What is Bitcoin mining?

Bitcoin mining is the process of using specialized computer hardware (ASICs) to validate transactions and secure the Bitcoin network. Miners compete to solve cryptographic puzzles using the SHA-256 algorithm, and successful miners receive block rewards in Bitcoin. As of 2024, the block reward is 3.125 BTC following the April 2024 halving.

What is an ASIC miner?

ASIC (Application-Specific Integrated Circuit) miners are specialized hardware designed specifically for Bitcoin mining. They are significantly more efficient than general-purpose computers for performing the SHA-256 hash calculations required for mining. Major manufacturers include Bitmain (Antminer) and MicroBT (Whatsminer).

How does Bitcoin mining difficulty work?

Bitcoin's mining difficulty automatically adjusts every 2016 blocks (approximately every 2 weeks) to maintain an average block time of 10 minutes. If more miners join the network and blocks are found faster, difficulty increases. If miners leave and blocks slow down, difficulty decreases.

What is a mining pool?

A mining pool is a group of miners who combine their computing power (hash rate) to increase the probability of finding blocks. When the pool successfully mines a block, the rewards are distributed among participants based on their contributed hash power. Common payment methods include PPS (Pay Per Share), PPLNS (Pay Per Last N Shares), and FPPS (Full Pay Per Share).

What is hash rate in Bitcoin mining?

Hash rate measures the computational power used in mining, typically expressed in terahashes per second (TH/s) or exahashes per second (EH/s) for the entire network. Higher hash rates increase the probability of finding valid blocks. Modern ASIC miners can achieve hash rates of 100+ TH/s.

What is the current Bitcoin block reward?

As of 2024, the Bitcoin block reward is 3.125 BTC per block, following the halving event in April 2024. Bitcoin undergoes a halving approximately every 4 years (every 210,000 blocks), reducing the block reward by 50%. The next halving is expected around 2028, when the reward will decrease to 1.5625 BTC.

How is mining profitability calculated?

Mining profitability depends on several factors: hash rate (TH/s), power consumption (watts), electricity cost ($/kWh), Bitcoin price, and network difficulty. The key metric is efficiency, measured in Joules per Terahash (J/TH). Lower J/TH means more efficient mining. Profitability = (Hash Rate × Hash Price) - (Power Consumption × Electricity Cost).

Bitcoin Mining Laws in Germany

Overall status: Legal. Mining legal. Following MiCA, the German implementing law (FinmadiG/KMAG, in force 30 Dec 2024) replaces the legacy KWG crypto-custody licence with a MiCA CASP framework supervised by BaFin.

Legal Status — Legal

Mining legal. Following MiCA, the German implementing law (FinmadiG/KMAG, in force 30 Dec 2024) replaces the legacy KWG crypto-custody licence with a MiCA CASP framework supervised by BaFin.

Updated 2026-01-01

Licensing — Restricted

No licence for solo mining. Commercial mining services, pools and MaaS providers need BaFin MiCA CASP authorisation by 31 Dec 2025 under the German short-form transitional path (vs. 1 July 2026 EU default).

Updated 2026-01-01

Taxation — Restricted

BMF guidance (May 2022, updated 2025): mining rewards = commercial income (Gewerbebetrieb) for systematic activity; private mining one-year holding rule no longer applies after 2024 amendments.

Updated 2026-01-15

Environmental — Restricted

BImSchG noise/air permits and EnEfG (Energy Efficiency Act 2023) reporting apply to data centres >2.5 MW; PUE and waste-heat-reuse requirements tighten through 2026-27.

Updated 2026-01-01

Energy — Restricted

Some of the highest industrial electricity prices in the EU (>€0.20/kWh in 2026); Netzentgelte (grid fees) reform makes flexible-load tariffs more available but not specific to mining.

Updated 2026-01-15

Import/Export — Legal

ASIC imports legal under EU customs / CE / EMC rules.

Updated 2026-01-01

Banking — Restricted

Standard EU banking with DORA/AMLA compliance. BaFin maintains tight onboarding scrutiny of crypto-related corporate accounts.
