About Antminer S21 XP
A late 2024 model from Bitmain with a hashrate of 270 TH/s and energy efficiency of 13.5 W/TH. A new level of miner energy efficiency for successful mining under any market conditions! Powerful air-cooled fans, low noise, high reliability and increased profitability are the main components of success when working on equipment of this class. Even if the hashprice decreases, there’s no need to fear the increasing network difficulty or bitcoin exchange rate fluctuations! By choosing Antminer S21XP, you are choosing one of the leaders in profitability among miners!
Where will my miners operate?
Our data centers are equipped with professional cooling systems that maintain ideal temperatures year-round, regardless of external weather conditions. A properly cooled Antminer S21 XP ASIC miner generates the highest revenue because its chip will not throttle or fail due to overheating. Servicing ASIC miners in professional data centers represents the pinnacle of mining hardware care and, as a result, maximizes the profit from each machine.
Return on Investment
Investments in mining must pay for themselves and generate significant income for the investor. Each asic miner has a limited lifespan, constrained by its mean time between failures and the increasing market complexity, which demands constant improvements in the energy efficiency of mining equipment.
Calculating the payback period for each asic miner allows for comparing equipment on an equal footing and building mining portfolios based on the risks associated with various market scenarios. To estimate the payback period, divide the miner’s cost by its daily net profit to determine the number of days required for the miner to pay for itself.
Payback Period for Antminer S21 XP = $4 108 / (Daily Income - Daily Electricity Fee)
Thus, the estimated payback period for Antminer S21 XP is 981 day. This means that after this period, your miner will begin generating daily net profit. When estimating the payback period, it is crucial to consider that the Bitcoin network difficulty typically increases, and the size of daily mining rewards slowly decreases; however, this trend can be disrupted for extended periods. Additionally, the dollar-denominated income is significantly influenced by the Bitcoin exchange rate.
This approach allows for a comparative analysis of investment profitability across different models of mining hardware but should not be considered a precise tool for absolute figures.
Hosting tariff list
Our current rates start at $0.056 per kW in MAX mode and $0.035 in ECO mode.
Hosting miners with Cuverse provides:
- Professional maintenance of miners in a sterile data center environment.

- The ability to diversify investments within a mining equipment portfolio.
- Professional 24/7 technical support.
- A convenient dashboard for managing your mining from anywhere in the world at any time.
- A focus on the financial aspects of the project, not the technical details.
Cuverse handles the entire technical side of mining. Hosting miners with Cuverse allows you to profitably utilize our capacity, our mining infrastructure, and our expertise to make mining maximally profitable during market turbulence and to earn the maximum during favorable times.
Warranty
Miner hosting with Cuverse includes a 1-year manufacturer's warranty on ASIC miners, plus an additional 1-year warranty provided by Cuverse.
While operating in data centers, miners run at maximum load 24/7. However, regular professional maintenance allows each machine to operate beyond its rated lifespan. The extended miner warranty from Cuverse is a mark of equipment reliability, confidence in our capabilities, and the impressive industry experience of our Bitcoin mining specialists.
The miner warranty encompasses a complete range of measures aimed at ensuring zero downtime on the user's side, guaranteeing that not a single satoshi is lost due to equipment stoppage for any reason. Your ASIC miners in our hosting facility are always operational!
FAQ
- Antminer S21 XP has a hashrate of 270 TH/s. This allows Antminer S21 XP to remain profitable even during the most challenging market periods, such as when a drop in Bitcoin's price can halt mining on many inefficient farms. This leads to a decrease in the global Bitcoin network hashrate and, consequently, a reduction in network difficulty. Thus, engagement in mining forms a kind of hysteresis loop, shifted downward or upward on the scale of the Bitcoin network hashrate depending on macroeconomic data. In particular, US interest rates significantly influence the investment attractiveness of risky assets.
- Antminer S21 XP consumes 3.645 W. This means that the miner of this model has an energy efficiency of 13.50 W/TH. Energy efficiency indicates the profitability limit of a miner - the better the energy efficiency (the lower the parameter itself), the less energy the miner consumes to power its computational capacity. This is the so-called hashprice for a specific model in isolation. The more energy-efficient the mining equipment, the more it earns, all else being equal. However, such equipment is always more expensive, so when selecting it, you must be guided by your own risk management strategy. For example, you can assemble a mining portfolio from miners with different energy efficiency parameters to balance the total cost of the investment and its return.
- At the end of 2025, the Cuverse catalog features models of air-cooled miners. All of them are characterized by producing significant noise levels of around 75 dB. The Antminer S21 XP miner has a noise level of 75 decibels, equivalent to the noise of a busy street or the sound in a room filled with people engaged in lively conversation. The noise generated by ASIC miners during operation is a major red flag against housing the equipment at home, as living, and especially sleeping, under such conditions is impossible. Miners must be located in an isolated room additionally equipped with sound-absorbing materials.
- The miners used at Cuverse are modern mining machines with roughly uniform dimensions and weight. The Antminer S21 XP weighs 14.5 kg. This standard equipment weight allows for easy placement in racks and eliminates the need for frequent relocation. Once installed in its designated spot, a miner typically remains there for its entire long operational lifespan, stopping only for scheduled maintenance.
- All Cuverse miners utilize the SHA-256 algorithm, designed for mining Bitcoin and its forks. Cuverse is a Bitcoin company; we originally built Bitcoin mining infrastructure and continue to develop it regardless of market sentiment. Hosting equipment in our data centers is a rational investment in Bitcoin mining, offering a diversified approach to selecting miners.
- Miners in Cuverse data centers are connected in strict accordance with factory requirements to either single-phase or three-phase alternating current networks. The required input voltage for Antminer S21 XP is 200–240 V AC, with an allowable operating range of 180-264 V AC. The electrical grids of Cuverse data centers are equipped with surge protection systems, backup power systems, and continuous monitoring. Consequently, all miners are reliably protected from damage to their electrical components and premature failure due to power supply issues.
- The Antminer S21 XP has the following dimensions: 370 х 195.5 х 290 mm. The standardization of mining equipment sizes allows for the placement of various, yet model-similar, devices within the same racks. This does not hinder their centralized, regular maintenance.
- The Antminer S21 XP comes with a standard 1-year manufacturer's warranty, to which Cuverse adds an additional year of its own warranty coverage. We are confident in the equipment we use and have all the capabilities to extend its operational life through professional maintenance. In our data centers, miners perform optimally and fully utilize their intended lifespan without premature failure.
- Cashback is awarded as points when you pay for electricity. 1 point = $1. You can use cashback points to buy new miners or to cover your electricity bills. Check your cashback balance in your .
