$4000 for a 11TH asic miner lmfao. Smoking crack I see. So... more money.. for a product that generates LESS money than the competitors... a year ago. Yea, sure. I'd rather buy up a bunch of 741's than pay $4000 for a miner that is essentially mildly better than the 741.
The mining game has mostly been for the ones that can write off a business expense or worse, launder funds into buying miners. That is why you get those crazy 'never ROI' prices.
They aren't paying straight out of their hard earned pocket money like most people hoping to do here.
