With all the awesome features that come with the Antminer R4 you would expect its price to be high.bitcoin credit card redditOne Antminer R4 costs $1,000.ethereum holdIts price is among its cons because this may be too high for the average hobby miner.Once you setup your Antminer R4 you will see that its user interface has been well designed with the users in mind.It’s very easy to use.All you have to do is enter your wallet address and mining pool settings before you start mining.ethereum portfolioIt is also possible for you to customize settings such as the fan speed or the frequency.Most of the hobby miners reading this article actually want to make money from hashing.With that in mind let’s have an in-depth look at the profitability of Antminer R4:With a hash rate of 8.6 TH/s, the Antminer R4 is the second most powerful miner, second to the Antminer S9.It has a power consumption of approximately 845 Watts at the wall using an APW5 PSU power supply.Rest easy because most homes have an outlet that can handle 845 Watts safely but also expect your electricity bills to rise significantly.Consider an investment of about $1,000 for the Antminer R4 and about $240 for the APW5 PSU.The mining profit calculator reports at the then current price of $574 Bitcoin price, it would take you approximately 527 days to return your investment provided your power cost doesn’t exceed $0.10 per KwH.Of course we assume that all factors remain constant which is almost impossible in the ever-changing world of Bitcoin.This means that the Antminer R4 will eventually produce a profit, but only if the network hash rate, Bitcoin price, and electricity costs stay the same.
