Market Cap

Ethereum currently uses mining to add new coins to its circulating supply. The participants, known as miners, use the Proof of Work (PoW) mechanism to create a new block by solving complex mathematical equations, although in the coming years, there is a plan for Ethereum 2.0 to transition to Proof of Stake (PoS). The first miner to solve any puzzle gets rewarded for creating the new block.

Other participants verify the block before it's added to the blockchain. So, without miners, no one can create new coins on the network. You can mine Ethereum either on your own or through a mining pool. In this tutorial, you’ll learn the best way to mine Ethereum profitably.

Breaking Down Ethereum Mining

This section explores what Ethereum mining details. It offers tips that miners need to mine the coin profitably. We aim to give you all the essential information you need on this subject, including miners’ role in securing the Ethereum network and creating new blocks.

What is Ethereum Mining?

The Ethereum network allows miners to add new blocks after an average of around 15 seconds. As a reward, they receive 2 ETH plus gas. They can also get a bonus for updating the ledger and securing the network.

After successfully solving a mathematical problem, a miner broadcasts this new development to other network participants. If 51% or more of the participants agree that the answer is correct, the new block is added to the blockchain. Miners then start solving a new problem, and the process continues.

Due to decentralization, the Ethereum network gives participants much power to control the production of new coins. Nonetheless, the PoW mechanism reduces the risk of mismanagement. More than half of miners must validate all Ethereum transactions. This means millions of participants are required to make crucial decisions.

Why Ethereum Miners are Important

In the previous part, we have presented how the Ethereum mining process works. One thing stands out: miners validate transactions and secure the network. In particular, they prevent the double-spending problem.

In decentralized systems, some individuals can take advantage of a few loopholes in the network to duplicate transactions. This threat was responsible for the delayed adoption of cryptocurrency.

Blockchain technology ensures that all blocks are timestamped and assigned a unique hash (special number). Each of them also contains a timestamp of the previous block, eliminating the risk of changing when a transaction took place.

The hashrate boosts the reliability of the Ethereum network. When the number of miners on the network increases, its hashrate rises. It also increases the network’s security given that more participants are required to verify transactions and make critical security and managerial decisions.

The Ethereum network, therefore, depends on miners to be safe and continue building its blockchain. Miners, therefore, should get block rewards, bonuses, and more for their service.

Ethereum Mining Limitations

ETH is one of the few cryptos with a fixed issuance schedule. It issues two new coins into circulation for every block introduced on the network. 

The number of active participants, transactions, or the market price has no impact on the supply.

If the supply outpaces the demand, ETH could become an inflationary currency. However, the current limited issuance schedule of 2 ETH/block may minimize the risk.

In 2019, the fixed issuance schedule was 3 ETH/block. Two years earlier, it was 5 ETH/block. This means the issuance supply is steadily decreasing.

ETH doesn’t have a limited number of coins like Bitcoin. However, the supply is capped at 18 million ETH per year. So, it mimics fiat currency. However, since the annual limit doesn’t reflect the changing economic factors globally, the crypto could be exposed to inflation. It potentially has a fee-burning mechanism that takes away some coins from circulation to prevent this, and this could be implemented in July 2021.

Ethereum intends to transition to Proof of Stake (PoS), which is more cost-effective and energy-efficient than PoW. 

This move is expected to reduce the issuance rate from about 5% to less than 1% per year from 2022. With no increase in the total supply under this new model, the price of ETH could increase as the mining difficulty goes up.

Tip to Mine Ethereum Efficiently for Greater Profits

If you want to mine Ethereum efficiently for greater profits in 2021, you can invest in mining hardware and join one of the best mining pools. Alternatively, you can purchase a credible and affordable cloud mining service. If you choose to join an Ethereum mining pool, ensure it uses cheap electricity. For the latter, consider whether the reward share and the terms and conditions of the contract are acceptable. Standalone Ethereum mining no longer works due to increased mining difficulty. Mining pools and cloud mining services with highly efficient machines and sources required to cushion you from huge losses are the only viable options.

Technical Aspects of Mining Ethereum Explained

In this section, we cover some of the technical aspects of mining Ethereum. We’ve selected those that you need to mine the coin profitably, like hashrate and processing power. This section explains the benefits of a higher hashrate within the Ethereum network and more.

Hashrate Simplified for Cryptocurrency

  • What does hashrate mean?

