Estimated guess, based on experience, USD 15-20 million.
The daily cost of running it, no idea... to many factors.
Are you saying that making the PCBs is more expensive than the mask/ASIC?
Things doesn't round up, do they?
Posted from Bitcointa.lk - #ZXH5jBVSgNxW0N6PTo open a new production line you need not only the cheap PCB´s and a large stock of chips but also machines, space, staff, raw material, clearance, storage, extra cofferooms (

) etc
Have in mind, the email says "open a parallel production line", they´re not just renting the machines next to Hashlast. The email also says production line is suppose to exist in the future, it´s not just a temporary solution.
