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


Between 600,000 and 800,000 bitcoin miners have shut down because mid-November amid declines in value and hashrate throughout the community, according to the third-major mining pool.

In an job interview with CoinDesk, Mao Shixing, founder of F2pool, mentioned his firm’s estimate will take into account the full community hashrate fall and the common hash power of more mature mining devices that are acquiring a hard time creating profits.

According to details from blockchain.facts, the bitcoin network’s entire hashrate, which captures the aggregated computing power on the world’s first blockchain, has dropped from all over 47 million tera hashes per second (TH/s) on Nov. 10 to 41 million on Nov. 24 – an pretty much 13 percent drop.

Mao described most miners that may perhaps have halted functions are very likely those people making use of more mature designs, this kind of as the Antminer T9+ designed by Bitmain and AvalonMiner 741 by Canaan Creative. These miners have an common hash power of all over 10 TH/s and are estimated to be shedding revenue suitable now, according to F2pool’s miner revenue index

In simple fact, the bitcoin hashrate on F2pool, which now accounts for about 11.4 percent of the full community, has also observed a drop of about 10 percent in the latest weeks, Mao mentioned.

“It’s hard to work out a precise selection of miners related to us that experienced unplugged. But we saw about tens of thousands of them [shut down] in the earlier numerous times dependent on conversations we experienced with bigger farms that we are in regular speak to with,” he mentioned, adding:

“This is what’s happening amongst miners in China.”

On Nov. 20, Mao shared via his Weibo social media account a picture of a guy packing computer system gear into boxes, with the caption “shutting down is not an possibility, now have to provide by the kilos.”

The put up was greatly taken to imply even mining products of the latest classic was currently being bought off by the kilogram in China, but Mao explained to CoinDesk he was fifty percent-kidding when he wrote it, describing:

“Those miners currently being bought by the kilos are even more mature and out of date designs that are not usable anymore. So people today are providing to recycle [them] like copper as an alternative of for further mining purposes.”

Winter season Is Coming

Stepping again, Mao mentioned there are numerous factors that contributed to the shakeout amongst miners, including the the latest marketplace drop that followed the bitcoin dollars hard fork on Nov. 15 an improve in electrical power fees in China and the simple fact that Chinese suppliers are even now racing to enhance their solutions, making more mature devices progressively uncompetitive.

“All these factors are overlapping suitable now which led to this the latest phenomenon,” Mao mentioned.

As the wintertime arrives in China, hydropower vegetation are suffering from a dry time when electrical power fees have doubled from what they would have been in the summertime when drinking water was ample.

All through the summertime, Mao mentioned, electrical power fees in China’s mountainous Southwestern area, where plenty of mining farms reside, could go underneath .2 yuan, or $.029, per 1 KW/h. But at this time of the year, that is heading up to earlier mentioned .3 yuan ($.043).  

While other fossil gasoline power stations, for occasion in China’s Xinjiang province, may perhaps make electrical power at a steadier fee, the total fees are even now at least about .28 yuan ($.04) per 1KW/h, Mao mentioned.

As bitcoin’s value recently tanked to a 13-month small underneath $4,000, mining farms that have been making use of devices designed in 2016 and 2017 with decreased productiveness just just cannot break even, Mao added.

To be guaranteed, the simple fact that mining farms have unplugged does not essentially imply they are out of the sport absolutely.

“Bitcoin mining is usually a dynamically altered method,” Mao mentioned, indicating when the hashrate drops, so does the mining issue. The newest details reveals the bitcoin mining issue has by now declined marginally by 5 percent in just the earlier a handful of times.

This dynamically altered method could give those people who have not thrown in the towel an incentive to stick all over, Mao mentioned, concluding:

“The alter of bitcoin’s mining issue usually has a lag of about 14 times [following hashrate change]. After this wave of shutdowns, those people gamers who opted to remain in may perhaps have a much better life.”
