Antminer S21+ Hyd 358T, with its ultra-high computing power of 358 TH/s and extreme energy efficiency of 16 J/TH, has become the "gold-mining artifact" in the eyes of miners today. As a new generation of water-cooled mining machine launched by Bitmain, it not only breaks through the performance bottlenecks of traditional air-cooled mining machines but also leads the industry towards an efficient and sustainable direction with its low-carbon, silent, and intelligent O&M characteristics. Below, we provide a comprehensive analysis of this mining machine's core competitiveness from the perspectives of performance, technology, and market adaptability. The noise level is as low as 28-50 decibels (under different operating conditions). The Antminer S21+ Hyd 358T disrupts the industry with its 358 TH/s computing power and 16 J/TH energy efficiency. Water-cooled heat dissipation combined with intelligent O&M achieves silence and low carbon emissions, while dynamic overclocking and extreme environment adaptability help miners withstand the risk of the halving, making it a powerful tool to ensure returns in a highly competitive era.

Customer FAQs
How long does it take to mine a Bitcoin?
The mining machine is calculated based on its daily output revenue, the time required to recover the investment cost of the mining machine, and the return rate, which is more valuable. There are many factors to consider when mining a coin, and it cannot be simply stated in one sentence!
Can I pick up the machine myself?
Yes, we offer self-pickup options. We have warehouses in Hong Kong, and the United States, so you can choose the nearest location based on your needs. Alternatively, we can also ship the machine to your forwarder's address.
Are miners purchased through you new?
Yes, we only sell brand new, factory-sealed miners. Apexto Team purchases equipment directly from the factory, ensuring all products are new and unused.
Typically, miners are shipped directly from the warehouse without opening the packaging. We only open the packaging for testing if requested by the customer before shipment.
