My guess is 1.9 to 2.4 for s4
That is good price, I would buy. But seeing BTC drop to $400 level I dont think that would be the case..
LOL so whats your goal? to make some money? Ok i get that. But why mining? oh because its like printing money.... ok i got that too.... But why BTC price drop means you wont make money? .... oh.... i get this, because you never believe in bitcoin and the technology.
If you're speculating on the price, may as well do it right, speculative trading.
