How profitable is the Antminer S9 in South Africa?       

Bitcoins have become harder and harder to mine for various reasons. With more and more bitcoins discovered, the difficult has risen from 520,569,941 GH/s to the present record high of 1,426,731,353 GH/s. This is a tripling of difficulty in mining bitcoins. This might paint a bleak picture of the profitability of bitcoin mining, but equipment like the Antminer have become more powerful.

We previously looked at how profitable Crypto currency mining can be in South Africa. Today, we’ll look at a specific piece of equipment that is very popular in Bitcoin mining circles. It’s the new Antminer S9, a 14TH bitcoin miner.

Not only does it have added processing power, it also draws around 1372W in power, which is a pretty low rate, compared to technology that existed even 10 years ago. This means that our profit can still be as high as it was previously.

Cost and Profit

One can buy an Antminer S9 for as little as 43,000 rand. However, you are more likely to find one around 55,000 rand. This might seem like a steep investment upfront, but we will show you that you are likely to break even in around an year.

With this processing rate, you will be looking at mining around Ƀ 0.001070 per day. This would be around 120.47 South African Rand per day, at current exchange rates. The power cost for this would be around 32.91 Rand per day, and could be even lower, depending on your tariff.

This would net you around 2632 Rand per month. In an year, you’re looking at a profit of 31,584, once you factor in the electricity payments you would have to make. If you get a cheap Antminer at around 43000 Rand, you’d break even in around 16 months, which is about a little more than an year.

Additional Factors

All the above is assuming that bitcoin prices stay stagnant or fall slightly. However, the reality is that Bitcoin prices have risen year on year since the beginning. What you could be looking at is a profit far greater than what we have shown here, which is assuming a worst case scenario. In reality, Bitcoins rose around 20 times its initial value in 2017, and if the same rate continues in 2018, then you will be looking at breaking even in less than even an year, and in fact, being at a profit greater than the price of the equipment you bought.

Assuming that you net around 0.39 Bitcoins in the year. This is around 44000 rand currently, and you would spend around 12,394.04 on electricity bills. However, if the value of Bitcoins doubles by the end of 2018 (A very conservative estimate when you realise it increased 20 times in 2017), then you would have made a profit of around 66000 rand in the year, which is far greater than the price of the Antminer. If it increases 20 times, like it did in 2017, you will have netted 867,000 Rand, which is more than 10 times the price of an Antminer


An Antminer is a wise investment to make in search of mining bitcoins in South Africa. If you can afford to invest, then this is an excellent choice to make.
