The Bitcoin network difficulty increased by 3.60 % on August 24, to take the difficulty to 17.56, which is once again an all-time high. Network hashrate and Bitcoin price has been relatively flat, hovering between 120 – 127 EH/s and $11,200 – $11,700.
🎛 New Hardware
Innosilicon has launched a new Ethereum miner – the A10 Pro. It has a computing speed of 500 MH/s and consumes 860 watts. It’s already shipping by resellers out of Shenzhen.
StrongU has launched a series of new SHA256 miners – the Hornbill H8 and H8 Pro. They have a computing speed of 74 TH/s and 84 TH/s respectively, with a power consumption of 3,300 watts and 3,600 watts. It’s expected to start shipping between the end of October and mid-November.
MicroBT, Bitmain and Canaan have sold a significant amount of their new-gen SHA 256 ASIC stock. There are still machines available from resellers in Shenzhen, including S19 Pro, S19, M31S+, M31S and M32 machines.
🇨🇳 Mining in China
As reported by Wolfie Zhao of Coindesk, more than 20 Bitcoin mining farms in Inner Mongolia, China have been stripped of electricity perks after a clampdown by the local government.
The list issued by the local government includes subsidiaries of mining manufacturers Bitmain and Ebang.
It’s unlikely that this will have a huge impact in the short term for miners in China. Inner Mongolia has always been unpredictable from the regulation front, and there is a much greater number of large mining farms operating in Sichuan and Xinjiang. – Thomas
Mining in Sichuan continues to be unpredictable. Sichuan is a region prone to natural disasters, and almost every year there is flooding or earthquakes that impact the region.
During August there were a number of outages caused by rain and flooding. Cheaper electricity (~0.23 RMB/kWh) during hydro season is always offset by the uncertainty of uptime.
Bixin has launched a new Bitcoin mining pool named Kele pool. It can be found through the Bixin Wallet. It currently has around 850 PH/s on the pool. This is not the first foray by Bixin in the mining pool industry, as they operated a mining pool from 2016 to 2019.
🇺🇸 🇨🇦 Mining in USA and Canada
There have been some movements by publicly traded companies in the USA.
Marathon announced an installation of 1,360 new-gen ASIC miners: 700 WhatsMiner M31S+ and 600 S19 Pro Antminers. The current total hashrate of Marathon is 186 PH/s from 2,060 machines. They have another 1,000 S19 Pro miners coming between now and the end of year, which will take their total hashrate to 286 PH/s.
Marathon has also signed a long-term purchase agreement with Bitmain to receive 10,500 S19 Pro miners between January 2021 and June 2021. This would increase their hashrate by 1,155 PH/s and take them to approximately 1,441 PH/s in total.
Marathon also announced a letter of intent to acquire Fast Block for $22 million in Marathon shares. After deploying Fastblock’s 3,304 ASIC miners, Marathon’s hashrate will increase by 208 PH/s, and also allow Marathon to take advantage of Fastblock’s competitive energy prices of $0.0285/kWh.
Riot Blockchain has announced the purchase of 13,100 S19 Pro miners from Bitmain. These will be deployed in the first half of 2020. RIOT currently has 456 PH/s and is expecting 1,000 S19 Pro’s in November that would take their hashrate to 566 PH/s. Once the 13,100 S19 Pro’s arrive by June 2021, the company is expecting to have a total hashrate of 2,007 PH/s.

🌏 Mining around the Globe
Something peculiar happened during the week, as BTC.com suddenly added 7 EH/s of hashrate. Although it was suggested that this may be related to Bitmain having large sales of the S19 Pro recently, this was not the case.
The abnormal jump was caused by Minebest/Mining City directing hashrate from BTCV to BTC for a period of time.
Enegix announced their monster 180 MW facility in Ekibastuz, Kazakhstan is ready to launch in September, 2020. This is their third facility in Kazakhstan and Enegix is currently looking for hosting clients, and it can hold around 50,000 new-gen machines.
