Bitmain has painted themselves into a corner. Not that it matters. They've flooded the market in a price downturn and now they can't achieve enough efficiency enhancement to up price the new tech coming. Even if they could hold watts the same and triple hashing power, they can't realistically justify a $1,500.00 S9. Things are extremely grim. I take solace in knowing that a bunch of greedy corporate maggots that went "all in" on mining are about to get their throats ripped out. No matter what their KWH rate is. I will piss on their graves.
