The Second Batch of AntMiner S4 2TH/s 

Only Available at bitmaintech.com

The enormously powerful and power efficient AntMiner S4 2TH/s is now available for sale globally.


The AntMiner S4 is the fourth generation Bitcoin mining rig by Bitmain. It uses the state of the art BM1382 chip powered by the 28nm tech process with ultra-low power consumption.

Power efficiency progress is reflected from the S1 to the S4 and is our focus to improve your investment and save on electricity bills.

The AntMiner S4 is built into 3U size box, although its hashrate is twice that of the S2. The S4’s design is hugely improved from S2’s experiences, using less hash blades and adjusting the space structure in each box to bring a light and portable model. It will be very convenient to deploy.

Notification for S2 Upgrade Kit - Coupons being issued

To all customers that ordered AntMiner S2s: We analysed the business case for S2 upgrade kits for end users and determined that it would not be worthwhile for either party.
* The S4 runs at 0.69 W/Gh/s power efficiency, which is significantly improved compared with the S2’s 1W/Gh/s. Even though the upgrade kits used the newest BM1382 chips manufactured at 28nm process, it was not a significant leap in power efficiency.
However, the next generation chip is more likely to be worth doing upgrade kits with.
* The S2 is still profitable to run for the next several months with its 1W/Gh/s power efficiency and so now is not a good time to replace them.

Coupons will be issued to express our sincere thank you for supporting Bitmain over the year. Each coupon has a value of $200 and will be issued for each S2 unit purchased. These coupons are only applicable for the purchase of S4s and only one coupon can be used per S4.