In simple terms, hashrate is the number of attempts an Ethereum miner can make to create a new block within a given time. It can also be defined as the speed of mining. Hashrate determines the computing power of miners.

When the number of participants within the Ethereum network increases, the hashrate for the entire system also increases. However, as this happens, the proportional hashrate for individual miners drops.

  • Why is a higher hashrate important?

As we have seen above, a higher hashrate for the network means two different things to the network and the participants. It means an increase in competition to miners. So, they can make limited successful guesses.

At the same time, it means the network is more secure. If a bad actor intends to attack the Ethereum network when the hashrate is high, they are likely to fail. It costs too much to control at least half of the miners at such times. In other words, a higher hashrate provides the best protection against 51% attacks and the ensuing problems. Moreover, it ensures speedy validation of transactions.

  • How is hashrate measured?

Hashrate is measured in solutions (or hash) per second (h/s). It uses other prefixes like K (kilo), M (mega), G (giga), or T (tera), to denote orders of magnitude.

  • 1Kh/s means 1 000h/s
  • 1 Mh/s means 1 000 Kh/s or 1 000 000 h/s
  • 1 Gh/s means 1 000 MH/s, 1 000 0000 Kh/s, or 1 000 000 000 h/s
  • 1 Th/s means 1 000 Gh/s, 1 000 000 Mh/s, or 1,000 0000 000 Kh/s, or 1 000 000 000 000 h/s

The Ethereum hashrate currently stands at 482.703 TH/s. This figure has been calculated using the current average Ethereum network difficulty above 6,000 Th as of March 28, 2021.

Processing Power: CPU & GPU

Due to the high network difficulty, network participants no longer use central processing units (CPUs) to mine Ethereum. Their efficiency is about 5 Mh/s. The use of graphics processing units (GPUs) is on the rise since they can produce at least 68 Mh/s. GPUs can be used for many different hashing algorithms, as they are not specifically built for just one.

The Ethash PoW algorithm that the cryptocurrency uses is fairly ASIC-resistant. So, few miners have adopted application-specific integrated circuits (ASICs) despite their incredibly high processing power of up to 110 TH/s. Remember, these machines are custom-built, and can only be used for one hashing algorithm.

The emergence of Field-programmable Gate Arrays (FPGAs) signaled a major change in the mining of Ethereum. These are capable of 800 Mh/s, highly adaptable like GPUs, and affordable. However, the requirement to build the software and the digital circuit design has hindered its widespread adoption.

Hashrate needed to mine Ethereum profitably

As you can see below, mining Ethereum is harder today than ever before. The network difficulty has gone past the 6,000 Th mark for the first time, and the diagram suggests that it has been increasing steadily since July 2015.

So, how much would it cost to mine one Ethereum today? Due to the increasing mining difficulty, you require a machine with about 15,500 Mh/s. 

Some rigs with lower efficiency may also be profitable but for a short while.

To build a mining rig with the required efficiency, you need over 50 GPUs. If possible, you can alternatively use ASICs that are compatible with Ethereum since they are twice as efficient.

DIY Ethereum Mining-How to Get Started

We provide a DIY guide to mining Ethereum in this section. We give you clear information on how to find the best mining hardware and manage your overhead costs. Besides, we help you to choose a suitable software and mining pool.

Best Mining hardware for Ethereum

GPUs remain the most efficient and reliable hardware for mining Ethereum. The network rejects most ASICs as many of them are designed to prevent smaller users from mining ETH.

Nvidia and AMD offer the best GPUs for mining Ethereum. You can use an online Ethereum profitability calculator to know how much you can earn with each of them.

Nvidia GTX 1070 Founders Edition remains one of the best GPU options. It consumes only 150 watts of power but can mine at between 27 MH/s and 31 MH/s. However, its price has increased to over $700 due to surging demand. You can find it on eBay or Amazon. If stock runs out, contact the manufacturer.

AMD RX 480 is also a popular GPU for mining Ethereum. Though this hardware is a generation behind AMD’s current product line, it’s better than the new version, RX 580, for ETH. The new hardware’s inflated price, poor cooling efficiency, and slightly higher power consumption make it less suitable for mining.  

You can opt for the ASUS RX 580 8 GB Dual-Fan OC Edition. It provides double airflow and three-times quieter mining, and mines at approximately 29 MH/s. So, it’s a great alternative considering that the RX 480 is often difficult to find in the market.

