Model Antminer R4 from Bitmain mining SHA-256 algorithm with a maximum hashrate of 8.7Th/s for a power consumption of 845W.

Overview

The Antminer R4 was produced in the year February 2017. It runs at a specified hash rate of 8.6Th/s and power consumption of 845W +9. Unlike other versions of the Antminer, the Antminer R4 has a great design that sets it apart. The R4 happens to be one of the most efficient miners produced into the market, with about 0.1J/GH's power efficiency.

Setup

The Setup is simple, you find the IP, the DHCP is enabled, and once it is enabled, type root for both the username and password. Once you’ve gained access, the menus are enabled for easy setup and operation. When the miner is switched on, it produces an immense amount of noise that is hazardous in any residential area. This can be avoided by placing a cap on the sound generated by the machine.

Price

The Antminer doesn't exactly come off cheap, priced at slightly higher than $1000, and it is described as more expensive than other devices out there. This high cost puts the machine out of reach for hobbyist miners.

Profitability

The profitability of any Miner is due to its hash rate, and because the R4 is the second most profitable miner after the S9, having a high hash rate means that it will have higher profitability.

Most miners' major aim is to make a profit, and the R4 consumes 845Watts with an APW5 PSU Power supply. It will take you about 527days to earn back your investments, assuming your total investment is $1000 for the miner and about $240 for the power supply, provided the energy bills remain under the $0.10 per kWh.

Algorithm of the Bitmain Antminer R4

Bitmain is a leading Bitcoin mining equipment manufacturer. The unit in question is using the SHA-256 algorithm. Most pundits hail this hashing algorithm for the safety it offers. It’s one of the best in terms of security and speed. Users get the protection they need from the 51 percent attack. And this is why dealing with such a miner almost guarantees profitability for miners.

Efficiency of the Antminer R4

There’s an efficiency of 0.097j/Gh that comes with this unit. The efficiency is as a result of the hash rate and power consumption. Most will claim that the efficiency is lower than other Bitcoin miners, which is true. The lower efficiency is as a result of low power consumption. The miner comes with a power consumption of 845W. These are the two reasons why the miner has lower efficiency.

The advantage of having low power is lowering the electricity cost. Those who use this miner will incur lower electricity costs. The miner will mine longer than other units as a result of low power. These are the features you need to consider when buying a Bitcoin miner. The R4 is best for newbies and those who prefer mining at home.

The Profitability of Bitmain Antminer R4

Due to the current market conditions, the unit has a negative profit ratio. The profit ratio for this miner is -21 percent, with an annual return percentage of -19 percent. It comes with an estimated power cost of $2 daily. The power cost is affected by the electricity rates in your area. Those with lower electricity rates will get a profitable outcome. The manufacturer does not issue a payback period for this miner.

Warranty of the R4 Antminer

It comes with six months of warranty that covers the initial buyer. Users should take note that this particular model is completely sold out.
