The complexity of the bitcoins mining has fixed many strong monthly increases since its inception, and especially since the end of November 2015.


Forecast and bitcoin mining prospects for 2018

In 2017, the level of production complexity almost tripled, rising from 520,569,941GH / s to the current record high of 1,426,731,353 GH / s.

This peak was reached in late 2017. Such huge growth was caused by large investments in technology and ways to extract bitcoins.

Such growth is impressive, making Bitcoin the most powerful computer network in the world in 2018, one of the unforeseen consequences of such rapid growth was increased centralization.

BITMAIN Antminer S9

Profit accumulated where extraction is the most profitable (China), as a result of which several competing companies (for example, KNC) were forced out of the industry.

We tried to calculate the amount of money that the Chinese invested in mining, we estimate it in hundreds of millions of dollars.

Even with free electricity, we can not know for sure when a farm set up manually  or ready-made miner  work out the invested money.

Either they do not know what they are doing, but this is unlikely on such a scale, or they have some secret advantage that we do not know about. – Sam Cole, CEO of KNC.

At this stage, most home or office miners do not hash to earn money, but rather support the network and decentralize assistance.

Bitmain Antminer S9 Overview

With a decline in the level of profitability in the block, the profitability of all but the most efficient operations is likely to be called into question. Considering that the profit received from the current generation of equipment for mining is being reduced and is likely to reach a negative profitability when expenses exceed revenues.

Setting up Antminer S9

Before buying the Antminer S9, make sure that you already have bitmaker software and a bitlock pool. The first batch of S9 was available for order directly from Bitmain from June 12, 2017.

S9 is far from cheap, the price is $ 2100 on Amazon. However, the lower the cost of electricity, the better your chances are that it will quickly pay for itself. Naturally, a lot depends on the complexity and course bitcoin.

Since smaller production farms are becoming standard for this industry, and other manufacturers are releasing competing mining devices, it is expected that the S9 price will drop significantly in the coming months.

Bi Wang launches its 14-nm chips and is reportedly soon to release its own architectural hardware BitFury, which has a 16-nm architecture, promising fantastic energy efficiency at 0.06 J / GHz.

In the near future, most likely, there will be nothing technologically superior to Bitmain Antminer S9. From now on, the cycle of release of a new generation of equipment for mining every few months can slow down, as manufacturers switched to advanced development of 16 and 14 nm.

AntMiner APW-12

AntMiner APW-12 1600W bitcoin Miner PSU, which sells for $ 200 on Amazon, and a power supply GPU EVGA SuperNOVA 1300W, which sells about 170 US dollars on Amazon.

Please note that the 1600 Watt EVGA PSU is significantly more expensive, about $ 115, than the proposal offered by Ant Miner with equivalent power.

Bitcoins / Month (Profitability). S9 has more hashing power than any previous device clogged in its silicon; massive 14 TH / s (TeraHash per second).

A total of 189 chips distributed over 3 cards are combined to achieve this phenomenal hash.

Including 15 short-term TH / S surges that occurred at the end of 2011, there may be one single S9 hash hat, equivalent to the maximum throughput of the entire Bitcoin network from its initial download to mid-2012.

Antminer S9 payback and rate of return in 2018

Let’s calculate the projected profit from all this hash power: notice that the cost of power will be specific for your location and that the level of complexity changes every 2 weeks, usually up …

Although keep in mind that after half-realization it is quite possible that many marginal miners will be forced either to modernize, or improve equipment, or to close.

Although S9 is quite powerful equipment, a single unit is unlikely to find any blocks in solo mining. Finally, the price of bitcoin for US dollars is known for its constant flow state.

According to the latest data, AntMiner S9 will produce 0.285 BTC (bitcoin) per month and 3.36 BTC (Bitcoin) per year. These conditions will pay back its cost for one year!

Of course, such impressive results suggest that all factors and the course of bitcoins will remain the same, which is extremely unlikely in the rapidly changing world of bitcoins!

The most advanced manufacturing process is what makes the S9 the most electrically effective mining device to date.

It uses only 0.1 J of gigashash, which makes it about 2.5 times more efficient than the Antminer S7. The total power consumption of the device is about 1350 watts, although this figure accounts for about 7% of the variance.

S9 consumes 300 watts more than S7. SetupApart from the power source, S9 – autonomous unit. It does not require a connection to another computer to interact with other bitcoins. Its web management makes it easy to configure and maintain.

What is Antminer S9 advantage?

The continuing miniaturization of semiconductors provides increasingly computational power and electrical efficiency, but this process can not continue forever using the existing technology.

Many noted that Moore’s law is no longer valid, since the speed of progress in data transmission has slowed as it reaches physical limitations of semiconductor technology.

The manufacturing process of 16 nm, used in the manufacture of S9, is the main improvement in the design of 28 nm, characteristic of other modern mining devices.

Although the 10-nm process is on the horizon for 2018, further increase in power and speed goes beyond the theoretical framework. In addition, the design and manufacture of any 10-nm technology equipment Bitcoin is likely to take at least a year.

Comparing Antminer S9 mining speed with other devices

Antminer S9 issues 14.0 TH / s, now its average cost is 3000 $, when

  • Antminer S5 will give 1.16 TH / s at an average cost of $ 139.99
  • The Antminer S7’s speed is 4.73 TH / s with an average price of $ 489.99 on the market
  • Miner Avalon 6 issues 3.50 TH / s for the unit you need to pay $ 559.95
  • Miner SP20 Jackson issues 1.3-1.7 TH / s for this it costs a little $ 90.00
  • The Antminer R4 hash speed is 8.6 TH / s, be prepared to pay $ 1000 for the hardware

Thus, the high cost of Antminer S9 is due to the advantage over other devices and profitability in the mining of crypto currency.

Antminer S9 power consumption

The good news is that existing power supplies are at least of sufficient power and are fully compatible with S9.

Antminer S9 heating temperature

The S9 is air-cooled, and its sturdy construction is fairly simple to maintain. S9 works reliably in any well-ventilated room, whether it is one or more pieces working in a room or in a large farm.

Reviews about Antminer S9

Does mining bitkonov with Antminer S9 benefit? Based on the results computed above – yes, it makes sense. But! as major miners move to S9 and other advanced hardware, the resulting complexity of mining can reduce future profitability.

On the other hand, a halving can lead to a higher price of bitcoins and a decrease in competition, which will lead to higher profitability and profitability.

Ultimately, the S9 is an excellent device for mining, although at present it is quite expensive. It is likely to remain profitable much longer than previous generations of ASIC, although ROI can not be guaranteed given the inherent unpredictability of Bitcoin mining.
