Bitcoin’s Accelerating Hashrate

22,243

On August 19, the combined SHA-256 hashrate between the BCH and BTC networks touched a massive high of over 91 exahash per second (EH/s). One notable contribution to today’s network hashrates is the manufacturing of next-generation mining rigs that produce a significant number of terahash. Currently, the top machine released this summer is Pangolin’s Microbt Whatsminer M20S, generating a whopping 70-72 terahash per second (TH/s).

Bitcoin’s Hashrate Keeps UP

After the birth of application-specific integrated circuits (ASICs) built for the SHA-256 consensus algorithm (BTC, BCH), the landscape of manufacturers has looked very different. Even over the course of the last two years, mining producers have changed substantially except for Bitmain, which has managed to survive through every stage. The top mining rig creators in 2019 include companies like Bitmain, Pangolin, Innosilicon, Ebang, Asicminer, and Canaan.

The combined SHA-256 hashrate between BCH and BTC is steadily approaching 100 exahash per second.

Pangolin, Innosilicon, Bitmain, and Strongu have all produced new miners in 2019. The top mining rig this month is the new Pangolin Microbt Whatsminer M20S, a machine that produces 68-70TH/s at top speeds. Unlike most of the manufacturers located in China, the Shenzhen Bit MicroelectronicsWhatsminer M20S hasn’t sold out yet. The unit consumes about 3360W off the wall and its two fans have a higher sound level than most competitors as the M20S generates 75db.

The Whatsminer M20S model from Pangolin/Microbt mining performs at 68 to 70TH/s with a power consumption of 3360W off the wall. The M20S version uses TSMC-created 12nm semiconductors.

The M20S has TSMC wafered 12nm chips powering the devices. Pangolin is known for creating machines that produce competitive hashrates but with different sized chips. More than a year ago when companies like GMO and other manufacturers were seeking to score 7nm chips, Pangolin was still using 28nm and 16nm chips. However, the Whatsminer M3 and M10 produced between 12TH/s to 33TH/s using those chips. Pangolin may have got a deal on the 12nm chips as TSMC had slow orders on the 12nm and 8nm in April. According to the business, there have been six batches of Whatsminer M20S models sold so far. Each device is $2,629, and at $0.13 per kWh, the device makes between $9-11.50 a day at current BTC prices and network difficulty. Today, at a price of $318-325 per BCH plus the difficulty (287,507,454.73), profits can fluctuate between -2% to +2% processing either the BTC or BCH chains. The new Whatsminer M20S has received good reviews in comparison to the Asicminer 8 Nano Pro which was released in May 2018.

The new Whatsminer M20S has received decent reviews online and there’s a few filmed performance tests as well. Unlike the Asicminer 8 Nano Pro there are resellers on the second market for Pangolin/Microbt brand devices.

Three Antminer Models With More Than 50 Terahash

Statistics show that the Asicminer 8 Nano Pro would be the second most powerful SHA-256 miner with 76TH/s per unit. However, the company is completely sold out and second market reviews are not very good. In fact, there are videos and reviews online warning people not to invest in the Asicminer 8 and the 8 Nano Pro. There are no second market resellers and nearly all the reviews stemming from every Asicminer product in existence have been negative. With a machine launched last year that costs $11,600 per unit and requires a minimum order of five units, it seems most mining operations did not invest in this model.

Bitmain’s Antminer S17 series produces between 50 to 56TH/s depending on the model. Reviews are good, the company is still shipping batches and there are second market resellers as well.

Following the Asicminer statistics, the next three miners in the top five are manufactured by Bitmain, namely the Antminer S17 Pro series (55TH/s), S17 (56TH/s), and the 50TH/s S17 Pro version. The three new Ant-miners pull in around $7-10 per day with electricity rates at $0.14 per kWh.
