Wichtige Erkenntnisse

Das Mining von Kryptowährungen ist ein wichtiger Teil des Prozesses zur Ordnung und Validierung von Blockchain-Transaktionen. Mining ist auch dafür verantwortlich, neue Einheiten von Kryptowährungen zu erstellen.

Während die Arbeit der Miner intensive Rechenressourcen erfordert, hilft sie dabei, ein Blockchain-Netzwerk sicher zu halten.

Miner sammeln ausstehende Transaktionen und organisieren sie in Blöcken, die dann an das Netzwerk gesendet werden. Wenn der Block von den validierenden Knoten genehmigt wird, erhält der Miner die Blockbelohnung.

Key Takeaways

Cryptocurrency mining uses computational power to validate transactions and add new blocks to a Proof of Work blockchain, with miners receiving block rewards in return.

The main mining hardware types are ASIC miners (purpose-built and efficient), GPU rigs (more flexible but lower returns on most coins), and CPUs (viable only for a small number of coins).

Joining a mining pool increases the frequency of earning smaller, more predictable rewards compared to solo mining, where the odds of winning a full block reward are extremely low.

Electricity cost is the single most important variable in mining profitability. Use a profitability calculator before committing to any hardware.

Cryptocurrency mining is the process by which new transactions are verified and added to a blockchain. Miners contribute computational power to solve cryptographic puzzles, and the first to find a valid solution earns a block reward. For a detailed explanation of the underlying mechanics, see What Is Crypto Mining and How Does It Work. This guide focuses on the practical steps: choosing a coin, selecting hardware, setting up software, and evaluating whether mining makes sense for your situation.

While anyone can start mining, the economics vary widely depending on hardware, electricity costs, mining difficulty, and the market value of the coin being mined. This article covers what you need to know before getting started.

What Is Cryptocurrency Mining?

Bitcoin, Litecoin, Dogecoin, Ethereum Classic, and many other networks use the Proof of Work (PoW) consensus algorithm. Under PoW, miners compete to solve complex mathematical puzzles. The winner adds the next block of transactions to the chain and receives a block reward plus any transaction fees included in that block.

The hash rate of a miner refers to the number of calculations it can perform per second. A higher hash rate increases the probability of solving the puzzle first, but the overall network difficulty adjusts regularly to keep average block times consistent regardless of how much total computing power is participating. As more miners join, difficulty rises; as miners leave, it falls.

Bitcoin's block reward is subject to periodic halvings. The most recent halving in April 2024 reduced the reward from 6.25 BTC to 3.125 BTC per block. This event directly affects mining revenue, making profitability calculations made before April 2024 unreliable as a reference.

Types of Mining Hardware

Your choice of hardware determines which coins you can mine, your electricity consumption, and your potential returns. Before purchasing any equipment, see our guide to crypto mining rigs for a more detailed breakdown.

ASIC miners

Application-specific integrated circuits (ASICs) are designed exclusively for mining a specific hashing algorithm. They offer the highest efficiency for supported coins, which makes them the standard hardware for Bitcoin mining. Current-generation ASICs can deliver better energy efficiency than older models, though their upfront cost is substantial.

A key consideration is obsolescence. New ASIC generations can render earlier models unprofitable within one to two years. Some cryptocurrencies also use ASIC-resistant algorithms deliberately, meaning ASIC hardware cannot be used for them.

GPU miners

Graphics processing units (GPUs) can mine multiple different coins by switching algorithms, offering more flexibility than ASICs. However, GPU mining profitability declined sharply after Ethereum transitioned to Proof of Stake in September 2022, removing the largest GPU-mineable network from the market. Currently, GPU mining remains viable for a smaller set of coins including Ethereum Classic and Ravencoin, though profitability depends heavily on local electricity costs and the coin's current mining difficulty.

CPU miners

Central processing units (CPUs) are the least efficient mining hardware and are generally not competitive for major coins. A small number of cryptocurrencies use algorithms specifically designed to remain CPU-mineable, making CPUs a viable option for those coins only.

Types of Mining Arrangements

Solo mining

Solo mining means you compete against the entire network independently. If you find a valid block, you keep the full reward. However, the probability of doing so is extremely low for most major coins. On the Bitcoin network, where the combined hashrate runs into the hundreds of exahashes per second, a single ASIC represents a vanishingly small fraction of total network power. Solo Bitcoin mining is not a realistic option for most individuals.

Solo mining can still make sense on smaller networks with lower total hashrates, where an individual miner holds a more meaningful share of network power, but this also means the network and its coin carry higher risk.

