Mining in the media is covered exclusively from the point of view of extraction of crypto-currency and from this one-sided information a distorted public opinion is formed. Probably, for many, it will be a surprise to learn that the receipt of a cryptocurrency by miners is only a consequence of the work they do, but a significant result of their activities is quite different. Just as doctors or truck drivers receive a salary for their work, the miners receive remuneration for performing certain duties that are in demand by society. The emergence of the technology of decentralized databases, which revolutionized the civilization's possibilities for the remote exchange of values - money and rights, brought to life a new profession, whose representatives create and maintain the infrastructure necessary for the functioning of the detachments. In the field of mining today, everything happens in a similar way to the development of events in the period of the Internet, the emergence of which, at one time, was the first experience of contact with decentralization on a planetary scale. The basis of the infrastructure of the Internet is the server, which stores all the information that we address when connecting to the network from their computers, smartphones, and tablets. The Internet node can be any computer, but the requirements of reliability, security, and bandwidth have gradually led to the fact that the nodes of the Internet are specialized devices assembled in specialized data centers, serviced by specialized organizations. The first steps of blocking technology, as well as the Internet, was based on the power of home computers and enthusiast laptops. This was enough for experiments, support of rare transactions between a few users, but it is clearly not enough for mass implementation of blocking technologies, which gradually becomes a trend in the development of the IT industry. Today, probably, no one has any doubts that absolutely all business processes connected with the transfer of money and rights to material and intellectual assets over the network will eventually be transferred to the blockbuster. The technology is closely watched by banks, states, and transnational corporations. The number of blockers will grow, and with it the need for their support - mining will grow. The process has already begun, but the driver of growth so far is the crypto-currency market. Today's mining capacities are almost entirely used to service transactions of infrastructural objects of cryptology. Large corporations and states with their own requirements for maintaining registers are able to increase the number of transactions in blockhouses by tens and hundreds of thousands of times. Happening this momentarily today or tomorrow, the overload of existing block-network networks would be inevitable. Risks of overloading of the network networks were clearly demonstrated by the game CrytoKitties, whose viral popularity overloaded the Ethereum network and contributed to the growth of the price of gas that determines the cost of transactions. It is now impossible to reliably predict at what pace blockages will be multiplying and on what type of consensus they will work, but the very fact of increasing demand for mining services is unquestionable. As well as the birth of new forks, which the miners need not less than the parent detachments. Mining data centers are literally the environment for the existence of distributed databases, and the commission, embedded in the reward algorithm for supporting the block, makes the mining business one of the most profitable and reliable areas for investment. Advantages of investment in mining If you compare mining with a very similar in form business information datacenters, then the following distinguishing features of mining are striking: constant full capacity utilization; limitless business scaling opportunities; Payment is guaranteed by algorithms of supported blockers. In other formulations, more traditional for the business environment, all the same, can sound like this: no need to look for orders, the sales department is not required; the sales market is global and its growth is accelerating; to beat out accounts receivable there is no need, the payment arrives automatically on a course of the performance of work. Entrepreneurial instinct faced with such characteristics of mining as a business makes it necessary to look for a dirty trick. Risks of mining as a business Like in any other business, earning income in mining is connected with risks. The risks of mining are quite specific and closely intertwined with the dynamics of the development of the crypto-currency market. The income from mining in the growing market is higher, on the falling, respectively, lower. The growth of the rate of the Crypto-currency is rapidly attracting new investments into mining, which are realized in new computing capacities and competition is growing, having a direct negative impact on the income of the miner. The increasing complexity of computing and the aging of equipment reduces the share of participation of the miner in the process of forming new blocks, and, accordingly, in the generation of new coins. The high dynamics of the crypto-currency market requires the miner to react quickly to changes in the parameters of supported lock-ups-the redistribution of data center capacities between crypto-currencies, the addition of new profitable ones, and the elimination of crypto-currencies falling out of profitability. Since the whole process of mining is based on a highly loaded operation of electronic equipment, periodic failure or overheating ensures the downtime of equipment, and the financial result of the activity also depends on how quickly the personnel of the miner reacts to problems with the equipment. In itself, the presence of risks is not a critical factor in making a decision on investing in mining. Essential is the ability of the miner to manage these risks - an organization of round-the-clock technical support, selection of the type of equipment that allows switching between blockers, continuous monitoring, and forecasting of the market by the analytical service and other measures and tools that optimize work. Probably, from all above listed already it is possible to draw conclusions about tendencies in mining, as a business: 1. Increase in the value of economies of scale, contributing to the enlargement of the data mining centers; 2. Development of joint-stock forms of financing for mining; 3. The formation of specialized organizations to service the mining data centers and companies involved in mining development. Glossary Miners - people and organizations that support blockades; Mining Development - the creation of mining data centers; Investing in mining - financing the creation of mining data centers, with the receipt of income in the form of compensation for the support of the detachments.
