies are virtual payment systems with their monetary units, all transactions that are protected cryptographically (encrypted). As a rule, systems are decentralized and do not have a single regulatory authority or processing center. The term “cryptocurrency” was introduced in April 2011 after publication in the American magazine Forbes about the first widespread system of this kind – bitcoin (bitcoin, from the English bit – unit of information “bit” and coin – coin).

Principle of Operation

“Digital wallets” are the tangible homes for digital currency. Using blockchain distributed database technology, the system typically encrypts data about user accounts and bitcoin exchange transactions between them. Volunteers and users run the system’s program on their computers to keep it running.

Bitcoin and the majority of cryptocurrencies function autonomously. Users who run apps typically serve as the sole source of virtual currency emissions through “mining.” A small sum of virtual money is delivered to these users in exchange for utilizing their computers’ resources or processing power.


The most common cryptocurrencies

As of January 20, 2022, the capitalization (the total value of all those on the market) of Bitcoin, the most popular cryptocurrency, is $796 billion. There are about 2-3 thousand different cryptocurrencies in the world. The most popular also include:

  • Capitalization of Ethereum, – $374 billion, unit cost – $3.1 thousand;
  • Capitalization of BNB, – $78.9 billion, unit value – $475;
  • Capitalization of Tether, – $78.3 billion, price fixed – $1;
  • Capitalization of USD Coin, – $46 billion, fixed price – $1.

The government’s first coin was the Petro. It was created on February 20, 2018, in response to the economic catastrophe and hyperinflation of the bolivar, the official currency of Venezuela. Only a few people in Venezuela or anywhere else utilized Petro despite its value being tied to the price of a barrel of Venezuelan oil.

How Is Cryptocurrency Used?

A blockchain is a decentralized public ledger that records all transactions involving cryptocurrencies. Cryptocurrency holders update this ledger.


Mining generates cryptocurrency, or coins, by solving complex mathematical problems utilizing computational power. Brokers also make it possible for regular people to buy cryptocurrency. After that, people can store and spend their cryptocurrency money using cryptocurrency wallets.

Regarding digital money, cryptocurrency is a type of digital money that lets people send and receive value without going through a government bank. This eliminates the need for a central authority or a third party that can be trusted to handle the transfer of value.

Even though Bitcoin has been around for a while, banks are still getting used to all the buzz about blockchain technology and cryptocurrency.

On the other hand, they could grow further and be used in future stock, bond, and other financial asset deals.

An Example of Trading Cryptocurrencies

Regarding cryptocurrencies, only a few stand out as being well-known and essential. This list includes the ones that everyone knows and loves:

The Bitcoin

Bitcoin, the first cryptocurrency, is still widely used today. Bitcoin was launched in 2009. Whoever or whatever created it is still a mystery, as they are using the pseudonym Satoshi Nakamoto.


Ether (ETH) is the platform’s money and the product of Ethereum, a blockchain launched in 2015. This digital money is second in popularity.


Litecoin is a cryptocurrency that is comparable to Bitcoin but has the advantage of embracing new technology more quickly, allowing for more transactions per second and faster transaction times.

The Ripple

Established in 2012, Ripple is a decentralized database system. Banks and other financial organizations commonly employ it to keep tabs on more than just cryptocurrency transactions.

Altcoins refer to the remaining cryptocurrency options apart from Bitcoin.

How to buy cryptocurrency?

The question of how to buy digital currency securely may be on your mind. 

Choose a platform

As a first step, choose a platform to work with. Either a regular broker or a cryptocurrency exchange tailored to your needs are available to you.

Standard Brokers. These online brokers facilitate purchasing and selling cryptocurrency and other financial assets: stocks, bonds, and ETFs. These platforms typically offer lower trading fees but fewer cryptocurrency features.

Cryptocurrency Exchanges

There are many cryptocurrency exchanges, each offering a variety of cryptocurrencies, wallet storage, interest-bearing account options, and more. When comparing platforms, paying attention to the cryptocurrencies traded, fees, security features, storage and withdrawal options, and educational resources is recommended.

What Is Mining Cryptocurrencies

The word “mining” is being used increasingly because of the rising popularity and use of cryptocurrencies, especially Bitcoin. This word is translated from English as “mining.” About cryptocurrencies, the term refers to using computer resources to process payment system transactions by creating new blocks, ensuring their security, and generating new records in a shared database.

