sorry Bitmain, not buying, too expensive, and there is no way I can ROI even in cheap place like Canada where it's cold and electricity is cheap. Thanks but no thanks.

even if electricty is free, with the last 10 difficulty level, that s4 will never ROI, i think you know that too , dont you ?

Nothing will. It's impossible to manufacture Mining equipment with current BTC level and costs of produce them. Market has hit turning point. too much hardware is manufactures to push the difficulty level. Manufacturer must pay the bills and get the return for the hardware produced. The risk of mining is at miners end.

10x +15% difficulty hops and game will change.
