After halving in Bitcoin earlier in the week, 45 mining devices were no longer available.

Bitcoin’s block reward halving was completed on May 11, and block rewards of 12.5 BTC were reduced to 6.25 BTC. In an analysis published in 8BTC and created with the contributions of the world’s largest mining pool F2Pool, it is stated that approximately 45 old mining devices have been unplugged overnight since the award was halfway.

These models burn mobile

The best among all unprofitable mining devices is Bitmain’s Antminer S11. With a power of 20.5 TH per second, this device is currently damaging $ 0.09 a day against an energy cost of $ 0.049 per kilowatt hour. Other mining models that do damage based on this cost include Bitfure Tardis, Antminer S9 SE, GMO Miner B2, Innosilicon T2 Turbo, Bitfily Snow Panther B1, Canaan Avalonminer 921 and the popular Antminer S9. The B8 model of Bitfury, which was released in 2017 after the split, loses more than $ 3 a day.

As a matter of fact, all these mining device models were seen to have a drop in hash rate, which was losing money. After the halving took place, Bitcoin’s hash rate experienced a near 30 percent retreat.

On the other hand, it is stated that some mining companies in China, Central Asia and Iran are able to supply energy for free or at a very cheap cost of $ 0.02. According to AsicMinerValue, there are 8 unprofitable models for these businesses. These include Whatsminer M3X, Avalonminer 741, Whatsminer M3, Antminer S7-LN, Antminer S3, Antminer V9, Antminer S7 and Antminer S5. These devices cost $ 0.09 to $ 0.19 a day, based on current prices.

None of the selling Antminer S9s do not face

In addition, Antminer S9 devices, which sold for a period of time, suffered great depreciation in the second hand market. It is claimed that this model can only find buyers for $ 14. Not so much, a few years ago, S9s made up more than 70 percent of the hash rate. The news in 8BTC also noted that a mining business with 8,000 devices in Sichuan province was sold a week before the halving event. The owner of the business, Zhou Wenbo, stated that the buyer is not willing to buy older generation Antminer S9s, Avalonminer devices and Innosilicon Terminator 2 models.
Very profitable

Finally, there are many models that can make a lot of profit with the current Bitcoin price. Bitmain Antminer S19 Pro, S19, S17 +, MicroBT Whatsminer M30S are some of them.
