S9s will be mining at a loss around June. Roi is approaching never very quickly at current btc prices.
BUT people are still buying each batch S9 released by bitmain with almost double price..CRAZY
Electricity in my country is less than 0.005$ kw/h. Some ppl will always profit...
At 0.005, there should be a limit to the amount of electricity u can use. Otherwise, your government is basically subsidizing u heavily. That means your profit is their loss.
