$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.
Look at what people pay for miners on eBay, even at this crazy price they will probably sell, so why sell them cheaper?
