Product Description

S15 28T Antminer BTC Miner SHA256 BTC BCH second hand​ ​:




Antminer S15 is equipped with Bitmain 7NM chip, a single chip that integrates 1 billion transistors, and the performance is greatly improved. The computing power is as high as 28T, and the high performance is more durable. The energy efficiency ratio is 57J/T, saving energy and electricity.

The fans are designed in parallel and adopt a new heat dissipation structure, which shortens the air path and reduces power, improves heat dissipation, and reduces operation and maintenance costs.

Standard or low-power mode, which can satisfy both miners who pursue performance and miners who need energy saving.

Q: Is the actual product the same as the product picture?

A: Due to the frequent replacement of mining machines, the manufacturer may modify the appearance and packaging of the machine without notice. Therefore, the goods you receive may not be exactly the same as the pictures and product descriptions. Please use the actual product you received. We will update the product description in time and ensure that the nominal computing power is accurate. Please forgive me for the inconvenience caused, thank you!


Q: Can the mining revenue be guaranteed?

A: Because there are too many factors that affect mining income, we cannot guarantee your income. If you are interested, you can use the mining income calculator to estimate the income.


Q: What is the payment method?

A: We currently only accept USDT payment


Q: Who is responsible for the tax?

A: The buyer is responsible for any taxes.




We have 2 BTC mining farms built by ourselves, have our own professional operation and maintenance personnel, and cooperate with multiple maintenance centers. Before the mining machine is shipped to you, we will test the mining machine and send the test video to you to ensure that the mining machine in your hands can operate normally and minimize the loss of transportation.
