Actual ASIC miners for bitcoin mining in 2021

The renewed interest in cryptocurrencies in 2021 pushed Bitcoin prices back to new heights, which in turn influenced the mining income of this cryptocurrency. Bitcoin miners again began to buy out-of-date ASIC miners Antminer S9 2016, because even they have begun to bring relatively good profit compared to the fact that a few months ago they did not even recoup the cost of electricity. And this is not to mention the more modern ASIC models SHA-256, which are several times more powerful and energy efficient than the S9. Next, we will consider all the currently relevant ASIC miners for mining bitcoin in 2021, which you can purchase. Next, we will compare the hashrate, power consumption and income of SHA-256 ASIC miners, so that you can better navigate the models and firms of manufacturers of various ASICs.

To make the information more visual, we will group all Bitcoin ASIC models by company and year of production in a tabular form:

* The calculation of the income from Bitcoin mining was made on March 10, 2021 (BTC: 53,700 USD)

** The percentage indicates how much you need to pay for electricity from income at an electricity price of USD 0.05 per kilowatt.

The table shows the most popular brands and models that can be found on sale. But besides them, there are lesser-known companies that also produce ASIC miners for Bitcoin mining: BitFury, Cheetah, ASICMiner, HummerMiner, Alladin, STRONGU, Ebang, Pantech, Holic, GMO.

The cost and payback of mining equipment were not given because to find on sale, and even more so at the manufacturer's recommended price, ASIC miners are now not possible and prices can vary greatly depending on the seller. It is also not possible to buy SHA-256 ASICs directly from the manufacturer, because all companies sold their products a year in advance on pre-orders in large quantities. Therefore, now you can buy ASICs only from resellers or individuals, and this applies to old models of the 2016-2018 sample. Almost all new ASICs go to large bitcoin mining companies whose supply orders can be up to 100,000 pieces or more.

It can also be noted that in the current realities, even the 2015 Antminer S7 model can generate profits. Although all these models of ASIC miners have long been thrown into the dustbin of history.

It is rather difficult to predict how long the story with super-profits in the mining of Bitcoin and other cryptocurrencies will last, therefore, it is worthwhile to approach the decision to buy ASIC miners at current inflated prices in 2021, especially with regard to old models released before 2019.