Most miners buy the AMD RX 480 from gamers who no longer use it or are willing to sell them. This GPU miner works at 24.5 MH/s without overclocking. When overclocked, it achieves up to 28 MH/s. It consumes only 150 watts and costs about $600 on Amazon.

Other Costs to be Considered

It’s important to consider power consumption. It could deplete your profits if left unchecked. 

The exact cost depends on your hardware. For example, Nvidia GTX 1070 Founders Editions consume only 150 watts and mines between 27 MH/s and 31 MH/. Nvidia Titan V consumes 188 Watts and mines at between 70 and 82 MH/s.

Besides, the cost of electricity depends on the miner’s location. For example, the price is lower in China than in some parts of the world. Mining with household electricity supplies is often unprofitable in countries like the UK.

With the current mining difficulty and the GPU trends, you could take up to six months or more to mine a single Ethereum coin.

To build a mining rig with a hashrate of 15,500 Mh/s, you require about $100,000, depending on your location. This accounts for the cost of about 50 GPUs and electricity.

Start Mining!

Other than suitable mining hardware and software, it would help if you had an Ethereum wallet to start mining. Like physical wallets, you use them to store your coins. The software gives your hardware access to the Ethereum network and the mining pool.

If you choose to join an Ethereum mining pool, you can consider Ethpool/Ethermine. These two sites contribute to a single pool and are one of the largest on the network. 

Over 125,000 miners are on Ethermine. Close to 1,100 are on the other sister website.

Nanopool is another leading Ethereum mining pool. It has over 80,000 miners. Dwarfpool is much smaller but charges a 1% fee on rewards.

Note that you should decide based on the pool size, minimum payout, electricity costs, and pool fees. Larger pools combine more hardware than smaller ones.

Before joining any mining pool, choose the right software. If you are a Microsoft Windows user, ETHminer, is ideal. It offers the option to earn per day or minute.

Claymore is another excellent Ethereum mining software. Currently, it supports dual mining. It’s also well-optimized and provides constant updates.

CCMiner is built using the C++ programming language. So, it’s compatible with most mining rigs. If you are a Mac user, Minergate is ideal. It also allows you to join an ASIC pool.

Mining Solutions/Services

If you lacked the knowledge and skills required to mine Ethereum via mining pools, we’ve provided lots of information to help  you. Mining pools are great since they combine many miners’ hardware, giving members an advantage over individual miners on the network. As we have seen, before joining any Ethereum mining pool, you must buy the necessary hardware and install the software. For some, this is tedious. So, they need an alternative.

There are several motivations for seeking an alternative mining method. Whichever reason you have, you can join a cloud mining service. It involves paying an expert miner to handle all the mining tasks on your behalf. In other words, you rent other people’s mining time, and they share with you the rewards.

This mining method relieves you from responsibility if any equipment is broken. Once you pay for the service, you have a right to ask for the agreed results. You need to be careful, though. Some companies can try to mislead you into believing their concealed lies. They make appealing verbal commitments but ask you to sign contracts that put the responsibility of ensuring the equipment works as required on you.

Cloud mining can also be a better alternative if you don’t want to keep noisy equipment in your warehouse or home.

There are several cloud mining providers in the market, but the most popular for Ethereum mining are Genesis Mining and HashFlare.

All pro miners likely know a lot about Genesis. This service provider is widely regarded as the most reputable. Many analysts have given it a thumbs up as the best developed in the cryptocurrency mining world. You get access to state of the art mining rigs and can choose from four mining plans to mine Ethereum as well as several other altcoins. One of the plans even allows you to customize the rates in a way that suits you best.

HashFlare is the most popular alternative cloud mining service for miners across the globe. Although HashFlare is largely dedicated to Bitcoin mining, it still allows those seeking to mine other coins on the cloud to access hashing power. You can therefore securely mine Ethereum and a host of other cryptocurrencies on this platform. The company offers detailed statistical data on its website and requires no maintenance fees. Besides this, they use standard GPU mining rigs.

If you need a recommendation on the best cloud mining service to join, you now have it. Since “best” is a relative term, we have given you more than four suggestions. So, you can choose the one that is best for you.

As already mentioned, you should pay careful attention to the terms and conditions in the contract before pending your signature or sending your money to any cloud mining service. If you deem fit, you can explore other cloud mining companies or the other ways of mining Ethereum. Also, consider transaction fees, electricity prices, and how to receive rewards.
