600K Bitcoin Miners Shut Down in Last 2 Weeks, F2Pool Founder Estimates

Between 600,000 and 800,000 bitcoin miners have shut down since mid-November amid declines in value and hashrate throughout the community, in accordance with the third-largest mining pool.

In an interview with CoinDesk, Mao Shixing, founding father of F2pool, stated his agency’s estimate takes under consideration the whole community hashrate drop and the common hash energy of older mining machines which can be having a tough time producing earnings.

In line with information from blockchain.data, the bitcoin community’s total hashrate, which captures the aggregated computing energy on the world’s first blockchain, has dropped from round 47 million tera hashes per second (TH/s) on Nov. 10 to 41 million on Nov. 24 – an nearly 13 p.c decline.

Mao defined most miners that will have halted operations are doubtless these utilizing older fashions, such because the Antminer T9+ made by Bitmain and AvalonMiner 741 by Canaan Artistic. These miners have a mean hash energy of round 10 TH/s and are estimated to be dropping cash proper now, in accordance with F2pool’s miner income index

The truth is, the bitcoin hashrate on F2pool, which now accounts for about 11.four p.c of the whole community, has additionally seen a decline of over 10 p.c in latest weeks, Mao stated.

“It’s onerous to calculate a exact variety of miners related to us that had unplugged. However we noticed over tens of 1000’s of them [shut down] in the previous a number of days primarily based on conversations we had with bigger farms that we’re in common contact with,” he stated, including:

“That is what’s occurring amongst miners in China.”

On Nov. 20, Mao shared through his Weibo social media account a photograph of a person packing pc gear into packing containers, with the caption “shutting down isn’t an choice, now should promote by the kilos.”

The put up was broadly taken to imply even mining tools of latest classic was being offered off by the kilogram in China, however Mao advised CoinDesk he was half-kidding when he wrote it, explaining:

“These miners being offered by the kilos are even older and out of date fashions that aren’t usable anymore. So persons are promoting to recycle [them] like copper as an alternative of for additional mining functions.”

Winter Is Coming

Stepping again, Mao stated there are a number of components that contributed to the shakeout amongst miners, together with the latest market decline that adopted the bitcoin money onerous fork on Nov. 15; a rise in electrical energy prices in China; and the truth that Chinese language producers are nonetheless racing to improve their merchandise, making older machines more and more uncompetitive.

“All these components are overlapping proper now which led to this latest phenomenon,” Mao stated.

Because the winter comes in China, hydropower crops are experiencing a dry season when electrical energy prices have doubled from what they might have been in the summer season when water was considerable.

Throughout the summer season, Mao stated, electrical energy prices in China’s mountainous Southwestern area, the place numerous mining farms reside, may go under zero.2 yuan, or $zero.029, per 1 KW/h. However right now of the yr, that’s going as much as above zero.three yuan ($zero.043).  

Whereas different fossil gasoline energy stations, as an example in China’s Xinjiang province, might generate electrical energy at a steadier charge, the general prices are nonetheless not less than about zero.28 yuan ($zero.04) per 1KW/h, Mao stated.

As bitcoin’s value just lately tanked to a 13-month low under $four,000, mining farms which were utilizing machines made in 2016 and 2017 with decrease productiveness simply can’t break even, Mao added.

To make certain, the truth that mining farms have unplugged doesn’t essentially imply they’re out of the sport utterly.

“Bitcoin mining is at all times a dynamically adjusted course of,” Mao stated, which means when the hashrate drops, so does the mining problem. The newest information reveals the bitcoin mining problem has already declined barely by 5 p.c throughout the previous a couple of days.

This dynamically adjusted course of may give those that haven’t thrown in the towel an incentive to stay round, Mao stated, concluding:

“The change of bitcoin’s mining problem usually has a lag of about 14 days [following hashrate change]. After this wave of shutdowns, these gamers who opted to remain in might have a greater life.”
