Antminer S21+

A modern mid-range model released in February 2025, with a hashrate of 216 TH/s and impressive energy efficiency of 16.5 W/TH! Bitmain, the global leader in mining equipment, has launched an inexpensive air-cooled miner with features that previously seemed unattainable in this class. The launch of such a model at the beginning of a new halving cycle is great news for those who intend to earn the most over the next three years, and possibly maintain profitability even after the 2028 halving! Bitmain is a proven manufacturer that provides the highest-quality miners, so there is no doubt that the S21+ can remain operational for more than three years!

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+ 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.

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+ = $1 760 / (Daily Income - Daily Electricity Fee)

Thus, the estimated payback period for Antminer S21+ is 592 days. 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 miners with Cuverse provides:

• Professional maintenance of miners in a sterile data center environment.
• Centralized supply and exhaust ventilation.
• Regular cleaning of the air ducts for every individual miner and the entire rack.
• Monitoring of the operating mode for each miner.
• Prompt replacement of any decommissioned hashing power.
• A fixed electricity cost for the entire contract duration.
• Continuous updates to the computational power (hardware).
• 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.

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!