Pool mining

A mining pool combines the hash rate of many participants and distributes rewards proportionally based on each member's contribution. This results in smaller but more frequent and predictable payouts compared to solo mining. Most pools charge a modest fee, typically between 1% and 2.5% of rewards. Pool mining is the practical default for most individual miners.

Cloud mining

In cloud mining, you pay a provider to mine on your behalf using their hardware. This removes the need to purchase equipment, manage cooling, or pay direct electricity bills. However, it introduces counterparty risk: you are dependent on the provider delivering the promised hash rate and paying out rewards as agreed. The cloud mining space has historically included a high proportion of fraudulent services, so careful due diligence is essential before committing funds to any cloud mining contract.

How to Mine Cryptocurrency: Step-by-Step

Step 1: Choose your coin

Different cryptocurrencies vary significantly in mining difficulty, hardware requirements, and potential returns. Larger networks such as Bitcoin require specialised ASIC hardware and are highly competitive. Smaller PoW networks may be more accessible for individual miners but carry higher volatility and project risk. Consider which hardware you already have access to, or can afford, and research which coins are compatible. Always do your own research (DYOR) before committing capital.

Step 2: Calculate electricity costs first

Electricity is the primary ongoing cost of mining and the most important variable in whether an operation is viable. Before purchasing hardware, check your local electricity rate per kilowatt-hour and use a profitability calculator such as WhatToMine or the NiceHash profitability calculator to estimate whether projected mining revenue is likely to cover your costs at current difficulty and coin prices. The same hardware can be highly profitable in one location and deeply unprofitable in another depending solely on the electricity rate.

Step 3: Choose and acquire mining hardware

Select hardware suited to the coin you have chosen. For Bitcoin, current-generation ASICs are the standard option. For ASIC-resistant coins, a GPU rig may be appropriate. Factor in the total cost including the unit itself, power supply unit, cooling equipment, and any shelving or enclosures. Be aware that hardware can depreciate quickly as newer, more efficient models become available.

Step 4: Set up a crypto wallet

You will need a crypto wallet to receive mining rewards. When configuring your mining software, you will specify a wallet address where the rewards are sent. Use a wallet you control directly rather than an exchange deposit address, as exchange policies on direct mining deposits vary and some do not accept them.

Step 5: Download and configure mining software

Mining software connects your hardware to the network or mining pool. Most software is available free of charge from the official website of the cryptocurrency you intend to mine. For pool mining, your software will also need the pool's connection address and your worker credentials. Common software options include CGMiner and BFGMiner for ASICs, and various GPU-specific miners depending on the algorithm. Review the documentation for your chosen software carefully and verify downloads from official sources to avoid malicious versions.

Step 6: Join a mining pool (recommended for individuals)

For most miners, joining a mining pool is the practical choice over solo mining. When evaluating pools, consider the pool's fee structure, minimum payout threshold, payment method, and track record for reliability. Larger pools provide more consistent payouts, while smaller pools offer a higher payout per block if found, but less frequently.

Step 7: Monitor and maintain your operation

Once running, monitor your hardware's temperature, hash rate output, and power consumption regularly. Mining rigs generate significant heat and noise, so adequate ventilation and cooling are important for hardware longevity. Keep mining software updated to ensure compatibility with network protocol changes. Review your profitability periodically, particularly after network difficulty adjustments or significant changes in the coin's market price.

Is Cryptocurrency Mining Worth It?

Whether mining makes financial sense depends on a combination of factors: your electricity cost, the hardware you use, the current mining difficulty, the block reward structure, and the market price of the coin. These variables change over time, and a mining setup that covers its costs in one period may not in another.

Transaction fees from on-chain activity, including Ordinals and Runes inscriptions, have become a growing component of miner revenue alongside block subsidies, but this income stream is variable and not guaranteed.

Some people mine cryptocurrency primarily to contribute to the decentralisation and security of a PoW network rather than for financial return. That is a legitimate reason to mine, though the costs involved are still worth understanding fully before starting.

Note that a 51% attack becomes more feasible on smaller networks with lower total hash rates. Miners on smaller chains should be aware that network security is directly linked to the total computing power participating.

Will Mining Be Profitable for Me?

Use a mining profitability calculator (such as WhatToMine) and input your hardware's hash rate, power consumption, and your electricity rate. Compare the projected daily revenue against your daily electricity cost. Note that profitability can change as mining difficulty adjusts and coin prices move, so calculations should be revisited regularly rather than treated as fixed.

Closing Thoughts

Cryptocurrency mining is a multifaceted endeavor that requires careful consideration of hardware, electricity costs, and network conditions. Through choosing the right hardware, evaluating profitability, and implementing sound risk management strategies, miners can navigate the complexities of the space. As mining difficulty and coin prices change continuously, staying informed and adaptable is essential to maintaining a profitable mining operation.
