The cryptocurrency market is inherently volatile, and this volatility directly impacts its foundational industry: mining. As a bull market progresses, crypto mining becomes an attractive entry point for traditional businesses looking to enter the digital asset space. This analysis provides a snapshot of mining rig profitability and the current state of mining pool concentration for the week.
Understanding the performance metrics of different mining hardware is crucial for anyone involved in or considering entering the crypto mining sector. The profitability of a mining rig is determined by several key factors, including its hash rate, power consumption, and the daily output of the cryptocurrency it mines.
Analysis of Mining Rig Profitability
For miners, the bottom line is earnings. Under constant electricity cost conditions—typically set by regional differences and individual mining farm agreements—a rig's return is calculated from its power efficiency, computational power, and daily coin production. The primary coins mined by dedicated hardware are Bitcoin (BTC) and Ethereum (ETH).
Based on publicly available data from manufacturers and using an average electricity cost of $0.37 per kWh (prices can be lower during the rainy season), the weekly ranking of the top 20 most profitable mining rigs and their manufacturers is clear.
A key trend emerged: Ethereum mining rigs demonstrated significantly higher returns than their Bitcoin counterparts. The top seven spots in the "daily average revenue" ranking were all occupied by ETH miners. This shift is largely attributed to the strong upward price movement of Ethereum during the period.
- Ethereum Mining Leaders: Among ETH rigs, models from Innosilicon delivered the best performance in terms of daily earnings.
- Bitcoin Mining Landscape: While the WhatsMiner M30S++ from MicroBT was the highest-earning Bitcoin-specific rig, analysis showed that models from Bitmain, particularly the Antminer S19 Pro, offered a superior cost-to-performance ratio. It's worth noting that several of Bitmain's most popular models were reported as sold out.
This performance review highlights the competitive landscape. Well-known Chinese mining firms like Bitmain, Canaan, and MicroBT continue to lead in hardware efficiency, despite other companies like Ebang International, The9, and 500.com being publicly listed in the U.S.
The Centralized Nature of Mining Pools
The development of mining pools represented a significant evolution for the crypto industry. In simple terms, a mining pool is an automated platform where individual miners combine their computational resources to increase their chances of successfully mining a block and earning rewards, which are then distributed based on contributed hash power.
Analysis of data from the week reveals a high concentration of computational power within a small number of major pools for both Bitcoin and Ethereum networks.
Bitcoin Mining Pool Distribution
The vast majority of Bitcoin's hash rate was controlled by a handful of pools, including F2Pool, Binance Pool, BTC.com, Poolin, and AntPool. Data from OKLink showed that these top pools were responsible for the overwhelming majority of blocks mined (a process known as "finding a block" or "block discovery") during this period.
Ethereum Mining Pool Distribution
A similar pattern of concentration was observed on the Ethereum network. Pools like SparkPool, Ethermine, and F2Pool commanded the largest shares of the total network hash rate. Consequently, these pools also accounted for the highest number of blocks validated.
This centralization stems from the probabilistic nature of Proof-of-Work mining. As the Bitcoin white paper explains, the network aims to produce one block every ten minutes. However, the chance of a single miner finding a block is incredibly low and is proportional to their share of the total network's computational power. For a individual with a single rig, it could take years to ever find a block solo.
Pools solve this by allowing participants to contribute hash power and receive a proportionate share of the steady, smaller rewards from every block the pool finds. This week's data confirms that this critical infrastructure remains in the hands of a few major players, with the Bitcoin network's average hash rate reaching 154.37 EH/s at a difficulty of 20.61 T.

Frequently Asked Questions
What determines a mining rig's profitability?
Profitability is primarily a function of the cryptocurrency's price, the rig's hash rate, its energy consumption (efficiency), and the cost of electricity. A higher hash rate increases potential earnings, while lower power consumption reduces ongoing costs.
Why were ETH miners more profitable than BTC miners this week?
The primary reason was the stronger positive price performance of Ethereum compared to Bitcoin during this specific period. Higher coin prices directly increase the value of the daily mining output, boosting revenue for miners of that asset.
What does "daily average revenue" mean in mining?
It refers to the average daily profit from mining after deducting the electricity cost from the value of the coins mined. It is a key metric for comparing the financial performance of different mining rigs.
Why is mining power concentrated in a few large pools?
Larger pools can offer smaller miners more consistent and predictable earnings by pooling their resources. This makes them attractive, leading to a feedback loop where successful pools attract more miners, further increasing their size and influence.
What is a "shutdown price" for a miner?
This is the price at which the value of the mined cryptocurrency equals the cost of the electricity required to run the machine. If the coin's price falls below this level, mining becomes unprofitable, though some miners may continue operating at a loss for strategic reasons.
Note on Data: This analysis relies on publicly available data from the period. The mining sector is dynamic, and specific figures for rig profitability and pool dominance can change rapidly with market conditions, network difficulty adjustments, and hardware advancements.
