How to mine cryptocurrencies in 2025: a complete step-by-step guide (ASIC, Kaspa, Alephium, costs, pools)
Cryptocurrency mining is a narrow-margin business today. The price of electricity, the choice of algorithm, and the efficiency of the machine are decisive. After the halving in 2024, the reward for Bitcoin is 3,125 BTC and fees vary depending on network traffic.
How mining works in a nutshell
A mining machine searches for a solution to a mathematical problem so that the resulting hash satisfies the network conditions. A successful find brings a reward — newly created coins and transaction fees. The difficulty is continuously adjusted according to the overall network, so the returns fluctuate.
ASIC or GPU — which way to go
ASIC: specialized equipment, high efficiency for a specific algorithm, low flexibility. Ideal for Bitcoin and other algorithms where there are verified ASICy.
GPU: more versatile, can mine different coins. Good if you want to quickly switch between projects. However, the performance per watt is usually worse than ASIC.
What to mine in 2025
Bitcoin (BTC) — competitive environment, requires modern ASICand low electricity costs.
Kaspa (KAS) — a growing ecosystem, suitable for both GPU and dedicated solutions; low pool latency is important.
Alephium (ALPH) — new player for some algorithms, it is recommended to follow official configurations and manufacturer recommendations.
Pool or solo mode?
Solo mining is high-risk and requires a huge hashrate. Pools distribute the reward based on share and provide more stable income. When choosing a pool, look for low fees, reliable payouts, and servers close to your location.
How to calculate profit
Required data: device hashrate, power consumption in kW, electricity price per kWh, pool fee, coin exchange rate. Always include the real price of electricity and a reserve for outages in the calculation. Subtract operating costs (electricity, pool fee, service) from gross earnings. It is recommended to add 3–4% as a reserve for fees and unexpected losses.
Practical step-by-step procedure
-
Choose a coin according to your strategy — long term BTC or speculatively altcoins.
-
Choose hardware by algorithm — compare performance/watt.
-
Prepare your wallet and back up your access data.
-
Select a pool, set a stratum URL, worker name, and payout address.
-
Start the device, monitor the temperatures and reject/share ratio.
-
Monitor monthly returns and adjust settings based on actual data.
What to look out for in traffic
-
Temperature and cooling — overheating reduces lifespan.
-
Power quality and UPS — outages are expensive.
-
Dust and maintenance — regular cleaning extends the lifespan.
-
Rejected and stale shares — indicate network or configuration problems.
Tips for better returns
-
Cheap electricity will significantly improve margins. Consider hosting in a low-cost location.
-
Monitor pool fees and spread your risk across multiple pools if you have multiple devices.
-
After the halving, efficiency and stability are more important than maximum short-term performance.
Common beginner mistakes
-
Not counting the real costs of cooling and servicing.
-
Ignoring pool fees and transfer fees.
-
Confidence in maximum hashrate without verification of stability and processed shares.
