SHA-256 Miners
The SHA 256 mining algorithm, which allows the extraction of cryptocurrencies based on first-generation blockchains, is extremely popular with manufacturers of mining equipment. But, having decided to use SHA256 asic, forget about asics with low capacities and video cards, their use will be impossible.
Below we will look at what a SHA256 miner needs to offer and review the best models. And to assess the payback of one or another miner, we recommend that you familiarize yourself with the data provided by Ultramining.

Conclusion
At the end of this review, we would like to further emphasize that it is technically still possible to mine bitcoins without special mining equipment.
However, you will earn less than one cent a month on this. Mining bitcoins on your computer will bring more problems than profits.
