Hey everyone! There's some exciting news coming out of the mining world. Bitmain, a leading manufacturer of Bitcoin mining equipment, is set to unveil its latest model, the Antminer S21, during the World Digital Mining Summit 2023 (WDMS) in Hong Kong on September 22nd and 23rd.
What makes the Antminer S21 stand out? Well, according to Bitmain's announcement, this will be the first ASIC with an energy efficiency ratio of less than 20J/T. For those who might not be familiar, energy efficiency is a critical factor in Bitcoin mining profitability. The electricity cost is one of the primary operational expenses in the mining industry. An energy scale of 20 J/T means the device consumes 20 joules for every terahash of hashrate it produces.
Bitmain has been on a journey of increasing efficiency. With the Antminer S9, they broke the 100 J/T barrier for the first time. This was followed by a series of increasingly efficient miners like the S19 (34.5 J/T), S19 Pro (29.5 J/T), S19 XP (21.5 J/T), and the S19 XP Hyd (20.8 J/T).
This year's WDMS event is themed "Mining for the Bull Market," reflecting a bullish sentiment contrasting the market scenario from November 2022. Attendees can look forward to exclusive benefits such as loyalty point programs, credit lines, and special discount coupons for equipment purchases.
Another interesting fact: Bitmain chose Hong Kong as the venue for WDMS 2023 due to its crypto-friendly regulations, after being in Cancún, Mexico last year.
For those interested in the specifics of the new models:
- Antminer S21 ($5,800.00)
- Antminer S21 Pro ($7,000.00)
What are your thoughts on this?

Extra calculations in case you're curious:
Based on the information from the Minerstat mining calculator, the Antminer S21 Pro model, with its 250 TH/s hashing power, can mine approximately 0.02300 BTC per month given the current network conditions, assuming free/green energy.
- Hashrate: 250 TH/s
- Estimated BTC mined per month: ~0.02300 BTC
This means, the Antminer S21 Pro model can mine approximately $676.2 worth of BTC per month at the current BTC price of $29,400.
So, it would take approximately 10 months to achieve ROI for the Antminer S21 Pro, ASSUMING the BTC price and mining difficulty remain constant and there are no additional costs.
