In their calculations, Shin Yu took into account the electricity tariff of 0.45 yuan per kWh ($0,06). It turned out that the popular device Antminer from Bitmain S9 break-even point is around $4424. Thus, if the rate drops below this level, mining for S9 will cause damage.
Also, according to Xing Yu, are the most profitable to mine bitcoin using a device Terminator 2 (T2) from the Chinese holding company Innosilicon. For this equipment, the profitability threshold is around $3896.
The older and much less efficient model Antminer S7 at the current difficulty level “goes to zero” at a price around $11 594. As of 7 September, the exchange rate of bitcoin fluctuates at a mark of $6400, this means that mining on the S7 brings losses to their owners.
In addition, when mining altcoins with their current course Dash ($177), Siacoin ($0,005) and Bytom ($0,17) financial losses for the owners of devices A3 Antminer, Antminer Antminer B3 and D3, respectively.
