WITH English language the word “mining” is translated as the extraction of minerals from the bowels of the Earth. And cryptocurrency means virtual money that has no physical expression.

In simple words, mining is the “extraction” of conventional monetary units using computer technology.

The history of the emergence of cryptocurrency and mining

Currently, high-power GPU farms and ASICs can surprise only those who have not yet heard of computers and are not familiar with the keyboard and mouse. Yes, such people still exist, but there are only a few thousand of them. Today's multimillion-dollar youth are even too familiar with the terminology. In their parents' apartments and houses, they organize primitive mini-farms and scare the neighboring grandmothers with the noise of fan equipment.

The date of appearance of virtual currency mined using a computer is considered to be 01/03/2009. On that day, a block of Bitcoin with a reward of 50 coins was mined for the first time. The founder of the BTC cryptocurrency, Satoshi Nakamoto, received the first bonus. There is a version in the miner community that the Japanese mined over a million BTC before the publication of his invention.

This opinion has not been confirmed by facts. Based on the fact that from the date of the appearance of the cryptocurrency and the first publication of the client of the Bitcoin v0.1 Internet network, only 15 blocks were received, from 0 to 14, Satoshi owned only 750 bitcoins. Later he had competitors. The first exchange on the network took place on January 12, 2009. Satoshi and Hel Finney performed this procedure for the amount of 10 BTC. On that day, only five transactions were made from the cryptocurrency founder’s address, totaling 32 BTC.

Technically, receiving Bitcoin on processors is a normal operation that calculates hashes using the SHA256 algorithm. It is also performed in other processes not related to virtual money. In the first months of the development of virtual money, CPU mining was not of interest and was not very popular.

Significant changes happened almost a year later. On December 30, 2009, a change occurred that complicated Bitcoin mining. The process showed that hundreds of processors are mining BTC. And on July 16, 2010, after a publication about Bitcoin on the Slashdot website, the highest increase in difficulty occurred in one recalculation - 4 times. In just a week, the number of miners has increased many times over. AND cryptocurrency began to actively gain momentum in bitcoins, and then in new analogues.

Current state of the market

There are more and more people wanting to make money with virtual money. Many users have built entire mining farms for mining. Other market participants who do not have enough resources for mining have taken up trading. In the latter case, ensuring productive trading largely depends on the moral requirements of the trader. Understanding the dependence of the price of cryptocurrency on current conditions and future prospects. When working with virtual money, a trader needs to be able to calculate patterns and take into account the peculiarities of trading, options for a full analysis of the current situation and its development in the future, depending on current news.

Passive mining of cryptocurrencies is no less profitable option for making a profit.

IN lately The direction of providing users for rent is actively developing:

• Premises for equipment placement;
• Computer equipment ready for the immediate start of the process;
• Fully equipped mining farm;
• Capacities that allow you to mine cryptocurrency without your own equipment.

Now it is not necessary to endanger your loved ones and neighbors due to equipment fire due to overloads on the power grid. Experience inconvenience from excessive noise from constantly running devices that cool the mining rig. It is enough to rent a room in a special “hotel” and you can safely extract the selected cryptocurrency option from the “depths of the system”.

Where does mining begin?

The development of the virtual money market continues actively despite the opposition of some circumstances. The main one is the need to reconsider many areas of life in connection with the introduction of cryptocurrencies. Copy protection, text from the site zarabotat-dengi-doma.ru. Today's authorities do not want to do this and recognize virtual money at the state level. But a locomotive that is actively gaining momentum is practically unstoppable.

To date, more than 900 cryptocurrencies have already become known. And every year there are more and more of them.

List of popular cryptocurrencies

The main virtual money that are popular among miners are:

• Bitcoin.
• Litecoin.
• Ethereum.
• Monero.
• Primecoin.
• Fizercoin.

I buy Ripple cryptocurrency here - link . It also needed to be added to the list, I think the next review will be about this cryptocurrency.