To put it simply, mining is the extraction of cryptocurrency. These most often bitcoins are explained by their most significant demand and popularity in the market at present. In essence, the computer’s owner, using its resources to operate the virtual payment system, collects and processes information about ongoing transactions with cryptocurrency. This activity is necessary to ensure that transactions are carried out, their security is provided, and the entire peer-to-peer decentralized system functions smoothly. The greater the number of miners and computer resources involved in the process, the more reliable and stable the system’s operation.

How Does Cryptocurrency Mining Work?

The process of mining cryptocurrency is quite entertaining. The participants’ equipment in the “digital race” searches for a specific number from vast information. These are not some abstract tasks, but in particular, confirmation of transactions (transfers) of funds within the system. These tasks are formed into blocks. The decryption of information in a block is carried out using the selection method – this is why the system needs such gigantic computing power. Even with excellent hardware capacity, the miner needs help finding such a number.

This is why single systems are combined into pools (mining pools), a server that distributes the tasks of finding a number among all participants. Everything in this system is very transparent and understandable. Any transaction can be tracked. The only information that remains hidden from prying eyes is the data of wallet owners.

Crypto Mining Equipment

Simple mining schemes that were effective several years ago required the following equipment: 2-3 video cards, a motherboard, a processor, RAM and permanent memory, and a power supply. Naturally, to connect to the system, it was necessary to install the appropriate freely available software. Electricity is a vital resource consumed in large quantities during the mining process.

Mining Programs

Many different programs have been developed that can be used for mining cryptocurrencies. The choice of a specific product is determined, first of all, by the capabilities of the user’s computer. The effectiveness of different programs will differ for different configurations and computing power.

The simplest mining option is to use a cloud pool. In this case, the capacities of a specialized company are rented or purchased along with the software installed on them. However, the cost of renting or buying resources is relatively high in most cases.

Which Cryptocurrency To Choose For Mining?

Finding the answer to which electronic currency is most profitable to mine is tricky. The fact is that the cryptocurrency market was formed only in recent years. It is constantly changing, and new types of virtual money appear regularly. All this makes more or less accurate forecasting of the further development of the market situation extremely unlikely.

However, every year, it becomes increasingly difficult for individual miners to profit by mining the most popular cryptocurrencies, such as bitcoins or ether. Therefore, it makes sense to pay attention to equally popular types of virtual currency.

Mining Prospects

It is essential to understand that with the growing popularity of virtual money, making a profit from mining becomes more problematic. This is explained by an increase in the number of participants and the arrival of significant financial resources in this market segment. As a result, mining individually becomes simply unprofitable.

Another potential danger is the fact that some cryptocurrencies that have emerged recently do not provide for the possibility of mining. Such virtual money includes, for example, Ripple or IOTA, which have shown stable growth in recent years.

How Much Can You Earn?

It is impossible to give an unambiguous answer to the question about potential earnings from mining. This is explained by the fact that it is determined taking into account many difficult-to-predict factors, including the current exchange rate of a particular cryptocurrency and the dynamics of its change, the size of investments in mining, the number of participants in the “mining” process, etc.

It is necessary to understand the following: the growth of the total capitalization of the virtual money market leads to the fact that the average payback period for investments is constantly increasing. For example, until recently, investments in Bitcoin mining were returned within 2-3 months, bringing further profits, and the entry threshold was relatively low. Today, to start effectively mining the most popular cryptocurrency, a severe amount of funds is required, amounting to at least several thousand dollars. In this case, the payback period is 9-12 months, sometimes even longer.

Is Mining Possible Without Investment?

Currently, it is tricky to talk about serious mining without investments. At the same time, many companies providing cloud mining services are trying to increase the number of clients through various advertising campaigns. In some cases, users are offered the opportunity to “mine” cryptocurrency for free for a certain period.

As the world continues to explore and adapt to the potentials and challenges of cryptocurrencies, it is clear that they have introduced a paradigm shift in how we conceive and engage with financial systems. The ongoing evolution of this technology underscores the importance of continued research, innovation, and responsible adoption to shape the future of digital finance.
