Bitcoin Mining in South Africa: How Does it Work And Is it Worth it?

cryptocurrency mining in South Africa

Cryptocurrency mining is open to anyone in the world but is it worth it? In this guide, you will learn how mining works and whether bitcoin mining in South Africa is still worth it in 2019. 

How Does Bitcoin Mining Work?

Bitcoin mining is the process through which new bitcoin are produced. When miners confirm bitcoin transactions, they receive a reward for this task in BTC. This process adds a new bitcoin into circulation. The confirmation process includes recording the transaction on a block for the network to validate. The current reward for adding a new block to the Bitcoin network is 12.5BTC.

However, mining bitcoin is not as easy as it sounds. Miners have to compete to solve a difficult mathematical puzzle and the first to solve it receives the reward. That means that when a miner solves a puzzle, a new block is added to the blockchain, and the transactions on this block are considered confirmed. The mathematical puzzle is known as a proof-of-work problem or hash function.

The performance of a miner is called a hash rate. That means that powerful miners have a higher hash rate than less powerful hardware. When miners contribute a high hash rate, the Bitcoin network becomes more secure.

The puzzle’s difficulty changes depending on the number of miners on the network. When the number of miners increases, the difficulty rises as well since the network has to maintain the frequency of generating a block every ten minutes on average. As a result, miners have to boost their computing power. When the number of miners on the network decreases, the difficulty becomes easier.

Miners, therefore, perform three crucial tasks: they facilitate the issuance of new bitcoin, they confirm bitcoin transactions, and they secure the network.

Miners have so far mined over 18 million BTC, which is about less than three million short of the total supply of 21 million.

Bitcoin Mining Starter Kit

Now that you have the basic knowledge of how bitcoin mining works, you might be wondering what you require to start bitcoin mining in South Africa. Here is what you need:

  • Mining hardware: since bitcoin mining has become highly competitive over the years, you need powerful hardware to mine profitably. The most powerful hardware currently in the market is an ASIC miner like the Antminer S17 whose hash rate is 73TH/s.
  • Bitcoin wallet: you will store your bitcoin rewards here. A good example of a bitcoin wallet is Trezor.
  • Mining pool: cryptocurrency mining in South Africa is likely to be more profitable if you join a mining pool with a high hash rate. BTC.com is an example of one of the top mining pools.
  • Cheap electricity: bitcoin mining consumes a lot of electricity. Therefore, you need to mine in an area with cheap electricity.
  • Mining software: some mining pools do not offer mining software. Thus, you will need to get software that is suitable for your mining rig. For instance, CG Miner.

Once you have acquired the above items, connect your miner to a power supply and your computer. Open your mining software and enter your pool’s log-in details. Now, you can start mining bitcoin.

Is it Worth It to Mine Bitcoin At Home?

bitcoin miningMining on a small scale is no longer profitable unless you have access to extremely cheap electricity. As a result, to profitably mine bitcoin at home, you will need to join a mining pool with a high hash rate. The combined hash rate of a mining pool increases the chances of solving the mathematical problem and receiving a reward.

When a pool solves the puzzle, members receive the reward amount that is equal to their contributing hash rate.

However, joining the top mining pools is difficult and some are not accepting new members. That leaves the small mining pools that are may not even be profitable. So, is it worth it to mine bitcoin at home? Probably not. But under the right conditions, it could be.

Is Bitcoin Mining in South Africa Profitable?

The profitability of bitcoin mining in South Africa depends on the following factors:

  • Electricity cost: According to global 2018 electricity costs, South Africa has electricity prices of $0.09 per kWh. On the other hand, electricity prices in Burma and Egypt are the cheapest at $0.02 per kWh according to a report by Elite Mining. By reducing your electricity costs, your bitcoin mining business has a higher likelihood of becoming profitable.
  • Hardware price: the cost of your mining hardware will play a huge role in determining whether you make a profit or loss. Powerful miners tend to be pricy.
  • Mining difficulty: the mining difficulty has been on the increase over time which means that it is hard to predict how difficult it is to mine bitcoin in the future.
  • Miner’s hash rate: a miner with a high hash rate increases your chances of solving the mathematical puzzle.
  • Mining pool fees: as a member of a mining pool, your total profits will be minus the mining pool fees. However, some pools do not charge a fee but require their members to make a subscription.
  • Bitcoin’s price: the rise and fall of bitcoin’s price affects the number of participating miners. The market upturn in mid-2019, for instance, triggered an increase in the number of bitcoin miners.
  • Power consumption: miners consume different amounts of energy. You should, therefore, calculate the profitability of using a given miner before purchasing it.
  • Bitcoin reward per block: the amount of bitcoin that miners receive per block is declining since it halves in about four years. The next halving will take place in 2020.

To make a profit with bitcoin mining in South Africa, your expenses such as the electricity cost and the hardware price should be lower than your earnings. Moreover, you should choose a mining pool that is not only profitable but also charges a low fee so that it will not negatively affect your earnings.

Nevertheless, since it is hard to predict bitcoin’s price and the mining difficulty, calculating your potential profits is more of an estimate than a guarantee. According to the profit calculator below, bitcoin mining in South Africa is unprofitable at the current market conditions if, for example, you are using one Dragonmint T16 (with a hash rate is 16TH/s) to mine.

There is no simple answer to the question: “Is bitcoin mining in South Africa worth it?” There are many factors to consider, some of which are unpredictable. Therefore, your earnings could swing in either direction. However, the rising cost of ASIC miners, the increasing mining difficulty, and the halving of the block reward in 2020 are aspects that are making bitcoin mining appear less and less lucrative.