1. Bitcoin is the “ancestor” and the most popular type of virtual finance. The issue of bitcoins is limited and amounts to 21,000,000 BTC. At the moment, this limit has not yet been reached. The cost of 1 BTC in US dollar equivalent is $8,500. Cryptocurrency is in high demand, exchanged on exchanges, and accepted as direct payment for goods and services. BTC is accepted in the largest online stores and online services.
2. Litecoin emerged as an alternative to Bitcoin and became its biggest rival. Segwit litecoin production technology allows you to not limit the number of transactions per second. The current rate of 1.00 LTC is equal to $88.05. Litecoin ranks sixth in terms of capitalization.
3. Ethereum occupies a leading position in the virtual money market. When mining coins, smart contracts are used. Sberbank of Russia works with this virtual currency, which makes it more convenient to use and operate on stock markets. ETH/USD rate = 1.00/482.5.
4. Monero has no maximum emission limits. It occupies the first positions on virtual finance exchanges. A significant drawback is the lack of complete user anonymity. This causes distrust among many miners. But in the mining of monero, the results are more impressive, which awakens attention to it. Current rate XMR/USD = 1.00/144.80.
5. The creation of Primecoin was similar to Bitcoin. At the same time, significant changes were made. The first feature is that the algorithm is aimed at ensuring maximum usefulness of the calculations performed. This approach increases the service life of computers. The second nuance is the unlimited emission. Mining coins is quite simple, but exchanging them for fiat money is difficult. The situation may improve, as primecoins have a good future prospects.
6. The Feathercoin coin is developed on the basis of Litecoins. Before spending it, it was necessary to exchange it for other virtual money. The emergence of an online store selling fischercoins has made it more popular. There has been a significant increase in those wishing to mine Feathercoin after the introduction of a fork with the NeoScrypt algorithm.

Over the past two years, the value and popularity of crypto coins has increased significantly. From entertainment, mining has become in a good way earn money. Expanding the possibilities for withdrawing and paying for goods and services attracts the attention of users who want to engage in mining to cryptocurrencies.

How cryptocurrencies are mined

The process consists of the user’s activities to maintain the functioning of the network by creating and closing blockchains using computing power. The owner of the hardware uses its power to perform special calculations, as a result of which he finds the digital signature (hash) that closes the block. The miner who achieves the final result receives a bonus - one unit of cryptocurrency.

In simple words, mining is the process of obtaining virtual money by exploiting the power of special equipment. At the first stages of development of the process, mining was carried out from any PC using the power of the processor. With the increase in the minimum requirements for cryptocurrency mining, it was necessary to attract more functional equipment.

Today, receiving coins even on the most productive CPUs has become unprofitable!

They were replaced by video cards and special ASIC equipment. Farms have become popular - special installations in which a large number of video cards and ASICs are connected to increase power. Today you can mine digitalnote, monero, and phasecoin cryptocurrencies on an ordinary PC. At the same time, even the most powerful computers in the world do not allow you to earn more than a few tens of cents per day.

Miner associations

As the difficulty of mining coins increases, and this increases with the arrival of new miners, the likelihood of receiving them has decreased.

Today, the average time to search for a digital signature, even on the most powerful solo equipment, for Bitcoin and Ethereum is several years. The time is theoretical, but in practice it can last for many years. This situation led to the unification of coin miners into mining pools.

United in a common “brigade”, thousands of virtual coin seekers find rewards relatively quickly. The higher the computing power of the mining pool, the higher the likelihood of receiving a bonus. In such associations, individual miners who have the simplest equipment, solve “balls” and find no blocks, still receive a reward.

The probability of a block being closed by a large pool of “prospectors” is much higher than that of a small pool receiving a coin. The reward is distributed in proportion to the connected capacities. The more work done by one miner, the higher the reward he will receive.

Types of cryptocurrency mining

Conventionally, coin mining is classified according to the form of mining and the equipment involved in the process of searching and closing a block.

Main types of cryptocurrency mining:

• CPU-mining is a practically useless method of obtaining coins. Relevant if free electricity supply, access to a large number PC.
• GPU mining is relevant for many virtual coins. An economic effect is possible when using powerful GeForce and Radeon video cards. Good option for mining coins, the cost of which may increase several times.
• ASIC mining is an effective option for searching for crypto coins. The equipment is manufactured specifically for mining. Have high efficiency. The devices quickly pay for themselves and are easy to maintain. When purchasing equipment, you need to keep in mind that it quickly becomes outdated. In this regard, its liquidity on the secondary market is low. In order to create a farm and increase capacity in the future, mining on ASICs shows good results.

Mining farms are installations that combine several powerful GPU video cards. A highly efficient way to mine coins. The equipment is in high demand among miners. The industry is not able to provide it, so the equipment is easily sold on the secondary market.

Age spots or, as they are otherwise called, solar lentiginosis, cause a lot of inconvenience to a person. They are dark areas of the skin caused by age-related or hormonal changes and ultraviolet rays of the sun. They vary in the area covered, in most cases they are not convex and are almost black in color. There are many ways to treat age spots, one of them is a Spotner pencil.

• Arms and hands;
• Neckline and chest area;
• Face;
• Shoulder area.

They are diagnosed in the older generation, usually from 40 years of age and above. It is during this period that the ability of the epidermis to independently recover from the influence of ultraviolet radiation decreases. Statistics confirm that the appearance of age spots is possible in every person, but the probability is high in light-skinned people. They do not pose any danger and do not need to be treated. The only aspect is unattractiveness. In this situation, they are trying to completely remove them or lighten them a little.
