I will reveal to you a terrible secret – any such sold devices are unprofitable
When a long time ago, four years ago, the first ashik, created by Avalon for bitcoin mining, by a fluke (their producers were simply Not experienced and / or wrong with the calculations) brought fabulous, tenfold profits to their customers, and then it's about the very first batch of September 2012, but all the subsequent ones were already either unprofitable or on the verge. The next manufacturer, which allowed its customers to make a profit (about + 30% for half a year, and the cost itself was repulsed in the first months, and afterwards there were real pennies that should not be paid attention) – it was bitfury.
AND These were the only cases when buyers of these devices received income from mining! At best, it was possible to repel their investments and even go into a small plus, selling this device as quickly as possible at an inflated price, but it was clearly not possible for everyone.
And how do the producers deceive us?
This is very simple, especially when it comes to the only equipment manufacturers for a particular crypto currency, or one whose production capacity is a significant part of the power of the entire network. The manufacturer knows how many devices and when it will produce and when they will be launched. It's not difficult, if you make these plans yourself, and the buyers give you money in advance in 3-5 months, hoping to get into the very first batch first. Then, using simple school mathematics, calculates how many and for how long all these released devices will generate crypto currency.
A small educational program – at the moment, absolutely all crypto-currencies, bitcoin and altcoyins, are produced approximately according to the following rule: the number of coins produced is approximately constant, Moreover, almost all the production rate decreases, in order to obtain a fixed emission of coins by the end of a certain period. In bitcoin, for example, about once every 4 years, the number of coins mined sharply decreases twofold. To achieve this, the complexity of the problem solved by all the miners is automatically adjusted, and as the aggregate power of the miners increases, the complexity immediately increases. Thus, if an abstract 1000 boxes are mined in a network and 1000 coins are mined per day, giving each one one, then if you produce 1000 more, the quantity of each produced will be 0.5 coins. This process is not spasmodic, smeared in time, where there is more growth, where it is less, it will not work, it depends on the work of customs and delivery services, plus the manufacturers themselves do not immediately give out the devices.
So, the manufacturer Knows exactly how much the box produced by him at best will generate coins, and puts the value in his store exactly so much or even more
… taking into account the cost of electricity, the risks of breakage and maintenance costs. I remind you – the calculation goes in the crypto currency that this device produces. Of course, in the store you will withdraw the amount in a fiat currency, for example, dollars. In fact, manufacturers are much smarter, the experience is already good. Since the producers are usually rich enough, additional manipulations with the rate of this particular currency are possible at the time of placing lots for sale, it is necessary to hold the high cost, or rather the growth, a few days, a maximum of a week. Or just wait for such growth, when any large stock exchange or market maker it propampyat. It is also known that practically all significant altcoyins grow in one way or another with the growth of the main bitcoin, and fall with its fall, not immediately but on average, in the assessment for several months.
Everything depends on how the buyer behaves . Usually, when he sees the price of a device for mining, he goes to Google and searches for the first bitcoin profit | mining calculator, drives in the parameters of the device and receives a nice sign-income for the day, for the week, month, and year. He sees beautiful numbers, the device fights for three months, and then brings a lot more, and with screams of joy runs and pays money. Slightly more clever, click on several links, find the calculator smarter, taking into account the growth rate and complexity, and there too, are beautiful numbers, maybe a little less but also green, with an investment return of 6 months. Even more intelligent, read reviews of previous customers, how they overcame difficulties and struggling with noise and dust and a broken cooling system, received an income after the first 9 months – in rubles / dollars, and then they immediately give up the product for the purchase of another device. Of course, in the head of such grief of investors turns – and where you saw that the incomes were at once – it is necessary to work, and still bear and carry money.
Cases when the first buyers receive a small income, on the verge of errors in calculations Evaluation of producers. This happens when there are several manufacturers and they were not able to agree with each other normally (the first companies were rumored to agree on the amount of output capacity, but then, as it is logical, someone threw the whole gop company, and now there is pure anarchy), and Then, if the estimation error was in the smaller side. This is normal – the manufacturer is simply simpler instead of wasting time and effort to organize, build and maintain gigawatt datacenters to host their devices, just sell them, even slightly with a smaller income, but this is not a problem, then you can still release the next batch. More precisely, the equipment manufacturers for mining are the same miners, they come to this market with plans to mine independently, and some even hold a certain percentage of their capacities, because this is support for their investments, literal – the miners determine the future of the crypto currency, decide on Whether to make changes to the protocol and standards or not. It's just that the mind wins – the risks need to be diversified and transferred to others.
The crypto currency production device is never idle
And it's logical, it would be foolish to keep just in the warehouse these truly magical devices. Therefore, the producers of the mines before sending the customers, the first of them fired the terms of mining, indicating in the default settings the parameters of their accounts on pools where the statistics of the work are public. Sometimes these terms were so large that they showed how the manufacturer received an income exceeding the cost of the device already sold by him, simply delaying sending for a week or more. Be reasonable, now manufacturers do the same, just hide their activities better.
Why is it important to consider the value in the crypto currency or even bitcoin and not in dollars
Because there is another simple way to earn income in the fiat currencies – speculative trading, with the purchase and preservation of the crypto currency, and more often it is bitcoin for a long time – a year or more. If you want to earn income from activities in crypto-economics, you should compare them with this method. And since until now, bitcoin is continuously growing, it makes sense. Therefore, if you are thinking of earning a profit by growing the rate, just buy this crypto currency and wait for the growth of its value.
What other risks and costs, if all the same, engage in mining
Firstly, it is the time delays in obtaining the device. In addition to unscrupulous manufacturers holding the device at home, there is also a delivery service and customs. They create the main problems for domestic miners. The latter can not miss the device at all, pointing to the lack of notification – almost all devices do not have it, and it does not matter, when even there was a producer who wasted time and potential income of miners for receiving it for Russian customs,
Secondly, the costs, in addition to electricity, also require cooling of the premises – and this, or rather expensive air conditioners, or systems for the removal of hot air, and hence the supply of cold from the street, with filtration from dust and insects. Also, this is the cost of the room itself, because at home, next to the bed, very noisy and even dangerous to the body of the box can not hold (very harmful dust that coolers cool down, it is passed into the lungs of the nose, due to the fact that it Very small, when you have one computer – it's not scary when you have a dozen and you breathe this constantly …).
Third, it's the cost of maintenance. Cooler coolers, depending on the temperature regime, fail and require replacement – this is considered an expense. Also, power supplies are broken, not often enough to pay attention to this in the calculations. The boards themselves break down, which can also require a reaction from the owner, sometimes this is the disconnection of the failed card, sometimes fixing it by replacing the burned element – this requires at least a specialist whose time and knowledge are not free.
Fourthly, you You can not take into account the problems associated with the crypto currency itself. For example, during the year you receive small payments to your wallet, and then when the amount in dollars becomes sufficient to assume that you are on income, you are going to transfer the entire amount to the exchanger and get, suddenly, a commission comparable or more than all your money on the account . You frantically start to study the question, and it turns out that you have a lot of dust and your transaction is too much in bytes, and now bitcoin has big organizational problems and transactions are very expensive.
Why are there people who claim that Receive income?
Because they believe in fiat currencies, and the rate just jumped.
Because they are "stealing" electricity and do not pay rent of a room in which they keep their own ashks.
Because they trade the extracted crypto currency, judging by everything successfully, if they have an income.
Because they want to sell you this device and really end up earning income at your expense.
